AAARRRRGGGGHHH!!!
After getting the X11R4 release, complete with fixes 1-11, I tried
to compile it for my SparcStation 4.0.3.
Hurrah! Everything compiled!
I typed "xinit", and great!! I got the grey screen and X cursor, along with
the xterm window.
I tried the TMW manager, and there my joys ended. I got:
xinit: connection to X server lost.
and the world shut down (i.e. I was logged off).
[...]
I know zilch about the Xsun code; could someone please tell me
what I can do to fix this?
When I compiled X11R4 the first time on a Sparc with gcc, I had
exactly the same problem. Even if I only tried to start xlogo, the
server crashed. I don't know the real reason for the problem, but I
fixed it by saying
#define ServerCcCmd cc
#define ServerCDebugFlags -O
in mit/config/site.def (and another make World :-)). I tried gcc
without optimization and gcc -g too, but with the same bad results.
With cc we had no problems with the server. On our Sun 3/50's is it
possible to use gcc without any problem.
If anyone knows, how to use gcc for compiling the server, please let
me know.
Thanks, Swen

With that incompatibility the X server will break when it tries to access the rgb database with the ndbm functions. There is a few solutions to that problem: 1) use sun standard cc compiler with -O2 to get the maximum optimization out of it. 2) If you have the source code to the dbm library then just recompile it with the gcc compiler. 3) You can use the gnu gdbm library which provide ndbm functionality but the database file produced has different format. 4) find out all the calls to ndbm functions in the server code and compile them with the standard cc compiler.

Err, umm: 1) "-O" is equivalent to "-O2" in SunOS 4.x on a SPARC-based machine; 2) "the maximum optimization" is "-O4", although, to quote the manual page, "neither -O3 nor -O4 should be used when compiling either device drivers, or programs that modify external variables from within signal handlers;" I don't know if that'll break any X11 code or not. BTW, if you have a 68K-based Sun and are running 4.0[.x], it might be interesting to see what performance difference results from compiling with "-O2" ("-O" is equivalent to "-O2" in 4.1 on 68K-based machines); it worked when I tried it, but I didn't do any performance comparison.

I have compiled the entire R4 (mit tape) with -O4 on my Sun SS1; the only gotcha was MenuButton.c in the Athena widgets, which broke the optimizer and had to be "hand" compiled at -O2. I have over a month now, and nothing has broken yet. kaleb@mars.jpl.nasa.gov Jet Propeller Labs Kaleb Keithley spelling and grammar flames > /dev/null
