I compiled 64 bit mesa now with gcc 3.4.2 from sunfreeware and it crashes, too
but with other errors.

./gears
One time I get an assertion:

Assertion failed: a[j].inputstride == vptr->stride, file tnl/t_vertex.c, line 382

Maybe the memory has a wrong alignment and trying to read from this misaligned
memory sends
an bus error.

running the ray demo I got the same segmentation fault like mesa compiled with

I'll add the sunos5-64-gcc config.

For the mklib script we need a test to determine if the object files are 32 or
64-bit, then pass the right options to the linker.  For Linux we parse the
output of 'file file.o'.

Could you send me the output of running 'file' on both a 32 and 64-bit object
file?  I'll use that info to update the mklib script.

As for the runtime problems, you might be able to get more debug info if you
recompiled without -O3.  If things run OK w/out -O3 it might be a compiler bug.

Thank you for adding the the sunos5-64-gcc config.

The output of file <object file> vary a little bit depending on
the compiler flags
32 Bit mit gcc CGLAGS -mcpu=ultrasparc -mv8plus -mvis
or at least -mcpu=ultrasparc
=>
file ./progs/xdemos/pbutil.o
./progs/xdemos/pbutil.o:        ELF 32-bit MSB relocatable SPARC32PLUS Version
1, V8+ Required, UltraSPARC1 Extensions Required

64 Bit CFLAGS at least -m64 -mcpu=ultrasparc
=>
file ./progs/xdemos/pbutil.o
./progs/xdemos/pbutil.o:        ELF 64-bit MSB relocatable SPARCV9 Version 1,
UltraSPARC1 Extensions Required

But you can compile binaries for old 32 Bit only sparc machines 
(might be 10 years old)
but the default of gcc on sun (without mcpu option)
hallo.o:        ELF 32-bit MSB relocatable SPARC Version 1

For 64 Bit without mpcu
hallo.o:        ELF 64-bit MSB relocatable SPARCV9 Version 1

For better supporting the solaris platform it would be the best thing if
you try to compile it on a old cheap ultrasparc machine. E.g. an ultra5/10
with about 400 MHz could be bought for about less than 100 $.
With a 440 MHz prozessor it's even a nice machine that can play DVDs with xine
...

I'll try to compile mesa without -O3 option and tell you my results but
for further more complicate activities it would be the best thing if one
Mesa developer can do it on a sun on his own.

OK, I think I've got the mklib script updated.  Can you try the version in cvs
at http://webcvs.freedesktop.org/mesa/Mesa/bin/

Hello Brian,
thank you for the changed configs file for solaris (sunos5-64-gcc).
To run make sunos5-64-gcc I've to correct the Makefile first:

/opt/sfw/bin/cvs diff Makefile
Index: Makefile
===================================================================
RCS file: /cvs/mesa/Mesa/Makefile,v
retrieving revision 1.63
diff -r1.63 Makefile
128a129
> sunos5-64-gcc \

So, please add this line to the main Makefile.
(Does anybody of the Mesa developer team has access 
to an old cheap ultrasparc solaris system? That could make
bug fixing more easy)

The build stopped at:

OK, I've added sunos5-64-gcc to the toplevel Makefile.

The src/mesa/sparc/glapi_sparc.S file wasn't getting regenerated so it was
missing those three functions you listed.  Should be OK now.

I suppose having an old sparc machine would be handy, but I've already got at
least 10 computers in my office.

If there's ever a need Brian - give me a shout. I've got an Ultra 60 here that
you can either ssh into or I'll build test.

Thank you Alan, I hope that could help solving the solaris problem.
I hope you've an installed at least gcc 3.4.2 on that machine, too.

The cvs version of last weak compiled fine but still crashed for 64 Bit on
Solaris 9 (ultrasparc).

This bug has not been updated in four years.  Closing.
