Question:       Anyone installed compress on SCO Xenix yet?

Problem:        Compress is not doing anything, it runs but terminated
                with the file unchanged.  There are some #ifdef M_XENIX
                in the code but it may not be tested.

Environment:    IBM-PC/AT runs SCO Xenix version 2.1.3
                compress version 4.0 85/07/30 12:50:00 joe Release

Build History:  $ cc -s -o compress compress.c
                /bin/ld: Common area longer than 65535 bytes

                $ cc -Ml -s -o compress compress.c    #use large model
                $ ln compress uncompress
                $ ln compress zcat
                There was no error in any of the above 3 steps.

I have both 12 bit (small model) and 16 bit (large model with M_XENIX).
The large model compress chokes on some files (as does a version compiled
under MicroPort), but seems to uncompress 16 bit news feeds OK.  Be careful
of Microsoft "unsigned" right shifts that aren't unsigned.

If you want the distributed version of compress to compile without error

     $ cc -Dpcxt -ocompress compress.c

This will give you a working version of compress, unfortunately it will
only have the capability of handling 12-bit compression.

I have a version of compress that I hacked to work with 16-bit compression.
If there is sufficient interest, I can post this.

I have the full functionality of compress working on SCO. I got
the fixes from someone on the net, I think at SCO. I would be
willing to mail to a few people, but my mailer get upset if I
mail too much, and I might have to post it or put it on my BBS.
It's in small model with huge extensions. Source is ~40K without
the atob, etc, which comes with the package as posted.

NOTE: I doubt like hell that this version will run under any
other version.

Sorry to post this, but the return path from here is quite unlikely to work.

Why not post it to this group, or mail it to me, and I can check it on
the one file I have that chokes the current large model compress.  I think
the problem arises when trying to compress binary files.  Try to compress
a copy of /xenix, then uncompress it to see if 1) something core dumps 2)
the resulting file is modified.

1. Mount xenix /u system under SCO 5.02 and WD network card with Xenix

I have xenix and SCO 5.02 on same harddrive and would like to use
xenix filesystem under UNIX! I followed directions found in one of the
articles
on sosco and got message
could not stat device.
DOS is 1st partition, Xenix is 2nd and UNIX is 3rd partition.
do I need change numbers on mknod command?

Second question is on WD 8003EBT NIC.
It works OK under xenix right after mkdev wdn and mkdev tcp. If I reboot
into DOS and back again in Xenix, it stops working. Then I delete it.
redo mkdev wdn;mkdev tcp and works OK. I am experiencing similar
under SCO UNIX. Is there problem with card initialization after reboots.
Thanks for help.
