Tcsh is a version of the Berkeley +C-Shell, with the addition of: a command line editor, command and file +name completion, listing, etc. and a bunch of small additions to the +shell itself. + +Tcsh has been ported to most unix variants, and can be tinkered to work +in unix systems that it has not ported yet. See the Ported file for +a more complete list of ported systems and in the config directory for +a configuration file that matches your system. +Tcsh also runs under VMS/POSIX and OS/2+emx; the OS/2 port is not +complete yet. + +Feel free to use it. These changes to csh may only be included in a +commercial product if the inclusion or exclusion does not change the +purchase price, level of support, etc. Please respect the individual +authors by giving credit where credit is due (in other words, don't +claim that you wrote portions that you haven't, and don't delete the +names of the authors from the source code or documentation). + +To install tcsh: + +0) Try running "configure". If that works, goto step 6. + If you are using imake, try xmkmf and goto step 3. + If imake does not work, copy Makefile.std to Makefile. + +1) Look at the Makefile and make sure that you are using the right + compilation flags. + +2) Copy the appropriate for your machine and OS config file from the + config subdirectory into config.h. Consult the file "Ported" for + settings known to work on various machines. If you are trying to + compile tcsh on a machine for which there is no config file yet, + you will need to create a config file using as a template one of + the supplied ones. If you get tcsh working on a new machine, I'd + appreciate a copy of the config file plus additional information + about the architecture/OS. If you are creating a new config file, + look very hard at BSDJOBS, BSDSIGS, and BSDTIMES if you are running + a non-BSD machine. For vanila SysV, these would all be #undef-ed, + but others may vary (such as A/UX or HPUX). On a pyramid, compile + in the UCB universe even if you are running under the ATT universe + usually; it will work anyway, and you get job control for free. + +3) Look at config_f.h, and enable or disable any features you want. + It is configured the way I like it, but you may disagree. + If you do not have NLS, then locale.h will not be found. Undefine it + and things should work ok. On the other hand, if you have NLS you + might as well use it... + +4) Look at host.defs to make sure that you have the right defines to set + the environment variables "HOSTTYPE", "MACHTYPE", "OSTYPE" and + "VENDOR" correctly. If you need to make changes, PLEASE SEND THEM + BACK TO ME. + +5) You may want to adjust the TCSH_BINDIR and TCSH_MANDIR entries in + the Makefile. These are the directories that tcsh, and the tcsh.1 + man entry will be placed in when you do a "make install" and "make + install.man" respectively. If you decide to install tcsh somewhere + other than in /usr/local/bin/tcsh, you should #define _PATH_TCSHELL + "/your/installation/directory/tcsh" in pathnames.h. + +6) make + +7) Read the documentation while you are waiting. The file tcsh.man + is in standard [nt]roff -man format. If you like, you can run the + tcsh.man2html script (requires Perl) to generate an HTML version of + the manpage which you can read with Mosaic, lynx or other HTML browser. + +8) Test tcsh by typing ./tcsh to see that it has compiled correctly. + The history command should give a time stamp on every entry. + Typing normal characters should echo each exactly once. Control-A + should put the cursor at the beginning of the input line, but after + the prompt. Typing characters after that should insert them into + the line. If you have job control make sure that stopping and + restarting jobs works. Make sure you can ^C in the middle of the + input line. Also make sure that pipelines work correctly and there + are no races. Try 'echo | cat | cat | cat | cat | more' a couple of + times. If you have job control, try this command in the background + and bring it in the foreground when it stops for tty output. Also + make sure that the ioctl() modes are preserved. Get into vi, enter + and exit input mode and suspend it, background it and foreground it + again. After all that, lastly make sure that the tty process group + manipulation is happening correctly. Try ftp to some host. If your + passwd appears on the screen, you have lost /dev/tty. Otherwise + everything is fine. + +9) Once satisfied that tcsh is working correctly, complete the installation + by typing "make install" to install the binary, and "make install.man" to + install the documentation. Don't forget to look at complete.tcsh for + useful completions... + +10) Enjoy. + +11) PLEASE send any bug reports (and fixes), code for new features, + comments, questions, etc. (even flames) to: + + The tcsh mailing list + tcsh@mx.gw.com + +Various: + +*************************************************************************** + +On sysv versions < 3.0 (not hpux) Doug Gwyn's public domain directory +manipulation library has to be installed.

After tcsh has compiled and the gcc binary is converted to a +minix binary, remember to chmem it to give it more memory - it will +need it! How much you need depends on how many aliases you have, etc.. +Add at least 50000 to it. + +One last thing. You might have to make some links for include files so +that they are in the directories that tcsh is expecting while compiling. +I forget if I had to do this or not, but it should be fairly easy to sort +out. If it cant find any include files this is probably the reason. + +If you have any problems, please tell me. I can be contacted through +e-mail at: + +krotz@honey.rtsg.mot.com + +I also read comp.os.minix on a regular basis, so a note there will get +my attention also. + +Have fun! + +ps. The termios functions are provided by Magnus Doell and Bruce Evans. + Thanks, guys! + + +From: Bob Byrnes <byrnes@ee.cornell.edu> + +This is for minix 1.5 (straight out of the box from P-H) plus the i386 +patches from Bruce Evans. + +I cross-compiled on a Sun using gcc 2.1 with a target of i386-bsd +(using the minix include files instead of the bsd versions), and then +linked the resulting object files with similarly compiled crtso.o and +libc.a on vax (little endian) using a hacked version of ld which I put +together to generate minix executables instead of bsd a.out format. +What a kludge ... + +I compiled with -O2 -Wall ... So far I haven't noticed any problems +with the optimizer. + +In case anyone is contemplating compiling tcsh with bcc (Bruce Evan's +i386 compiler that comes with the minix386 upgrade package), don't bother. +It is some serious bugs that kill tcsh when compiled for 16-bit characters. +I can provide more details of bugs that I noticed for brave souls who want +to try, but it would be hard (and why bother if you can get gcc?). + +I can make the binary available to anyone who wants it (for example people +who can't get access to a cross-compiling environment, and who don't yet +have gcc running under minix). + + +*************************************************************************** + +If your compiler cannot handle long symbol names, add + +#include "snames.h" + +to your config.h file + + -- Christos Zoulas + christos@zoulas.com + |
