1 This is tcsh version 6.10. Tcsh is a version of the Berkeley
2 C-Shell, with the addition of: a command line editor, command and file
3 name completion, listing, etc. and a bunch of small additions to the
6 Tcsh has been ported to most unix variants, and can be tinkered to work
7 in unix systems that it has not ported yet. See the Ported file for
8 a more complete list of ported systems and in the config directory for
9 a configuration file that matches your system.
10 Tcsh also runs under VMS/POSIX and OS/2+emx; the OS/2 port is not
13 Feel free to use it. These changes to csh may only be included in a
14 commercial product if the inclusion or exclusion does not change the
15 purchase price, level of support, etc. Please respect the individual
16 authors by giving credit where credit is due (in other words, don't
17 claim that you wrote portions that you haven't, and don't delete the
18 names of the authors from the source code or documentation).
22 0) Try running "configure". If that works, goto step 6.
23 If you are using imake, try xmkmf and goto step 3.
24 If imake does not work, copy Makefile.std to Makefile.
26 1) Look at the Makefile and make sure that you are using the right
29 2) Copy the appropriate for your machine and OS config file from the
30 config subdirectory into config.h. Consult the file "Ported" for
31 settings known to work on various machines. If you are trying to
32 compile tcsh on a machine for which there is no config file yet,
33 you will need to create a config file using as a template one of
34 the supplied ones. If you get tcsh working on a new machine, I'd
35 appreciate a copy of the config file plus additional information
36 about the architecture/OS. If you are creating a new config file,
37 look very hard at BSDJOBS, BSDSIGS, and BSDTIMES if you are running
38 a non-BSD machine. For vanila SysV, these would all be #undef-ed,
39 but others may vary (such as A/UX or HPUX). On a pyramid, compile
40 in the UCB universe even if you are running under the ATT universe
41 usually; it will work anyway, and you get job control for free.
43 3) Look at config_f.h, and enable or disable any features you want.
44 It is configured the way I like it, but you may disagree.
45 If you do not have NLS, then locale.h will not be found. Undefine it
46 and things should work ok. On the other hand, if you have NLS you
47 might as well use it...
49 4) Look at host.defs to make sure that you have the right defines to set
50 the environment variables "HOSTTYPE", "MACHTYPE", "OSTYPE" and
51 "VENDOR" correctly. If you need to make changes, PLEASE SEND THEM
54 5) You may want to adjust the TCSH_BINDIR and TCSH_MANDIR entries in
55 the Makefile. These are the directories that tcsh, and the tcsh.1
56 man entry will be placed in when you do a "make install" and "make
57 install.man" respectively. If you decide to install tcsh somewhere
58 other than in /usr/local/bin/tcsh, you should #define _PATH_TCSHELL
59 "/your/installation/directory/tcsh" in pathnames.h.
61 6) If you've changed any of the configuration variables you may need
66 8) Read the documentation while you are waiting. The file tcsh.man
67 is in standard [nt]roff -man format. If you like, you can run the
68 tcsh.man2html script (requires Perl) to generate an HTML version of
69 the manpage which you can read with Mosaic, lynx or other HTML browser.
71 9) Test tcsh by typing ./tcsh to see that it has compiled correctly.
72 The history command should give a time stamp on every entry.
73 Typing normal characters should echo each exactly once. Control-A
74 should put the cursor at the beginning of the input line, but after
75 the prompt. Typing characters after that should insert them into
76 the line. If you have job control make sure that stopping and
77 restarting jobs works. Make sure you can ^C in the middle of the
78 input line. Also make sure that pipelines work correctly and there
79 are no races. Try 'echo | cat | cat | cat | cat | more' a couple of
80 times. If you have job control, try this command in the background
81 and bring it in the foreground when it stops for tty output. Also
82 make sure that the ioctl() modes are preserved. Get into vi, enter
83 and exit input mode and suspend it, background it and foreground it
84 again. After all that, lastly make sure that the tty process group
85 manipulation is happening correctly. Try ftp to some host. If your
86 passwd appears on the screen, you have lost /dev/tty. Otherwise
89 10) Once satisfied that tcsh is working correctly, complete the installation
90 by typing "make install" to install the binary, and "make install.man" to
91 install the documentation. Don't forget to look at complete.tcsh for
96 12) PLEASE send any bug reports (and fixes), code for new features,
97 comments, questions, etc. (even flames) to:
104 ***************************************************************************
106 On sysv versions < 3.0 (not hpux) Doug Gwyn's public domain directory
107 manipulation library has to be installed. This library is available
108 for anonymous ftp from prep.ai.mit.edu:/pub/gnu/dirent.tar.Z
109 If the network is not installed, then there is a gethostname()
110 routine is tc.os.c, enabled by defining NEEDgethostname
112 ***************************************************************************
114 On BSDreno, in ttyname() closedir() is called twice and so the same
115 pointer gets free'd twice. tcsh's malloc is picky and it prints an
116 error message to that effect. If you don't like the message:
118 1. Apply the following patch:
120 *** /usr/src/lib/libc/gen/ttyname.c.orig Fri Jun 1 17:17:15 1990
121 --- /usr/src/lib/libc/gen/ttyname.c Tue Oct 29 16:33:12 1991
124 if (stat(buf, &sb2) < 0 || sb1.st_dev != sb2.st_dev ||
125 sb1.st_ino != sb2.st_ino)
133 Or: Comment the error printing out in tc.alloc.c
134 Or: Compile -DSYSMALLOC

141 Tcsh has been ported to minix by Scott Krotz (krotz@honey.rtsg.mot.com).
142 Unfortunately the minix sed is broken, so you'll have to find a way to
143 make tc.const.h, sh.err.h, ed.defns.h which are automatically generated.
144 The easiest way to create them is to make a copy from unix, copying
145 minix to config.h, and then 'make sh.err.h tc.const.h ed.defns.h'
147 The OS/dependent files are in mi.termios.h, mi.wait.h, mi.varargs.h
149 You will get some warnings, but dont worry about them, just ignore
150 them. After tcsh has compiled and the gcc binary is converted to a
151 minix binary, remember to chmem it to give it more memory - it will
152 need it! How much you need depends on how many aliases you have, etc..
153 Add at least 50000 to it.
155 One last thing. You might have to make some links for include files so
156 that they are in the directories that tcsh is expecting while compiling.
157 I forget if I had to do this or not, but it should be fairly easy to sort
158 out. If it cant find any include files this is probably the reason.
160 If you have any problems, please tell me. I can be contacted through
163 krotz@honey.rtsg.mot.com
165 I also read comp.os.minix on a regular basis, so a note there will get
170 ps. The termios functions are provided by Magnus Doell and Bruce Evans.
174 From: Bob Byrnes <byrnes@ee.cornell.edu>
176 This is for minix 1.5 (straight out of the box from P-H) plus the i386
177 patches from Bruce Evans.
179 I cross-compiled on a Sun using gcc 2.1 with a target of i386-bsd
180 (using the minix include files instead of the bsd versions), and then
181 linked the resulting object files with similarly compiled crtso.o and
182 libc.a on vax (little endian) using a hacked version of ld which I put
183 together to generate minix executables instead of bsd a.out format.
186 I compiled with -O2 -Wall ... So far I haven't noticed any problems
189 In case anyone is contemplating compiling tcsh with bcc (Bruce Evan's
190 i386 compiler that comes with the minix386 upgrade package), don't bother.
191 It is some serious bugs that kill tcsh when compiled for 16-bit characters.
192 I can provide more details of bugs that I noticed for brave souls who want
193 to try, but it would be hard (and why bother if you can get gcc?).
195 I can make the binary available to anyone who wants it (for example people
196 who can't get access to a cross-compiling environment, and who don't yet
197 have gcc running under minix).
