Description Roland Egger 2006-05-17 00:53:05 UTC
I compiled the last stable release 6.4.2 on Solaris 9 (sparc/ultrasparc)
for 32 bit. If I just run 
make sunos5-gcc
without changing sunos5-gcc everything builds fine but if I want to
build mangled mesa and add -DUSE_MGL_NAMESPACE to the defines in
It compiles and link the libraries libGL.so ... but with undefined symbols.
Afterwards I can't build the examples or any test program due to
the undefined symbols
make sunos5-gcc
stops with the followinf errors:
gcc -I../../include -Wall -O3 -g -fomit-frame-pointer -pipe -fPIC  -D_REENTRANT
-DUSE_XSHM -DUSE_MGL_NAMESPACE -DUSE_SPARC_ASM -std=c99 -ffast-math -I/usr/openw

I'll try the version 6.5 (Last development release) but I expect the same or
even worse errors. What is wrong here?
Comment 1 Roland Egger 2006-05-17 01:36:26 UTC
compiling of Mesa 6.5 has the same problem and has even problems without
"Function Name Mangling". The CVS version has problems with this
"mangled" version, too.
Comment 2 Brian Paul 2006-05-18 00:59:07 UTC
Does Solaris have the 'nm' program like Linux that lists the symbols in an
object file or library?  If so, I'd be curious to see 'nm libGL.so | grep

Are you sure you did a 'make realclean' after you added the -DUSE_MGL_NAMESPACE
Comment 3 Roland Egger 2006-05-18 23:14:07 UTC
Hi Paul,
of course Solaris has an nm ;)
Here's it's output

I think Alan offered you to compile Mesa on his sun.
That might be a good solution to get rid of the solaris

I removed all sources and made a clean build with
-DUSE_MGL_NAMESPACE and it has the errors like I described.
Can it be something special with the sun or the gnu ld?

Comment 4 Brian Paul 2006-05-19 00:07:04 UTC
It'll be a few days before I can get access to Alan's Solaris system.

In the mean time, could you run nm on the main/dispatch.o file?  Here's what I
get when I compile with -DUSE_MGL_NAMESPACE:

nm main/dispatch.o | grep Minmax
0000870f T mglGetMinmax
0000ab50 T mglGetMinmaxEXT
00008775 T mglGetMinmaxParameterfv
0000abb6 T mglGetMinmaxParameterfvEXT
000087cd T mglGetMinmaxParameteriv
0000ac0e T mglGetMinmaxParameterivEXT
000088d9 T mglMinmax
00008939 T mglMinmaxEXT
00008a3d T mglResetMinmax
00008a8f T mglResetMinmaxEXT

Comment 5 Roland Egger 2006-05-19 19:25:33 UTC
Hello Brian,
there are no symbols in dispatch.o.
Solaris nm shows:
nm ./src/mesa/main/dispatch.o

The GNU binutils nm shows:
egger@blade02 Mesa-6.4.2$ ~/opt/bin/nm -D ./src/mesa/main/dispatch.o
/export/home/egger/opt/bin/nm: ./src/mesa/main/dispatch.o: No symbols
egger@blade02 Mesa-6.4.2$ ~/opt/bin/nm ./src/mesa/main/dispatch.o
egger@blade02 Mesa-6.4.2$

If you won't get access to Alans machine maybe I can prepare an
access on my sun ultra5 at home (then I have to update ssh and change
the firewall rules ...)
I used the gcc from sunfreeware
and have tried it with a self compiled versions  gcc 3.4.4 and 4.0.2, too.
If you need a compiled gcc 3.4.4, 4.0.2 or a gdb 6.4 for
Solaris I can send you my compiled versions as tar archieves.
Then you could install it on a local folder.
Comment 6 Ian Romanick 2011-01-04 14:45:12 UTC
Are you still able to reproduce this on newer versions of Mesa?  A lot has happened in this area in the last 4+ years.
Comment 7 Ian Romanick 2015-11-30 23:46:13 UTC
I'm going to close this (very old bug).  I know that Mesa has built on Solaris since 2006.  I believe that there are other build problems, and those are tracked by other bugs (submitted by Vinson Lee).
