The producers of the SNOW 2.1 CD -added the words "Includes $5 donation to the FSF" to the front of their CD. -Walnut Creek CDROM and Info Magic, two more free software redistributors, are -also giving us a percentage of their selling price. CQ Publishing made a -large donation from the sales of their book about GAWK in Japanese. - -In the long run, the success of free software depends on how much new free -software people develop. Free software distribution offers an opportunity to -raise funds for such development in an ethical way. These redistributors -have made use of the opportunity. Many others let it go to waste. - -You can help promote free software development by convincing for-a-fee -redistributors to contribute--either by doing development themselves, or by -donating to development organizations (the FSF and others). - -The way to convince distributors to contribute is to demand and expect this -of them. This means choosing among distributors partly by how much they give -to free software development. Then you can show distributors they must -compete to be the one who gives the most. - -To make this work, you must insist on numbers that you can compare, such as, -"We will give ten dollars to the Foobar project for each disk sold." A vague -commitment, such as "A portion of the profits is donated," doesn't give you a -basis for comparison. Even a precise fraction "of the profits from this -disk" is not very meaningful, since creative accounting and unrelated -business decisions can greatly alter what fraction of the sales price counts -as profit. - -Also, press developers for firm information about what kind of development -they do or support. Some kinds make much more long-term difference than -others. For example, maintaining a separate version of a GNU program -contributes very little; maintaining a program on behalf of the GNU Project -contributes much. Easy new ports contribute little, since someone else would -surely do them; difficult ports such as adding a new CPU to the GNU compiler -contribute more; major new features and programs contribute the most. - -By establishing the idea that supporting further development is "the proper -thing to do" when distributing free software for a fee, we can assure a -steady flow of resources for making more free software. - - - -Help from Free Software Companies -********************************* - -When choosing a free software business, ask those you are considering how -much they do to assist free software development, e.g., by contributing money -to free software development or by writing free software improvements -themselves for general use. By basing your decision partially on this -factor, you can help encourage those who profit from free software to -contribute to its growth. - -These free software support companies regularly donate a part of their income -to the Free Software Foundation to support the development of new GNU -programs. Listing them here is our way of thanking them. Wingnut has made a -pledge to donate 10% of their income to the FSF, and has also purchased -several Deluxe Distribution packages in Japan. (Wingnut is SRA's special GNU -support group).

GNU manuals are intended to explain underlying concepts, -describe how to use all the features of each program, and give examples of -command use. GNU manuals are distributed as Texinfo source files, which -yield both typeset hardcopy via the TeX document formatting system, and online -hypertext display via the menu-driven Info system. Source for these manuals -comes with our software; here we list the manuals that we publish as printed -books as well; see the *note Free Software Foundation Order Form::.. - -Most GNU manuals are bound as soft cover books with "lay-flat" bindings. -This allows you to open them so they lie flat on a table without creasing the -binding. These books have an inner cloth spine and an outer cardboard cover -that will not break or crease as an ordinary paperback will. Currently, the -`GDB', `Emacs', `Emacs Lisp Reference', `GAWK', `Make', `Bison', and `Texinfo' -manuals have this binding. The other GNU manuals also lie flat when opened, -using a GBC or Wire-O binding. All of our manuals are 7in by 9.25in except -the 8.5in by 11in `Calc' manual. - -The edition number of the manual and version number of the program listed -after each manual's name were current at the time this Bulletin was published. - -`Debugging with GDB' (Edition 4.12 for Version 4.14) tells how to use the GNU -Debugger, run your program under debugger control, examine and alter data, -modify a program's flow of control, and use GDB through GNU Emacs. - -The `Emacs Manual' (11th Edition for Version 19.29) describes editing with -GNU Emacs. It explains advanced features, including outline mode and regular -expression search; how to use special modes for programming in languages like -C++ and TeX; how to use the `tags' utility; how to compile and correct code; -how to make your own keybindings; and other elementary customizations. - -`Programming in Emacs Lisp, An Introduction' (Edition 1.03 for Version 19.29) -is an elementary introduction to programming in Emacs Lisp. It is written -for people who are not necessarily interested in programming, but who do want -to customize or extend their computing environment. It tells how to write -programs that find files; switchbuffers; use searches, conditionals, loops, -and recursion; how to write Emacs initialization files; and how to run the -Emacs Lisp debuggers. If you read the text in GNU Emacs under Info mode, you -can run the sample programs directly. - -The `GNU Emacs Lisp Reference Manual' (Edition 2.4 for Version 19.29) covers -this programming language in depth, including data types, control structures, -functions, macros, syntax tables, searching/matching, modes, windows, -keymaps, byte compilation, and the operating system interface. - -The `GAWK Manual' (Edition 0.16 for Version 2.16) tells how to use the GNU -implementation of `awk'. It is written for those who have never used `awk' -and describes the features of this powerful string and record manipulation -language. - -The `Make Manual' (Edition 0.46 for Version 3.72) describes GNU `make', a -program used to rebuild parts of other programs. The manual tells how to -write "makefiles", which specify how a program is to be compiled and how its -files depend on each other. Included are an introductory chapter for novice -users and a section about automatically generated dependencies. - -The `Flex Manual' (Edition 1.03 for Version 2.3.7) teaches you to write a -lexical scanner definition for the `flex' program to create a C++ or C-coded -scanner that recognizes the patterns defined. You need no prior knowledge of -scanners. - -The `Bison Manual' (December 1993 Edition for Version 1.23) teaches you how -to write context-free grammars for the Bison program that convert into -C-coded parsers. You need no prior knowledge of parser generators. - -`Using and Porting GNU CC' (September 1994 Edition for Version 2.6) tells how -to run, install, and port the GNU C Compiler to new systems. It lists new -features and incompatibilities of GCC, but people not familiar with C will -still need a good reference on the C programming language. It also covers -G++. - -The `Texinfo Manual' (Edition 2.20 for Version 3) explains the markup -language used to generate both the online Info documentation and typeset -hardcopies. It tells you how to make tables, lists, chapters, nodes, -indexes, cross references, how to use Texinfo mode in GNU Emacs, and how to -catch mistakes. This second edition describes over 50 new commands. - -The `Termcap Manual' (2nd Edition for Version 1.2), often described as "twice -as much as you ever wanted to know about termcap," details the format of the -termcap database, the definitions of terminal capabilities, and the process -of interrogating a terminal description. This manual is primarily for -programmers. - -The `C Library Reference Manual' (Edition 0.06 for Version 1.09) describes -most of the facilities of the GNU C library, including both what Unix calls -"library functions" and "system calls." We are doing limited copier runs of -this manual until it becomes more stable. Please send corrections and -improvements to `bug-glibc-manual@prep.ai.mit.edu'. - -The `Emacs Calc Manual' (Edition 2.02 for Version 2.02) is both a tutorial -and a reference manual. It tells how to do ordinary arithmetic, how to use -Calc for algebra, calculus, and other forms of mathematics, and how to extend -Calc. - - - -GNU Software - (NOT COMPLETELY UP TO DATE) -************ - -All our software is available via FTP; see *Note How to Get GNU Software::. -In addition, we offer software on various media and printed documentation: - - * *Note CD-ROMs::. - - * *Note Tapes::. - - * *Note MS-DOS Diskettes::. - - * *Note Documentation::, which includes manuals and reference cards. - -We welcome all bug reports sent to the appropriate electronic mailing list -(*note Free Software Support::.). - -In the articles describing the contents of each medium, the version number -listed after each program name was current when we published this Bulletin. -When you order a distribution tape, diskette or newer CD-ROM, some of the -programs may be newer, and therefore the version number higher. - -Key to cross reference: - - - BinCD - Binaries CD-ROM - - DjgppD - Djgpp Diskettes - - DosCD - MS-DOS CD-ROM - - EmcsD - Emacs Diskettes - - LspEmcT - Lisps/Emacs Tape - - LangT - Languages Tape - - LiteT - 4.4BSD-Lite Tape - - SchmT - Scheme Tape - - SrcCD - Source CD-ROM - - UtilD - Selected Utilities Diskettes - - UtilT - Utilities Tape - - VMSCompT - VMS Compiler Tape - - VMSEmcsT - VMS Emacs Tape - - WdwsD - Windows Diskette - - X11OptT - X11 Optional Tape - - X11ReqT - X11 Required Tape - - - -Configuring GNU Software: - -We are using a uniform scheme for configuring GNU software packages in order -to compile them. It uses the `Autoconf' program (see item below). The goal -is to have all GNU software support the same alternatives for naming machine -and system types. When the GNU system is complete it will be possible to -configure and build the entire system at once, eliminating the need to -separately configure each individual package. The configuration scheme lets -you specify both the host and target system to build cross-compilation tools. - - - -GNU software currently available: - -(For new features and coming programs, see *Note Forthcoming GNUs::.) - - * `acm' (SrcCD, UtilT) - - `acm' is a LAN-oriented, multiplayer aerial combat simulation that runs - under the X Window System. Players engage in air to air combat against - one another using heat seeking missiles and cannons. We are working on - more accurate simulation of real airplane flight characteristics. - - * Autoconf (SrcCD, UtilT) - - Autoconf produces shell scripts which automatically configure source code - packages. These scripts adapt the packages to many kinds of Unix-like - systems without manual user intervention. Autoconf creates a script for - a package from a template file which lists the operating system features - which the package can use, in the form of `m4' macro calls. Autoconf - requires GNU `m4' to operate, but the resulting configure scripts it - generates do not. - - Most GNU programs now use Autoconf-generated configure scripts. - - * BASH (SrcCD, UtilT) - - The GNU shell, BASH (Bourne Again SHell), is compatible with the Unix - `sh' and offers many extensions found in `csh' and `ksh'. BASH has job - control, `csh'-style command history, and command-line editing (with - Emacs and `vi' modes built-in, and the ability to rebind keys) via the - readline library. BASH conforms to the POSIX 1003.2 shell specification. - - * `bc' (DjgppD, DosCD, SrcCD, UtilT) - - `bc' is an interactive algebraic language with arbitrary precision - numbers. GNU `bc' follows the POSIX.2-1992 standard, with several - extensions including multi-character variable names, an `else' - statement, and full Boolean expressions. The RPN calculator `dc' is now - distributed as part of the same package, but GNU `bc' is not implemented - as a `dc' preprocessor. - - * BFD (BinCD, DjggpD, DosCD, LangT, SrcCD) - - The Binary File Descriptor library allows a program which operates on - object files (e.g., `ld' or GDB) to support many different formats in a - clean way. BFD provides a portable interface, so that only BFD needs to - know the details of a particular format. One result is that all - programs using BFD will support formats such as a.out, COFF, and ELF. - BFD comes with source for Texinfo documentation (not yet published on - paper). Presently BFD is not distributed separately; it is included - with packages that use it. - - * Binutils (BinCD, DjgppD, DosCD, LangT, SrcCD) - - Binutils includes the programs: `ar', `c++filt', `demangle', `gas', - `gprof', `ld', `nlmconv', `nm', `objcopy', `objdump', `ranlib', `size', - `strings', and `strip'. - - Binutils Version 2 uses the BFD library. The GNU linker `ld' emits - source-line numbered error messages for multiply-defined symbols and - undefined references. It interprets a superset of the AT&T Linker - Command Language, which gives general control over where segments are - placed in memory. `nlmconv' converts object files into Novell NetWare - Loadable Modules. `objdump' can disassemble code for a29k, ALPHA, - H8/300, H8/500, HP-PA, i386, i960, m68k, m88k, MIPS, SH, SPARC, & Z8000 - processors, and can display other data (e.g., symbols & relocations) - from any file format understood by BFD. - - * Bison (BinCD, DjgppD, DosCD, LangT, SrcCD, VMSCompT) - - Bison is an upwardly compatible replacement for the parser generator - `yacc'. Texinfo source for the `Bison Manual' and reference card are - included. *Note Documentation::. - - We recently decided to change the policy for using the parsers that - Bison generates. It is now permitted to use Bison-generated parsers in - non-free programs. *Note GNUs Flashes::. - - * GNU C Library (BinCD, LangT, SrcCD) - - The GNU C library supports ANSI C-1989, POSIX 1003.1-1990 and most of the - functions in POSIX 1003.2-1992. It is upwardly compatible with 4.4BSD - and includes many System V functions, plus GNU extensions. - - The C Library will perform many functions of the Unix system calls in - the Hurd. Mike Haertel has written a fast `malloc' which wastes less - memory than the old GNU version. The GNU regular-expression functions - (`regex' and `rx') now nearly conform to the POSIX 1003.2 standard. - - GNU `stdio' lets you define new kinds of streams, just by writing a few - C functions. The `fmemopen' function uses this to open a stream on a - string, which can grow as necessary. You can define your own `printf' - formats to use a C function you have written. For example, you can - safely use format strings from user input to implement a `printf'-like - function for another programming language. Extended `getopt' functions - are already used to parse options, including long options, in many GNU - utilities. - - The C Library runs on Sun-3 (SunOS 4.1), Sun-4 (SunOS 4.1 or Solaris 2), - HP 9000/300 (4.3BSD), SONY News 800 (NewsOS 3 or 4), MIPS DECstation - (Ultrix 4), DEC Alpha (OSF/1), i386/i486 (System V, SVR4, BSD, SCO 3.2 & - SCO ODT 2.0), Sequent Symmetry i386 (Dynix 3) & SGI (Irix 4). Texinfo - source for the `GNU C Library Reference Manual' is included (*note - Documentation::.); the manual is now being updated. - - * GNU C++ Library (BinCD, DjgppD, DosCD, LangT, SrcCD) - - The GNU C++ library (libg++) contains an extensive collection of C++ - `forest' classes, an IOStream library for input/output routines, and - support tools for use with G++. Supported classes include: Obstacks, - multiple-precision Integers and Rationals, Complex numbers, arbitrary - length Strings, BitSets and BitStrings. Version 2.6.2 includes the - initial release of the libstdc++ library. This implements library - facilities defined by the forthcoming ANSI/ISO C++ standard, including - the Standard Template Library. - - * Calc (LspEmcT, SrcCD) - - Calc (written by Dave Gillespie in Emacs Lisp) is an extensible, advanced - desk calculator & mathematical tool that runs as part of GNU Emacs. You - can use Calc just as a simple four-function calculator, but it has many - more features including: choice of algebraic or RPN (stack-based) entry; - logarithmic, trigonometric & financial functions; arbitrary precision; - complex numbers; vectors; matrices; dates; times; infinities; sets; - algebraic simplification; differentiation & integration. It outputs to - `gnuplot' & comes with source for a reference card & a Manual. *Note - Documentation::. - - * GNU Chess (SrcCD, UtilT, WdwsD) - - GNU Chess lets the computer play a full game of chess with you. It runs - on most platforms & has dumb terminal, "curses" & X terminal interfaces. - The X terminal interface is based on the `xboard' program. - m{No Value For "ergegrafkludge"} GNU Chess implements many specialized - features including the null move heuristic, a hash table with aging, the - history heuristic (another form of the earlier killer heuristic), - caching of static evaluations, & a database which lets it play the first - several moves of the game quickly. Recent improvements include better - heuristics, faster evaluation, thinking on opponent's time, a perfect - King and Pawn vs King endgame routine, Swedish & German language - support, support for more book formats, a rudimentary Bobby Fischer - clock, & bug fixes. It is primarily supported by Stuart Cracraft, Chua - Kong Sian, & Tim Mann on behalf of the FSF. - - * CLISP (LspEmcT, SrcCD) - - CLISP is a Common Lisp implementation by Bruno Haible and Michael Stoll. - It mostly supports the Lisp described by `Common LISP: The Language (2nd - edition)' and the ANSI Common Lisp standard. CLISP includes an - interpreter, a byte-compiler, a large subset of CLOS, a foreign language - interface and, for some machines, a screen editor. The user interface - language (English, German, French) is chooseable at run time. Major - packages that run in CLISP include CLX & Garnet. CLISP needs only 2 MB - of memory & runs on many microcomputers (including MS-DOS systems, OS/2, - the Atari ST, Amiga 500-4000, Acorn RISC PC) & Unix-like systems - (GNU/Linux, Sun4, SVR4, SGI, HP-UX, DEC Alpha, NeXTstep & others). - - * GNU Common Lisp (LspEmcT, SrcCD) - - GNU Common Lisp (GCL) has a compiler and interpreter for Common Lisp. It - used to be known as Kyoto Common Lisp. It is very portable and extremely - efficient on a wide class of applications. It compares favorably in - performance with commercial Lisps on several large theorem-prover and - symbolic algebra systems. It supports the CLtL1 specification but is - moving towards the proposed ANSI definition. GCL compiles to C and - then uses the native optimizing C compilers (e.g., GCC). A function - with a fixed number of args and one value turns into a C function of the - same number of args, returning one value, so GCL is maximally efficient - on such calls. It has a conservative garbage collector which allows - great freedom for the C compiler to put Lisp values in arbitrary - registers. It has a source level Lisp debugger for interpreted code, - with display of source code in an Emacs window. Ita profiling tools - (based on the C profiling tools) count function calls and the time spent - in each function. CLX works with GCL. - - There is now a builtin interface with the TK widget system. It runs in - a separate process so that users may monitor progress on lisp - computations, or interact with running computations via a windowing - interface. - - There is also an Xlib interface via C (xgcl-2). PCL runs with GCL (see - PCL item later in this article). *Note Forthcoming GNUs::, for plans for - about GCL, or for recent developments. GCL version 2.0 is released - under the GNU Library General Public License. - - * `cpio' (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - `cpio' is an alternative archive program with all the features of SVR4 - `cpio', including support for the final POSIX 1003.1 `ustar' standard. - `mt', a program to position magnetic tapes, is included with `cpio'. - - * CVS (SrcCD, UtilT) - - CVS, the Concurrent Version System, manages software revision and release - control in a multi-developer, multi-directory, multi-group environment. - It works best in conjunction with RCS versions 4 and above, but will - parse older RCS formats with the loss of CVS's fancier features. See - Berliner, Brian, "CVS-II: Parallelizing Software Development," - `Proceedings of the Winter 1990 USENIX Association Conference'. To find - out how to get a copy of this report, contact `office@usenix.org'. - - * DejaGnu (LangT, SrcCD) - - DejaGnu is a framework for testing other programs that provides a single - front end for all tests. The framework's flexibility and consistency - makes it easy to write tests for any program. DejaGnu comes with - `expect', which runs scripts to conduct dialogs with programs. - - * Diffutils (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - GNU `diff' compares files showing line-by-line changes in several - flexible formats. It is much faster than traditional Unix versions. The - Diffutils package contains `diff', `diff3', `sdiff', and `cmp'. - - Recent Diffutils improvements include more consistent handling of - character sets, and a new `diff' option to do all input/output in - binary; this is useful on some non-Posix hosts. - - Plans for the Diffutils package include support for internationalization - (e.g., error messages in Chinese), and for some non-Unix PC environments. - - * DJGPP (BinCD, DjgppD, DosCD) - - DJ Delorie has ported GCC/G++ 2.6.0 (see the GCC item in this section) - to the i386 MS-DOS platform. The DJGPP package also contains a 32-bit - 80386 DOS extender with symbolic debugger; development libraries; and - ports of Bison, `flex', GAS, and the GNU Binutils. Full source code is - provided. It requires at least 5MB of hard disk space to install and - 512K of RAM to use. It supports SVGA (up to 1024x768), XMS & VDISK - memory allocation, `himem.sys', VCPI (e.g., QEMM, DESQview, & 386MAX), - and DPMI (e.g., Windows 3.x, OS/2, QEMM, & QDPMI). Ask - `djgpp-request@sun.soe.clarkson.edu' to join a DJGPP users mailing list. - - * `dld' (LangT, SrcCD) - - `dld' is a dynamic linker written by W. Wilson Ho. Linking your program - with the `dld' library allows you to dynamically load object files into - the running binary. Currently supported are VAX (Ultrix), Sun 3 (SunOS - 3.4 & 4.0), SPARC (SunOS 4.0), Sequent Symmetry (Dynix), & Atari ST. - - * `doschk' (DjgppD, DosCD, SrcCD, UtilT) - - This program is intended as a utility to help software developers ensure - that their source file names are distinguishable on System V platforms - with 14-character filenames and on MS-DOS with 8+3 character filenames. - - * `ecc' (SrcCD, UtilT) - - `ecc' is a Reed-Solomon error correction checking program, which can - correct three byte errors in a block of 255 bytes and detect more severe - errors.

GNU - Emacs is his second implementation. It offers true Lisp--smoothly - integrated into the editor--for writing extensions, and provides an - interface to the X Window System. It also runs on MS-DOS and Windows - NT. In addition to its powerful native command set, Emacs has - extensions which emulate the editors vi and EDT (DEC's VMS editor). - Emacs has many other features which make it a full computing support - environment. Our long term plan is now to move it in the direction of a - WYSIWYG word processor and make it easy for beginners to use. Source - for the `GNU Emacs Manual', `Programming in Emacs Lisp, An - Introduction', the `GNU Emacs Lisp Reference Manual', and a reference - card come with the software. *Note Documentation::. - - * GNU Emacs 18 (EmcsD, LspEmcT, SrcCD, VMSEmcsT) - - GNU Emacs 18.59 is the last release of version 18 from the FSF.

Also see *Note Forthcoming GNUs::. - - * `es' (SrcCD, UtilT) - - `es' is an extensible shell based on `rc' with first class functions, - lexical scope, exceptions, and rich return values (i.e., functions can - return values other than just numbers). `es''s extensibility comes from - the ability to modify and extend the shell's builtin services, such as - path searching and redirection. Like `rc', it is great for both - interactive use and for scripting, particularly since its quoting rules - are much less baroque than the C or Bourne shells. - - * `f2c' (LangT, SrcCD) - - `f2c' converts Fortran-77 source files into C or C++, which can be - compiled with GCC. You can get bug fixes by FTP from site - `netlib.att.com' or by email from `netlib@research.att.com'. The fixes - are summarized in the file `/netlib/f2c/changes.Z'. *Note Forthcoming - GNUs::, for information about GNU Fortran. - - * Fileutils (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - The fileutils work on files: `chgrp', `chmod', `chown', `cp', `dd', `df', - `dir', `du', `install', `ln', `ls', `mkdir', `mkfifo', `mknod', `mv', - `mvdir', `rm', `rmdir', `sync', `touch', & `vdir'. Only some of these - are on the *Note Selected Utilities Diskettes::. - - * Findutils (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - `find' is frequently used both interactively and in shell scripts to - find files which match certain criteria and perform arbitrary operations - on them. Also included are `xargs', which applies a command to a list - of files, and `locate', which scans a database for file names that match - a pattern. - - * Finger (SrcCD, UtilT) - - GNU Finger has more features than other finger programs. For sites with - many hosts, a single host may be designated as the finger "server" host, - and other hosts at that site configured as finger "clients". The server - host collects information about who is logged in to the clients. To - finger a user at a GNU Finger site, a query to any its client hosts gets - useful information. GNU Finger supports many customization features, - including user output filters, and site programmable output for special - target names. - - * `flex' (DjgppD, DosCD, LangT, SrcCD, UtilD) - - `flex' is a replacement for the `lex' scanner generator. `flex' was - written by Vern Paxson of the Lawrence Berkeley Laboratory and generates - far more efficient scanners than `lex' does. Source for the `Flex - Manual' and reference card are included. *Note Documentation::. - - * FlexFAX (UtilT) - - FlexFAX is now called HylaFAX. For more information, *Note GNU - Software::. - - * Fontutils (SrcCD, UtilT) - - The fontutils create fonts for use with Ghostscript or TeX, starting - with a scanned type image and converting the bitmaps to outlines. They - also contain general conversion programs and other utilities. - - Fontutils programs include: `bpltobzr', `bzrto', `charspace', - `fontconvert', `gsrenderfont', `imageto', `imgrotate', `limn', and - `xbfe'. - - * GAWK (DjgppD, DosCD, LangT, SrcCD) - - GAWK is upwardly compatible with the latest POSIX specification of - `awk'. It also provides several useful extensions not found in other - `awk' implementations. Texinfo source for the `GAWK Manual' comes with - the software. *Note Documentation::. - - * GCC (BinCD, DjgppD, DosCD, LangT, SrcCD, VMSCompT) - - Version 2 of the GNU C Compiler supports multiple languages; the source - file name suffix or a compiler option selects the language. The GNU C - Compiler distribution includes support for C, C++ and Objective-C. - Support for Objective-C was donated by NeXT. The runtime support needed - to run Objective-C programs is now distributed with GCC (this does not - include any Objective-C classes aside from `object'). As much as - possible, G++ is kept compatible with the evolving draft ANSI standard, - but not with `cfront' (AT&T's compiler), which has been diverging from - ANSI. - - The GNU C Compiler is a fairly portable optimizing compiler which - performs automatic register allocation, common sub-expression - elimination, invariant code motion from loops, induction variable - optimizations, constant propagation and copy propagation, delayed - popping of function call arguments, tail recursion elimination, - integration of inline functions and frame pointer elimination, - instruction scheduling, loop unrolling, filling of delay slots, leaf - function optimization, optimized multiplication by constants, a certain - amount of common subexpression elimination (CSE) between basic blocks - (though not all of the supported machine descriptions provide for - scheduling or delay slots), a feature for assigning attributes to - instructions, and many local optimizations that are automatically - deduced from the machine description. Position-independent code is - supported on the 68k, i386, i486, Pentium, Hitachi Slt, Hitachi H8/300, - Clipper, 88k, SPARC & SPARClite. - - GCC can open-code most arithmetic on 64-bit values (type `long long - int'). It supports extended floating point (type `long double') on the - 68k; other machines will follow. - - GCC supports full ANSI C, traditional C & GNU C extensions (including: - nested functions support, nonlocal gotos & taking the address of a - label). - - GCC can generate a.out, COFF, ELF & OSF-Rose files when used with a - suitable assembler. It can produce debugging information in these - formats: BSD stabs, COFF, ECOFF, ECOFF with stabs & DWARF. - - GCC generates code for many CPUs, including: a29k, Alpha, ARM, AT&T - DSP1610, Convex cN, Clipper, Elxsi, Fujitsu Gmicro, H8/300, HP-PA (1.0 - and 1.1) i370, i386, i486, Pentium, i860, i960, m68k, m68020, m68030, - m68040, m88k, MIL-STD-1750a, MIPS, ns32k, PDP-11, Pyramid, ROMP, RS6000, - SH, SPARC, SPARClite, VAX, & we32k. - - Operating systems supported include: AIX, ACIS, AOS, BSD, Clix, Ctix, - DG/UX, Dynix, Genix, GNU, HP-UX, ISC, Irix, GNU/Linux, Luna, LynxOS, - Mach, Minix, NetBSD, NewsOS, OSF, OSF-Rose, RISCOS, SCO, Solaris 2, - SunOS 4, SysV, Ultrix, Unos, VMS & Windows/NT. - - Using the configuration scheme for GCC, building a cross-compiler is as - easy as building a native compiler. - - We no longer maintain version 1 of GCC, G++, or libg++. - - Texinfo source for the `Using and Porting GNU CC' manual, is included - with GCC. *Note Forthcoming GNUs::, for plans for later releases of - GCC. - - * GDB (BinCD, DjgppD, DosCD, LangT, SrcCD) - - GDB, the GNU DeBugger, is a source-level debugger which supports C, C++, - and Fortran. - - GDB can debug both C and C++ programs, and will work with executables - produced by many different compilers; however, C++ debugging will have - some limitations if you do not use GCC. - - GDB has a command line user interface; GNU Emacs comes with a GDB mode, - and `xxgdb' provides an X interface (but it is not distributed or - maintained by the FSF; FTP it from `ftp.x.org' in the - `/contrib/utilities' directory). - - Executable files and symbol tables are read via the BFD library, which - allows a single copy of GDB to debug programs with multiple object file - formats (e.g., a.out, COFF, ELF). Other features include a rich command - language, remote debugging over serial lines or TCP/IP, and watchpoints - (breakpoints triggered when the value of an expression changes). - - GDB defines a standard interface for simulators, and the included - simulator library includes simulators for the Zilog Z8001/2, Hitachi - H8/300, H8/500 & Super-H. - - GDB can perform cross-debugging. To say that GDB "targets" a platform - means that it can perform native or cross-debugging for it. To say that - GDB can "host" a given platform means that it can be built on it, but - cannot necessarily debug native programs. GDB can: - - * "target" & "host": Amiga 3000 (Amix), DEC Alpha (OSF/1), DECstation - 3100 & 5000 (Ultrix), HP 9000/300 (BSD, HP-UX), HP 9000/700 (HP-UX), - i386 (BSD, FreeBSD, GNU/Linux, LynxOS, NetBSD, SCO), IBM RS/6000 - (AIX, LynxOS), Motorola Delta m88k (System V, CX/UX), PC532 - (NetBSD), Motorola m68k MVME-167 (LynxOS), NCR 3000 (SVR4), SGI - (Irix V3, V4, V5), SONY News (NewsOS 3.x), SPARC (SunOS 4.1, - Solaris, NetBSD, LynxOS) Sun-3 (SunOS 4.1), & Ultracomputer (a29k - running Sym1). - - * "target", but not "host": AMD 29000 (COFF & a.out), Hitachi H8/300, - Hitachi SH, i386 (a.out, COFF, OS/9000) i960 (Nindy, VxWorks), - m68k/m68332 (a.out, COFF, VxWorks), MIPS (IDT ecoff, ELF), Fujitsu - SPARClite (a.out, COFF), & Z8000. - - * "host", but not "target": IBM RT/PC (AIX), and HP/Apollo 68k (BSD). - - GDB can use the symbol tables emitted by the vendor-supplied compilers of - most MIPS-based machines, including DEC. (These tables are in a format - which almost nobody else uses.) Source for the manual - `Debugging with GDB' and a reference card are included. *Note - Documentation::. - - * `gdbm' (LangT, SrcCD, UtilD) - - `gdbm' is the GNU replacement for the traditional `dbm' and `ndbm' - libraries. It implements a database using quick lookup by hashing. - `gdbm' does not ordinarily make sparse files (unlike its Unix and BSD - counterparts). - - * Ghostscript (DjgppD, DosCD, SrcCD, UtilT) - - GNU Ghostscript is the GNU release of Ghostscript, which is an - interpreter for the Postscript graphics language (*note Forthcoming - GNUs::., for news on future plans). - - The current version of GNU Ghostscript is 2.6.2. Features include the - ability to use the fonts provided by the platform on which Ghostscript - runs (X Window System and Microsoft Windows), resulting in much - better-looking screen displays; improved text file printing (like - `enscript'); a utility to extract the text from a Postscript language - document; a much more reliable (and faster) Microsoft Windows - implementation; support for Microsoft C/C++ 7.0; drivers for many new - printers, including the SPARCprinter, and for TIFF/F (fax) file format; - many more Postscript Level 2 facilities, including most of the color - space facilities (but not patterns), and the ability to switch between - Level 1 and Level 2 dynamically. Version 2.6.2 adds a LaserJet 4 driver - and several important bug fixes to version 2.6.1. - - Ghostscript executes commands in the Postscript language by writing - directly to a printer, drawing on an X window, or writing to a file for - later printing (or to a bitmap file that you can manipulate with other - graphics programs). - - Ghostscript includes a C-callable graphics library (for client programs - that do not want to deal with the Postscript language). It also supports - IBM PCs and compatibles with EGA, VGA, or SuperVGA graphics (but please - do *not* ask the FSF staff any questions about this; we do not use PCs). - - * Ghostview (SrcCD, UtilT) - - Tim Theisen, `ghostview@cs.wisc.edu', has created Ghostview, a previewer - for multi-page files with an X11 user interface. Ghostview and - Ghostscript function as two cooperating programs; Ghostview creates a - viewing window and Ghostscript draws in it. - - * `gmp' (LangT, SrcCD) - - GNU mp is a library for arbitrary precision arithmetic on signed integers - and rational numbers. It has a rich set of functions with a regular - interface. - - * GNATS (SrcCD, UtilT) - - GNATS (GNats: A Tracking System, not to be confused with GNAT, The GNU - Ada Translator) is a bug-tracking system. It is based upon the paradigm - of a central site or organization which receives problem reports and - negotiates their resolution by electronic mail. Although it has been - used primarily as a software bug-tracking system so far, it is - sufficiently generalized so that it could be used for handling system - administration issues, project management or any number of other - applications. - - * `gnuplot' (SrcCD, UtilT, WdwsD) - - `gnuplot' is an interactive program for plotting mathematical - expressions and data. It handles both curves (2 dimensions) and surfaces - (3 dimensions). Curiously, the program was neither written nor named for - the GNU Project; the name is a coincidence. Various GNU programs use - `gnuplot' to produce graphical output. - - * GnuGo (SrcCD, UtilT) - - GnuGo plays the game of Go (Wei-Chi); it is not yet very sophisticated. - - * `gperf' (LangT, SrcCD) - - `gperf' generates perfect hash tables. There are two implementations of - `gperf', written in C and C++. Both produce hash functions in either C - or C++. - - * GNU Graphics (SrcCD, UtilT) - - GNU Graphics is a system which produces x-y plots from ASCII or binary - data. It supports output in Postscript, Tektronix 4010 compatible and - Unix device-independent "plot" formats as well as a previewer for the X - Window System. Features include a `spline' interpolation program; - examples of shell scripts using `graph' and `plot'; and a statistics - toolkit; and output in TekniCAD TDA and ln03 file formats. Email bugs or - questions to Rich Murphey, `Rich@lamprey.utmb.edu'. - - * grep (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - This package has GNU `grep', `egrep', and `fgrep' which find lines that - match inputed patterns. They are much faster than the traditional Unix - versions. - - * Groff (DjgppD, DosCD, SrcCD, UtilT) - - Groff is a document formatting system based on an implementation of - device-independent troff, which also includes implementations of `eqn', - `nroff', `pic', `refer', `tbl', `troff', and the `man', `ms', and `mm' - macros, as well as drivers for Postscript, TeX `dvi' format, and - typewriter-like devices. - - Groff's `mm' macro package is almost compatible with the DWB `mm' macros - and has several extensions. Also included is a modified version of the - Berkeley `me' macros and an enhanced version of the X11 `xditview' - previewer. Written in C++, these programs can be compiled with GNU C++ - Version 2.5 or later. A driver for the LaserJet 4 series of printers is - currently in test. - - Groff users are encouraged to contribute enhancements. Most needed are - complete Texinfo documentation, a `grap' emulation (a `pic' preprocessor - for typesetting graphs), a page-makeup postprocessor similar to `pm' - (see `Computing Systems', Vol. 2, No. 2; ask `office@usenix.org' how to - get a copy) and an ASCII output class for `pic' so that `pic' can be - integrated with Texinfo. Questions and bug reports from users who have - read the documentation provided with groff can be sent to - `bug-groff@prep.ai.mit.edu'. - - * `gzip' (DjgppD, DosCD, LangT, LspEmcT, SrcCD, UtilT) - - Some of the contents of our tape and FTP distributions are compressed. - We have software on our tapes and FTP sites to uncompress these files. - Due to patent troubles with `compress', we use another compression - program, `gzip'. (Such prohibitions on software development are fought - by the League for Programming Freedom, *note What Is the LPF::., for - details.) `gzip' can expand LZW-compressed files but uses another, - unpatented algorithm for compression which generally produces better - results. It also expands files compressed with System V's `pack' - program. - - * `hello' (DjgppD, DosCD, SrcCD, UtilT) - - The GNU `hello' program produces a familiar, friendly greeting. It - allows non-programmers to use a classic computer science tool which would - otherwise be unavailable to them. Because it is protected by the GNU - General Public License, users are free to share and change it. - - Like any truly useful program, `hello' contains a built-in mail reader. - - * `hp2xx' (SrcCD, UtilT) - - GNU `hp2xx' reads HP-GL files, decomposes all drawing commands into - elementary vectors, and converts them into a variety of vector and raster - output formats. It is also an HP-GL previewer. Currently supported - vector formats include encapsulated Postscript, Uniplex RGIP, Metafont - and various special TeX-related formats, and simplified HP-GL (line - drawing only) for imports. Raster formats supported include IMG, PBM, - PCX, & HP-PCL (including Deskjet & DJ5xxC support). Previewers work - under X11 (Unix), OS/2 (PM & full screen), MS-DOS (SVGA, VGA, & HGC). - - * HylaFAX (UtilT) - - HylaFAX is a facsimile system for Unix systems. It supports sending, - receiving, and polled retrieval of facsimile, as well as transparent - shared data use of the modem. Information is also available on the - World Wide Web at URL: `http://www.vix.com/hylafax/'. - - * `indent' (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - GNU `indent' is a revision of the BSD version. By default, it formats C - source according to the GNU coding standards. The BSD default, K&R and - other formats are available as options. It is also possible to define - your own format. GNU `indent' is more robust and provides more - functionality than other versions, e.g., it handles C++ comments. - - * Ispell (DjgppD, DosCD, SrcCD, UtilT) - - Ispell is an interactive spell checker that suggests "near misses" as - replacements for unrecognized words. System & user-maintained - dictionaries for multiple languages can be used. Standalone & GNU Emacs - interfaces are available. Previously, the GNU Project had its own - version of ispell ("Ispell 4.0"), but has dropped it for a parallel - branch that has had more development ("Ispell 3.1"). (Version 3 was an - earlier release from the original Ispell author, but others have since - made it more sophisticated.) - - * JACAL *Not available from the FSF* - - JACAL is a symbolic mathematics system for the manipulation and - simplification of equations and single and multiple-valued algebraic - expressions constructed of numbers, variables, radicals, differential - operators, and algebraic and holonomic functions. Vectors, matrices, - and tensors of these objects are also supported. - - JACAL was written in Scheme by Aubrey Jaffer. It comes with SCM, an IEEE - P1178 and R4RS compliant version of Scheme written in C. SCM runs on - Amiga, Atari-ST, MS-DOS, OS/2, NOS/VE, Unicos, VMS, Unix, and similar - systems. SLIB is a portable Scheme library used by JACAL. - m{No Value For "ergegrafkludge"} The FSF is not distributing JACAL on - any media. To receive an IBM PC floppy disk with the source and - executable files, send $99.00 to: - Aubrey Jaffer - 84 Pleasant Street - Wakefield, MA 01880-1846 - USA - - * `less' (SrcCD, UtilD, UtilT) - - `less' is a display paginator similar to `more' and `pg' but with - various features (such as the ability to scroll backwards) that most - pagers lack. - - * `m4' (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - GNU `m4' is an implementation of the traditional Unix macro processor. - It is mostly SVR4 compatible, although it has some extensions (for - example, handling more than 9 positional parameters to macros). `m4' - also has built-in functions for including files, running shell commands, - doing arithmetic, etc. - - * `make' (BinCD, DjgppD, DosCD, LangT, LspEmcT, SrcCD, UtilD, - UtilT) - - GNU `make' supports POSIX 1003.2 and has all but a few obscure features - of the BSD and System V versions of `make', as well as many of our own - extensions. GNU extensions include long options, parallel compilation, - flexible implicit pattern rules, conditional execution and powerful text - manipulation functions. Texinfo source for the `Make Manual' comes with - the program. *Note Documentation::. - - GNU `make' is on several of our tapes because some system vendors supply - no `make' utility at all, and some native `make' programs lack the - `VPATH' feature essential for using the GNU configure system to its full - extent. The GNU `make' sources have a shell script to build `make' - itself on such systems. - - MS-DOS binaries for `make' are available with the DJGPP distribution. - - * MandelSpawn (SrcCD, UtilT) - - A parallel Mandelbrot generation program for the X Window System. - - * mtools (SrcCD, UtilT) - - mtools is a set of public domain programs to allow Unix systems to read, - write and manipulate files on an MS-DOS file system (usually a diskette). - - * MULE (EmcsD, DosCD, SrcCD) - - MULE is a MULtilingual Enhancement to GNU Emacs. It can handle many - character sets at once including Japanese, Chinese, Korean, Vietnamese, - Thai, Greek, the ISO Latin-1 through Latin-8 character sets, Ukrainian, - Arabic, Hebrew, Russian, and other Cyrillic alphabets. A text buffer in - MULE can contain a mixture of characters from these languages. To input - any of these characters, you can use various input methods provided by - MULE itself. In addition, if you use MULE under some terminal emulators - (kterm, cxterm, or exterm), you can use its input methods. MULE is - being merged into GNU Emacs. *Note GNU and Other Free Software in - Japan::, for more information about MULE. - - * NetHack (SrcCD, UtilT) - - NetHack is a display-oriented adventure game similar to Rogue. Both - ASCII and X displays are supported. - - * NIH Class Library (LangT, SrcCD) - - The NIH Class Library (formerly known as "OOPS", Object-Oriented Program - Support) is a portable collection of C++ classes, similar to those in - Smalltalk-80, which has been developed by Keith Gorlen of the National - Institutes of Health (NIH), using the C++ programming language. - - * `nvi' (SrcCD, UtilT) - - `nvi' is a free implementation of the `vi'/`ex' Unix editor.

It runs under GNU/Linux, BSD, NetBSD, FreeBSD, - BSDI, AIX, HP-UX, DGUX, IRIX, PSF, PTX, Solaris, SunOS, Ultrix, Unixware - & should port easily to many other systems. - - * GNU Objective-C Library (LangT, SrcCD) - - The GNU Objective-C Class Library (`libobjects') is a library of - general-purpose, non-graphical Objective-C objects written by Andrew - McCallum and other volunteers. It includes collection classes for - maintaining groups of objects and C types, streams for I/O to various - destinations, coders for formatting objects and C types to streams, ports - for network packet transmission, distributed objects (remote object - messaging), string classes, pseudo-random number generators, and time - handling facilities. The package will also include the foundation - classes for the GNUStep project; over 50 of these classes have already - been implemented. The library is known to work on i386, i486, Pentium, - m68k, SPARC, MIPS, & RS6000. Send queries and bug reports to - `mccallum@gnu.ai.mit.edu'. - - * `OBST' (LangT, SrcCD) - - `OBST' is a persistent object management system with bindings to C++. - `OBST' supports incremental loading of methods. Its graphical tools - require the X Window System. It features a hands-on tutorial including - sample programs. It compiles with g++ and should install easily on most - Unix platforms. - - * Octave (LangT, SrcCD) - - Octave is a high-level language similar to MATLAB that is primarily - intended for numerical computations. It provides a convenient command - line interface for solving linear and nonlinear problems numerically. - m{No Value For "ergegrafkludge"} Octave does arithmetic for real and - complex scalars and matrices, solves sets of nonlinear algebraic - equations, integrates systems of ordinary differential and - differential-algebraic equations, and integrates functions over finite - and infinite intervals. Two- and three-dimensional plotting is - available using `gnuplot'. Send queries and bug reports to: - `bug-octave@che.utexas.edu'. Source is included for a 220+ page - Texinfo manual, which is not yet published by the FSF. - - * Oleo (SrcCD, UtilT) - - Oleo is a spreadsheet program (better for you than the more expensive - spreadsheets). It supports the X Window System and character-based - terminals, and can output Embedded Postscript renditions of spreadsheets. - Keybindings should be familiar to Emacs users and are configurable. - Under X and in Postscript output, Oleo supports multiple, variable width - fonts. *Note Forthcoming GNUs::, for the plans for later releases of - Oleo. - - * `p2c' (LangT, SrcCD) - - `p2c' is a Pascal-to-C translator written by Dave Gillespie.

It runs under both GCL and CLISP, mentioned above. - - * `perl' (LangT, SrcCD) - - Larry Wall's `perl' combines the features and capabilities of `sed', - `awk', `sh' and C, as well as interfaces to the Unix system calls and - many C library routines. - - * `ptx' (SrcCD, UtilD, UtilT) - - GNU `ptx' is our version of the traditional permuted index generator. - It handles multiple input files at once, produces TeX compatible output, - & outputs readable "KWIC" (KeyWords In Context) indexes. It does not - yet handle input files that do not fit in memory all at once. - - * `rc' (SrcCD, UtilT) - - `rc' is a shell that features a C-like syntax (much more so than `csh') - and far cleaner quoting rules than the C or Bourne shells. It's - intended to be used interactively, but is also great for writing - scripts. It inspired the shell `es'. - - * RCS (SrcCD, UtilD, UtilT) - - RCS, the Revision Control System, is used for version control & - management of software projects. When used with GNU `diff', RCS can - handle binary files (executables, object files, 8-bit data, etc). Also - see the item about CVS in this section. - - * `recode' (SrcCD, UtilT) - - GNU `recode' converts files between character sets and usages. When - exact transliterations are not possible, it may get rid of the offending - characters or fall back on approximations. This program recognizes or - produces nearly 150 different character sets and is able to - transliterate files between almost any pair. Most RFC 1345 character - sets are supported. - - * regex (LangT, SrcCD) - - The GNU regular expression library supports POSIX.2, except for - internationalization features. It is included in many GNU programs which - do regular expression matching and available separately. An alternative - regular expression package, `rx', comes with `sed'; it has the potential - to be faster than `regex' in most cases, but still needs work. - - * Scheme (SchmT, SrcCD) - - For information about Scheme, see *Note Scheme Tape::. - - * `screen' (SrcCD, UtilT) - - `screen' is a terminal multiplexer that runs several separate "screens" - (ttys) on a single character-based terminal. Each virtual terminal - emulates a DEC VT100 plus several ISO 6429 (ECMA 48, ANSI X3.64) and ISO - 2022 functions. Arbitrary keyboard input translation is also supported. - `screen' sessions can be detached and resumed later on a different - terminal type. Output in detached sessions is saved for later viewing. - - * `sed' (DjgppD, DosCD, SrcCD, UtilD, UtilT) - - `sed' is a stream-oriented version of `ed'. GNU `sed' comes with the - `rx' library, a faster version of `regex' (*note Forthcoming GNUs::.). - - * Sharutils (SrcCD, UtilT) - - `shar' makes so-called shell archives out of many files, preparing them - for transmission by electronic mail services, while `unshar' helps - unpack these shell archives after reception. `uuencode' prepares a file - for transmission over an electronic channel which ignores or otherwise - mangles the high order bit of bytes, while `uudecode' does the converse - transformation. - - * Shellutils (DjgppD, DosCD, SrcCD, UtilT) - - Use shellutils interactively or in shell scripts: `basename', `date', - `dirname', `echo', `env', `expr', `false', `groups', `hostname', `id', - `logname', `nice', `nohup', `pathchk', `printenv', `printf', `pwd', - `sleep', `stty', `su', `tee', `test', `true', `tty', `uname', `users', - `who', `whoami', and `yes'. - - * GNU Shogi (SrcCD, UtilT) - - Shogi is a Japanese game similar to Chess; a major difference is that - captured pieces can be returned into play. GNU Shogi is a variant of - GNU Chess; GNU Shogi implements the same features as GNU Chess and uses - similar heuristics. As a new feature, sequences of partial board - patterns can be introduced in order to help the program play toward - specific opening patterns. There are both character and X display - interfaces. GNU Shogi is primarily supported by Matthias Mutz on - behalf of the FSF. - - * Smalltalk (LangT, SrcCD) - - GNU Smalltalk is an interpreted object-oriented programming language - system written in highly portable C. It has been successfully ported to - many Unix and some other platforms, including DOS (but these non-Unix - ports are not available from the FSF). Current features include a - binary image save capability, the ability to invoke user-written C code - and pass parameters to it, a GNU Emacs editing mode, a version of the X - protocol invocable from Smalltalk, optional byte-code compilation - tracing and byte-code execution tracing, and automatically loaded - per-user initialization files. It implements all of the classes and - protocol in the Smalltalk-80 book "Smalltalk-80: The Language", except - for the graphic user interface (`GUI') related classes. - - *Note Forthcoming GNUs::, for plans for later releases of Smalltalk. - - * Superopt (LangT, SrcCD) - - Superopt is a function sequence generator that uses an exhaustive - generate-and-test approach to find the shortest instruction sequence for - a given function. You provide a function as input, a CPU to generate - code for, and how many instructions you can accept. Its application in - GCC is described in the `ACM SIGPLAN PLDI'92' proceedings. Superopt - supports: SPARC, m68k, m68020, m88k, IBM RS/6000, AMD 29000, Intel - 80x86, Pyramid, DEC Alpha, & HP-PA. - - * `tar' (SrcCD, UtilT) - - GNU `tar' includes multivolume support, the ability to archive sparse - files, automatic archive compression/decompression, remote archives and - special features that allow `tar' to be used for incremental and full - backups. Unfortunately, GNU `tar' implements an early draft of the - POSIX 1003.1 `ustar' standard which is different from the final - standard. Adding support for the new changes in a backward-compatible - fashion is not trivial. - - * Termcap Library (SrcCD, UtilT) - - The GNU Termcap library is a drop-in replacement for `libtermcap.a' on - any system. It does not place an arbitrary limit on the size of Termcap - entries, unlike most other Termcap libraries. Included is source for the - `Termcap Manual' in Texinfo format. *Note Documentation::. - - * TeX (SrcCD) - - TeX is a document formatting system that handles complicated - typesetting, including mathematics. It is GNU's standard text formatter. - - You can obtain TeX from the University of Washington, which maintains and - supports a tape distribution of TeX for Unix systems. The core material - consists of Karl Berry's `web2c' TeX package, the sources for which are - available via anonymous ftp; retrieval instructions are in - `pub/tex/unixtex.ftp' on `ftp.cs.umb.edu'. If you receive any - installation support from the University of Washington, please consider - sending them a donation. - - To order a full distribution written in `tar' on either a 1/4inch - 4-track QIC-24 cartridge or a 4mm DAT cartridge, send $210.00 to: - - Pierre A. MacKay - Department of Classics - DH-10, Denny Hall 218 - University of Washington - Seattle, WA 98195 - USA - - Electronic-Mail: `mackay@cs.washington.edu' - Telephone: +1-206-543-2268 - - Please make checks payable to the University of Washington. Do not - specify any other payee. That causes accounting difficulties. Checks - must be in U.S. dollars, drawn on a U.S. bank. Prepaid orders are the - only orders that can now be handled. Overseas sites: please add to the - base cost $20.00 for shipment via air parcel post, or $30.00 for - shipment via courier. Please check with the above for current prices - and formats. - - * Texinfo (DjgppD, DosCD, LangT, LspEmcT, SrcCD, UtilD, UtilT) - - Texinfo is a set of utilities which generate both printed manuals and - online hypertext documentation (called "Info"). There are also programs - for reading online Info documents. Version 3 has both GNU Emacs Lisp - and standalone programs written in C or shell script. Texinfo mode for - GNU Emacs enables easy editing and updating of Texinfo files. Programs - provided include `makeinfo', `info', `texi2dvi', `texindex', `tex2patch', - and `fixfonts'. Source for the `Texinfo Manual' is included. *Note - Documentation::. - - * Textutils (DjgppD, DosCD, SrcCD, UtilT) - - The Textutils programs manipulate textual data.

Many Forth libraries with - full documentation are available including ones for top-down parsing, - multi-threads, and object oriented programming. - - * `time' (SrcCD, UtilT) - - `time' is used to report statistics (usually from a shell) about the - amount of user, system and real time used by a process. On some systems - it also reports memory usage, page faults, and other statistics. - - * `tput' (SrcCD, UtilT) - - `tput' is a portable way for shell scripts to use special terminal - capabilities. Our `tput' uses the Termcap database, instead of Terminfo - as most others do. - - * UUCP (SrcCD, UtilT) - - This version of UUCP was written by Ian Lance Taylor, and is GNU's - standard UUCP system. It supports the `f', `g' and `v' (in all window - and packet sizes), `G', `t', `e', Zmodem and two new bidirectional (`i' - and `j') protocols. If you have a Berkeley sockets library, it can make - TCP connections. If you have TLI libraries, it can make TLI - connections. Source is included for a Texinfo manual, which is not yet - published by the FSF. - - * `wdiff' (DjgppD, DosCD, SrcCD, UtilT) - - `wdiff' is a front-end to GNU `diff'. It compares two files, finding - the words deleted or added to the first to make the second. It has many - output formats and works well with terminals and pagers. `wdiff' is - very useful when two texts differ only by a few words and paragraphs - have been refilled. - - * `Ygl' (SrcCD, UtilT) - - `Ygl' emulates SGI's GL (Graphics Language) library under X11. It runs - under GNU/Linux with XFree, AIX 3.2, ConvexOS, HP-UX 7.0/8.0/9.0, SunOS - and many others. - - - -Program/Package Cross Reference - (NOT COMPLETELY UP TO DATE) -******************************* - -Here is a list of what package each GNU program or library is in.

It was designed at -MIT and other universities to teach students the art of programming, and to -research new parallel programming constructs and compilation techniques. - -This tape now contains MIT Scheme 7.3, which conforms to the "Revised^4 -Report On the Algorithmic Language Scheme" (MIT AI Lab Memo 848b), for which -TeX source is included. It is written partly in C, but is presently hard to -bootstrap. Binaries that can be used to bootstrap Scheme are available for: - - * HP 9000 series 300, 400, 700 & 800 running HP-UX 7.0 or 8.0 - - * NeXT running NeXT OS 1.0 or 2.0 - - * Sun-3 or Sun-4 running SunOS 4.1 - - * DECstation 3100/5100 running Ultrix 4.0 - - * Sony NeWS-3250 running NEWS OS 5.01 - - * Vax running 4.3BSD - -If your system is not on this list and you don't enjoy the bootstrap -challenge, see the JACAL item in *Note GNU Software::. - - - -X11 Tapes ---------- - -The two X11 tapes contain Version 11, Release 6 of the X Window System. The -first tape contains all of the core software, documentation and some -contributed clients. We call this the "required" X tape since it is -necessary for running X or running GNU Emacs under X. The second, "optional" -tape contains contributed libraries and other toolkits, the Andrew User -Interface System, games, and other programs. - -The X11 Required tape also contains all fixes and patches released to date. -We update this tape as new fixes and patches are released for programs on -both tapes. *Note Tape & CD-ROM Subscription Service::. - -We will distribute X11R5 on tape until X11R6 is stable, and on the *Note -November 1993 Source Code CD-ROM::, while supplies last. - - - -Berkeley 4.4BSD-Lite Tape -------------------------- - -The "4.4BSD-Lite" release is the last from the Computer Systems Research -Group at the University of California at Berkeley. It has most of the BSD -software system, except for a few files that remain proprietary. It is much -more complete than the previous "Net2" release. - - - -VMS Emacs and VMS Compiler Tapes --------------------------------- - -We offer two VMS tapes. One has just GNU Emacs 18.59 (none of the other -software on the *Note Lisps/Emacs Tape::, is included). The other has GCC -2.3.3, Bison 1.19 (to compile GCC), GAS 1.38 (to assemble GCC's output) and -some library and include files (none of the other software on the *Note -Languages Tape::, is included). We are not aware of a GDB port for VMS. -Both VMS tapes have DEC VAX executables from which you can bootstrap, as the -DEC VMS C compiler cannot compile GCC. We do not have executables for DEC -Alpha VMS systems. Please do not ask us to devote effort to VMS support, -because it is peripheral to the GNU Project. - - - -CD-ROMs -******* - -We offer these CD-ROMs: - - * *Note MS-DOS CD-ROM::, expected in September 1995. - - * *Note Debian GNU/Linux CD-ROM::, expected in late fall 1995. - - * *Note Compiler Tools Binaries CD-ROM::. - - * *Note June 1995 Source Code CD-ROM::. - - * *Note May 1994 Source Code CD-ROM::. - - * *Note November 1993 Source Code CD-ROM::. - -Our CD-ROMs are in ISO 9660 format & can be mounted as a read-only file -system on most computers. If your driver supports it you can mount each -CD-ROM with "Rock Ridge" extensions (the MS-DOS CD-ROM is only in ISO 9660 -format) & it will look just like an ordinary Unix file system, rather than -one full of truncated & otherwise mangled names that fit vanilla ISO 9660. - -You can build most of the software without copying the sources off the CD. -You only need enough disk space for object files and intermediate build -targets. - - - -Pricing of the GNU CD-ROMs --------------------------- - -If a business or organization is ultimately paying, the June 1995 Source CD -costs $240. It costs $60 if you, an individual, are paying out of your own -pocket. The December 1994 Compiler Tools Binaries CD-ROM costs $220 for a -business or organization, and $55 for an individual. - - - -What do the individual and company prices mean? - -The software on our disk is free; anyone can copy it and anyone can run it. -What we charge for is the physical disk and the service of distribution. - -We charge two different prices depending on who is buying. When a company or -other organization buys the June 1995 Source CD-ROM, we charge $240. When an -individual buys the same disk, we charge just $60. - -This distinction is not a matter of who is allowed to use the software. In -either case, once you have a copy, you can distribute as many copies as you -wish, and there's no restriction on who can have or run them. The price -distinction is entirely a matter of what kind of entity pays for the CD. - -You, the reader, are certainly an individual, not a company. If you are -buying a disk "in person", then you are probably doing so as an individual. -But if you expect to be reimbursed by your employer, then the disk is really -for the company; so please pay the company price and get reimbursed for it. -We won't try to check up on you--we use the honor system--so please cooperate. - -Buying CDs at the company price is very helpful for GNU; just 140 Source CDs -at that price supports an FSF programmer or tech writer for a year. - - - -Why is there an individual price? - -In the past, our distribution tapes have been ordered mainly by companies. -The CD at the price of $240 provides them with all of our software for a much -lower price than they would previously have paid for six different tapes. To -lower the price more would cut into the FSF's funds very badly, and decrease -the software development we can do. - -However, for individuals, $240 is too high a price; hardly anyone could -afford that. So we decided to make CDs available to individuals at the lower -price of $60. - - - -Is there a maximum price? - -Our stated prices are minimum prices. Feel free to pay a higher price if you -wish to support GNU development more. The sky's the limit; we will accept as -high a price as you can offer. Or simply give a donation (tax-deductible in -the U.S.) to the Free Software Foundation, a tax-exempt public charity. - - - -MS-DOS CD-ROM -------------- - -We expect to release our first CD-ROM for MS-DOS in September, 1995. Contact -either address on page 1 for more information at that time. The MS-DOS CD -will be packaged inside a book describing its contents. It will have all the -sources and executables on the MS-DOS Diskettes. For details and version -numbers, *note MS-DOS Diskettes::.. - - - -Debian GNU/Linux CD-ROM ------------------------ - -The FSF expects to ship a CD-ROM with Debian GNU/Linux on it in the late fall -1995. This CD will be packaged inside a book describing its contents. -m{No Value For "ergegrafkludge"} Debian GNU/Linux is a complete operating -system for x86 machines, available in both source code and binary form. It -is a GNU/Linux system--that is to say, a variant GNU system which uses Linux -as the kernel. (All the systems now available which use the Linux kernel are -GNU/Linux systems.) - -Debian is being developed by Ian Murdock and the Debian Association in -conjunction with the Free Software Foundation. We are distributing it as an -interim measure until the GNU kernel (the Hurd) is ready for users. - -Debian GNU/Linux is available for FTP at `ftp.cps.cmich.edu' in file -`/pub/debian'. For more information about the Debian Project and how to get -involved, see `/pub/gnu/GNUinfo/DEBIAN' on a GNU FTP host (*note How to Get -GNU Software::. for a list). - - - -December 1994 Compiler Tools Binaries CD-ROM --------------------------------------------- - -We are now offering a CD-ROM that contains executables for GNU compiler tools -for some systems which lack a compiler. This enables the people who use -these systems to compile GNU and other free software without having to buy a -proprietary compiler. You can also use the GNU compilation system to compile -your own C/C++/Objective-C programs. - -We hope to have more systems on each update of this CD. If you can help -build binaries for new systems (especially those that don't come with a C -compiler), or have one to suggest, please contact us at the addresses on page -1. - -These packages: - - *DJGPP 1.12.m2 from GCC 2.6.0 - *GCC/G++/Objective-C 2.6.2 - *GNU C Library 1.09 - *GDB 4.13 - *Binutils 2.5.2 - *Bison 1.22 - *Emacs 19.26 (MS-DOS only) - *Flex 2.4.7 - *Make 3.72.1 - *libg++ 2.6.1 - -On these platforms: - - *`i386-msdos' - *`hppa1.1-hp-hpux9' - *`sparc-sun-solaris2' - *`sparc-sun-sunos4.1' - - - -Source Code CD-ROMs -------------------- - -We have several versions of our Source Code CD-ROMs available: - - * *Note June 1995 Source Code CD-ROM::. - - * *Note May 1994 Source Code CD-ROM::. - - * *Note November 1993 Source Code CD-ROM::. - -The older Source Code CDs will be available while supplies last at a reduced -price; see the *note Free Software Foundation Order Form::.. - -All of the Source Code CDs also contain Texinfo source for the GNU manuals -listed in *Note Documentation::. - -The VMS tapes' contents are *not* included. Many programs that are only on -MS-DOS diskettes and not on the tapes are also *not* included. The contents -of the MIT Scheme & X11 Optional tapes are *not* on the November 1993 & May -1994 Source CDs. *Note Tapes:: & *Note MS-DOS Diskettes::. - -There are no precompiled programs on these Source CDs.

For a one-time cost equivalent to -three tapes or CD-ROMs (plus shipping in some cases), we will ship you four -new versions of the tape of your choice or the Source Code CD-ROM. The tapes -are sent each quarter; the CD-ROMs are sent as they are issued (which is -between two and four times a year.) - -Regularly, we will send you a new version of an Lisps/Emacs, Languages, -Utilities, or X Window System (X11R6) Required tape or the Source CD-ROM. -The MIT Scheme and X Window System Optional tapes are not changed often -enough to warrant quarterly updates. We do not yet know if we will be -offering subscriptions to the Compiler Tools Binaries or our new CD-ROMs. - -Since Emacs 19 is on the Lisps/Emacs Tape and the Source CD-ROM, a -subscription to either is an easy way to keep current with Emacs 19 as it -evolves. - -A subscription is an easy way to keep up with the regular bug fixes to the X -Window System. We update the X11R6 Required tape as fixes and patches are -issued throughout the year. Each new edition of the *Note Source Code -CD-ROMs::, also has updated sources for the X Window System. - -Please note: In two cases, you must pay 4 times the normal shipping required -for a single order when you pay for each subscription. If you're in Alaska, -Hawaii, or Puerto Rico you must add $20.00 for shipping for each -subscription. If you're outside of U.S., Canada, and Puerto Rico, you have -to add $80.00 for each subscription. See "Unix and VMS Software" & "Shipping -Instructions" on the *note Free Software Foundation Order Form::.. - - - -The Deluxe Distribution -*********************** - -The Free Software Foundation has been asked repeatedly to create a package -that provides executables for all of our software. Normally we offer only -sources. In addition to providing binaries with the source code, the Deluxe -Distribution includes a complete set of our printed manuals and reference -cards. - -The FSF Deluxe Distribution contains the binaries and sources to hundreds of -different programs including GNU Emacs, the GNU C Compiler, the GNU Debugger, -the complete X Window System, and all the GNU utilities. - -We will make a Deluxe Distribution for any machine, with any operating -system. We will send someone to your office to do the compilation, if we -can't find a suitable machine close to us! However, we can only compile the -programs that already support your chosen machine and system - porting is a -separate matter (if you wish to commission a port, see the GNU Service -Directory, details in *Note Free Software Support::). Compiling all these -programs take time; a Deluxe Distribution for an unusual machine will take -longer to produce then one for a common machine. Please contact the FSF -office if you have any questions. - -We supply the software in one of these tape formats in Unix `tar' format: -1600 or 6250bpi 1/2in reel, Sun DC300XLP 1/4in cartridge - QIC24, -Hewlett-Packard 16-track DC600HC 1/4in cartridge, IBM RS/6000 1/4in cartridge -- QIC 150, Exabyte 8mm cartridge, or DAT 4mm cartridge. If your computer -cannot read any of these, please contact us to see if we can handle your -format. - -The manuals included are one each of the `Bison', `Calc', `Gawk', `GNU C -Compiler', `GNU C Library', `GDB', `Flex', `GNU Emacs Lisp Reference', -`Programming in Emacs Lisp: An Introduction', `Make', `Texinfo', & `Termcap' -manuals; six copies of the `GNU Emacs' manual; and a packet of ten reference -cards each for GNU Emacs, Bison, Calc, Flex, & GDB. Every Deluxe -Distribution also includes a copy of the latest editions of our CD-ROMs -(including the MS-DOS CD & the Debian GNU/Linux CD when they are available) -that contain sources of our software & compiler tool binaries for some -systems. The MS-DOS CD is in ISO 9660 format. The other CDs are in ISO 9660 -format with Rock Ridge extensions. - -The price of the Deluxe Distribution is $5000 (shipping included). These -sales provide enormous financial assistance to help the FSF develop more free -software.

These can be prevented -by setting the flag in tm.h that requires strict alignment. - -4) Scaled indexing in an insn following an insn that has a read-write -operand in memory.

However, is this includes "addd 5,-4(fp)" -then there is room for disaster.

For example, it is -almost always faster to double a quantity by adding it to itself than -by shifting it by one, even if that quantity is deep in memory. The -MOVM instruction has a 20-cycle setup time, after which it moves data -at about the speed that normal moves would. It is also faster to use -address generation instructions than shift instructions for left -shifts less than 4.

The current implementation -of GCC manifests 68000-ist thinking, where bitfields are extracted -into a register, and automatically sign/zero extended to fill the -register. See comments in ns32k.md around the "extzv" insn for more -details. - - -It should be noted that while the NS32000 family was designed to -provide odd-aligned addressing capability for multi-byte data (also -provided by the 68020, but not by the 68000 or 68010), many machines -do not opt to take advantage of this. For example, on the sequent, -although there is no advantage to long-word aligning word data, shorts -must be int-aligned in structs. This is an example of another -machine-specific machine dependency. - - -Because the ns32032 is has a coherent byte-order/bit-order -architecture, many instructions which would be different for -68000-style machines, fold into the same instruction for the 32032. -The classic case is push effective address, where it does not matter -whether one is pushing a long, word, or byte address.

The file g77spec.c contains the g77-specific source code -for the `g77' command only -- this just forms a variant of the `gcc' -command, so, just as the `gcc' command itself does not contain -the C front end, the `g77' command does not contain the Fortran front -end (FFE). The FFE code ends up in an executable named `f771', which -does the actual compiling, so it contains the FFE plus the gcc back end -(the latter to do most of the optimization, and the code generation). - -The file parse.c is the source file for main() for a stand-alone FFE and -yyparse() for f771. (Stand-alone building of the FFE doesn't work these days.) -The file top.c contains the top-level FFE function ffe_file and it (along -with top.h) define all ffe_[a-z].*, ffe[A-Z].*, and FFE_[A-Za-z].* symbols. -The file fini.c is a main() program that is used when building the FFE to -generate C header and source files for recognizing keywords. The files -malloc.c and malloc.h comprise a memory manager that defines all -malloc_[a-z].*, malloc[A-Z].*, and MALLOC_[A-Za-z].* symbols.

Destructors are encoded as two leading underscores -separated by either a period or a dollar sign, depending on the -capabilities of the local host, followed by the encoded name. For -example, the destructor @samp{foo::~foo} is encoded as @samp{_$_3foo}. - -@item -Virtual tables are encoded with a prefix of @samp{_vt}, rather than -@samp{__vtbl}. The names of their classes are separated by dollar signs -(or periods), and not encoded as normal: the virtual table for -@code{foo} is @samp{__vt$foo}, and the table for @code{foo::bar} is -named @samp{__vt$foo$bar}. - -@item -Static members are encoded as a leading underscore, followed by the -encoded name of the class in which they appear, a separating dollar sign -or period, and finally the unencoded name of the variable. For example, -if the class @code{foo} contains a static member @samp{bar}, its -encoding would be @samp{_3foo$bar}. - -@item -@sc{gnu} C++ is not as aggressive as other compilers when it comes to always -generating @samp{Fv} for functions with no arguments.

However, the values for -@var{n} and @var{y} begin at zero with @sc{gnu} C++, whereas the -@sc{arm} describes them as starting at one.

For example, a function like the -following produces a syntax error on the closing @samp{)} of the -definition of the function @code{f}: - -@smallexample -template <class T> class A @{ public: T x; class Y @{@}; @}; -template <class X> int f (A<X>::Y y) @{ @dots{} @} -@end smallexample - -@cindex @code{inline} and function templates -@cindex function templates and @code{inline} -@item -If you declare an @code{inline} function using templates, the compiler -can only inline the code @emph{after} the first time you use -that function with whatever particular type signature the template -was instantiated. - -Removing this limitation is akin to supporting nested function -definitions in @sc{gnu} C++; the limitation will probably remain until the -more general problem of nested functions is solved. - -@item -All the @emph{method} templates (templates for member functions) for a -class must be visible to the compiler when the class template is -instantiated. -@end itemize - -@node Class templates -@section Limitations for class templates - -@cindex class template limitations -@ignore -FIXME!! Include a comprehensible version of this if someone can explain it. - (Queried Brendan and Raeburn w/full orig context, 26may1993---pesch) - - [RHP: I don't understand what the following fragment refers to. If it's - the "BIG BUG" section in the original, why does it say "overriding class - declarations" here when the more detailed text refers to *function* - declarations? Here's the fragment I don't understand:] - there are problems with user-supplied overriding class declarations (see - below). -@end ignore - -@itemize @bullet -@ignore -@cindex static data, not working in templates -@item -Templates for static data in template classes do not work. -Currently, you must initialize each case of such data -individually. -@c FIXME!! Brendan to see if still true. -@c ANSWER: This section presumes that it's incorrect to have to -@c initialize for each type you instantiate with. It's not, it's the -@c right way to do it. -@end ignore - -Unfortunately, individual initializations of this sort are likely to be -considered errors eventually; since they're needed now, you might want to -flag places where you use them with comments to mark the need for a -future transition. - -@cindex nested type results vs templates -@item -Member functions in template classes may not have results of nested -type; @sc{gnu} C++ signals a syntax error on the attempt. The following -example illustrates this problem with an @code{enum} type @code{alph}: - -@smallexample -template <class T> class list @{ - @dots{} - enum alph @{a,b,c@}; - alph bar(); - @dots{} -@}; - -template <class T> -list<int>::alph list<int>::bar() // @i{Syntax error here} -@{ -@dots{} -@} -@end smallexample - -@cindex preprocessor conditionals in templates -@cindex conditionals (preprocessor) in templates -@item -A parsing bug makes it difficult to use preprocessor conditionals within -templates. For example, in this code: - -@smallexample -template <class T> -class list @{ - @dots{} -#ifdef SYSWRONG - T x; -#endif - @dots{} -@} -@end smallexample - -The preprocessor output leaves sourcefile line number information (lines -like @samp{# 6 "foo.cc"} when it expands the @code{#ifdef} block. These -lines confuse the compiler while parsing templates, giving a syntax -error. - -If you cannot avoid preprocessor conditionals in templates, you can -suppress the line number information using the @samp{-P} preprocessor -option (but this will make debugging more difficult), by compiling the -affected modules like this: - -@smallexample -g++ -P foo.cc -o foo -@end smallexample - -@cindex parsing errors, templates -@item -Parsing errors are reported when templates are first -@emph{instantiated}---not on the template definition itself. In -particular, if you do not instantiate a template definition at all, the -compiler never reports any parsing errors that may be in the template -definition. -@end itemize - -@node Template debugging -@section Debugging information for templates - -@cindex templates and debugging information -@cindex debugging information and templates -Debugging information for templates works for some object code formats, -but not others.
