PyOpenGL on Linux: MesaGL3: undefined: XFreePixmap

[John van der Koijk]

I'm stunned by the quality of (the people on) this newsgroup. Thanks!

    sr> First, let me say that I am extremely pleased that someone -

Glad to be of any help. ()

I've managed to mysteriously evade the XFreePixmap problem by juggling
with libraries, as suggested. However, probably due to conservation of
misery, the following happened:

linux01:~/uitpak/PyOpenGL-1.5.5/OpenGL/Demo/srenner $ python ./attention.py 
Traceback (innermost last):
  File "./attention.py", line 27, in ?
    from renderer import *
  File "./renderer.py", line 9, in ?
    from sropengl import *
  File "./sropengl.py", line 12, in ?
    from OpenGL.GLU import *
  File "/usr/lib/python1.5/site-packages/OpenGL/GLU/__init__.py", line 2, in ?
    from _glu import *
ImportError: /usr/lib/python1.5/site-packages/OpenGL/OpenGL/shared/linux2/\
_glumodule.so: undefined symbol: gluErrorString

So, I said:

$ objdump --syms /usr/lib/python1.5/site-packages/OpenGL/OpenGL/shared/\
linux2/_glumodule.so | grep tring
00002010 l     F .text  00000059 glu_ErrorString
00000000         *UND*  00000000 gluErrorString

and

$ grep gluErrorString *.c
_glumodule.c:  return Py_BuildValue("s", gluErrorString((GLenum)errCode));
_glumodule.c:  { "gluErrorString",      glu_ErrorString, 1},


for the record, the build process lead to

8<---------
gcc -fpic -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5 \
-DHAVE_CONFIG_H   -c ./_glumodule.c
gcc -shared -lc  _glumodule.o   -o _glumodule.so
gcc -fpic -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5 \
-DHAVE_CONFIG_H   -c ./_glutmodule.c
gcc -shared -lc  _glutmodule.o  -lglut  -o _glutmodule.so
8<---------

which sort of leaves me in a maze.

    sr> Perhaps you will have better luck with the next release, which
    sr> should be out within a few days.

Perhaps I should dig in and try to really understand this, but I'd
rather focus on my application...
