hello all,
i'm trying to compile qt4, and it fails with:
g++ -fno-exceptions -Wl,-R,/usr/local/Trolltech/Qt-4.4.3/lib 
-Wl,-R,/usr/local/Trolltech/Qt-4.4.3/lib -Wl,-R,/opt/csw/lib -o

Undefined                       first referenced
  symbol                             in file

after searches, i found that these variables come with Sun OpenGL:
mombasa-root% nm /usr/lib/libGL.so | grep sunOgl
[6431]  |   1767764|       4|OBJT |GLOB |0    |20     |sunOglCurPrimTablePtr
[5476]  |   1790640|       4|OBJT |GLOB |0    |23     |sunOglCurrentContext
[2164]  |   1767908|       4|OBJT |LOCL |2    |20     |sunOglPostFinish
[2108]  |   1767904|       4|OBJT |LOCL |2    |20     |sunOglPostFlush

And the qt4 configure takes CSWmesa into account, unfortunately, it 
doesn't contains:
mombasa-root% nm /opt/csw/lib/libGL.so | grep sunOgl

I suppose the problem only happens on sparc machines, with Sun OpenGL.
A solution could be to disable OpenGL features?
Is there another solution?

thanks in advance,
