If your system does not understand ANSI/ISO C -syntax (i.e., if you have a K&R C compiler), compile xsum.c with --DKR_headers. (Eventually this will also be required of the f2c -source proper.) - -On non-Unix systems where files have separate binary and text modes, -you may need to "make xsumr.out" rather than "make xsum.out". - -If (in accordance with what follows) you need to modify the makefile -or any of the source files, first issue a "make xsum.out" (or, if -appropriate, "make xsumr.out") to check the validity of the f2c source, -then make your changes, then type "make f2c". - -The file usignal.h is for the benefit of strictly ANSI include files -on a UNIX system -- the ANSI signal.h does not define SIGHUP or SIGQUIT. -You may need to modify usignal.h if you are not running f2c on a UNIX -system. - -Should you get the message "xsum0.out xsum1.out differ", see what lines -are different (`diff xsum0.out xsum1.out`) and ask netlib to send you -the files in question "from f2c/src". For example, if exec.c and -expr.c have incorrect check sums, you would send netlib the message - send exec.c expr.c from f2c/src - -On some systems, the malloc and free in malloc.c let f2c run faster -than do the standard malloc and free. Other systems cannot tolerate -redefinition of malloc and free. If yours is such a system, you may -either modify the makefile appropriately, or simply execute - cc -c -DCRAY malloc.c -before typing "make". Still other systems have a -lmalloc that -provides performance competitive with that from malloc.c; you may -wish to compare the two on your system. - -On some BSD systems, you may need to create a file named "string.h" -whose single line is -#include <strings.h> -you may need to add " -Dstrchr=index" to the "CFLAGS =" assignment -in the makefile, and you may need to add " memset.o" to the "OBJECTS =" -assignment in the makefile -- see the comments in memset.c . - -For non-UNIX systems, you may need to change some things in sysdep.c, -such as the choice of intermediate file names. - -On some systems, you may need to modify parts of sysdep.h (which is -included by defs.h). In particular, for Sun 4.1 systems and perhaps -some others, you need to comment out the typedef of size_t. For some -systems (e.g., IRIX 4.0.1 and AIX) it is better to add -#define ANSI_Libraries -to the beginning of sysdep.h (or to supply -DANSI_Libraries in the -makefile). - -Alas, some systems #define __STDC__ but do not provide a true standard -(ANSI or ISO) C environment, e.g. do not provide stdlib.h . If yours -is such a system, then (a) you should complain loudly to your vendor -about __STDC__ being erroneously defined, and (b) you should insert -#undef __STDC__ -at the beginning of sysdep.h . You may need to make other adjustments. - -For some non-ANSI versions of stdio, you must change the values given -to binread and binwrite in sysdep.c from "rb" and "wb" to "r" and "w". -You may need to make this change if you run f2c and get an error -message of the form - Compiler error ... cannot open intermediate file ... - -On many systems, it is best to combine libF77 and libI77 into a single -library, say libf2c, as suggested in "readme from f2c". If you do this, -then you should adjust the definition of link_msg in sysdep.c -appropriately (e.g., replacing "-lF77 -lI77" by "-lf2c"). - -Some older C compilers object to - typedef void (*foo)(); -or to - typedef void zap; - zap (*foo)(); -If yours is such a compiler, change the definition of VOID in -f2c.h from void to int. - -For convenience with systems that use control-Z to denote end-of-file, -f2c treats control-Z characters (ASCII 26, '\x1a') that appear at the -beginning of a line as an end-of-file indicator. You can disable this -test by compiling lex.c with NO_EOF_CHAR_CHECK #defined, or can -change control-Z to some other character by #defining EOF_CHAR to -be the desired value. - -Please send bug reports to dmg@research.att.com . The old index file -(now called "readme" due to unfortunate changes in netlib conventions: -"send readme from f2c") will report recent changes in the recent-change -log at its end; all changes will be shown in the "changes" file -("send changes from f2c"). To keep current source, you will need to -request xsum0.out and version.c, in addition to the changed source -files. |
