    This is tcsh version 6.20.00.  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 doesn't work, goto step 1.
        Run "./configure --help" to see possible options.  After running
        configure, goto step 3.

    1)  Otherwise copy Makefile.std to Makefile. 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 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.

    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 DESTBIN and DESTMAN 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.

    On sysv versions < 3.0 (not hpux) Doug Gwyn's public domain directory
    manipulation library has to be installed. This library is available
    for anonymous ftp from prep.ai.mit.edu:/pub/gnu/dirent.tar.Z
    If the network is not installed, then there is a gethostname()
    routine is tc.os.c

    ***************************************************************************

    On BSDreno, in ttyname() closedir() is called twice and so the same
    pointer gets free'd twice. tcsh's malloc is picky and it prints an
    error message to that effect. If you don't like the message:

    1. Apply the following patch:

    Tcsh has been ported to minix by  Scott Krotz (krotz@honey.rtsg.mot.com).
    Unfortunately the minix sed is broken, so you'll have to find a way to
    make tc.const.h, sh.err.h, ed.defns.h which are automatically generated.
    The easiest way to create them is to make a copy from unix, copying
    minix to config.h, and then 'make sh.err.h tc.const.h ed.defns.h'

    The OS/dependent files are in mi.termios.h, mi.wait.h, mi.varargs.h

    You will get some warnings, but dont worry about them, just ignore
    them.  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
