Hello all,

I'm trying to run snowballs2. However, it failed while trying to load
libnel_drv_opengl.so with an undefined symbol glSetFenceNV.

I commented out all gl*Fence*NV symbols and now I have the following
error:

address@hidden:~/pub/NeL/code/snowballs2/client$ 
/usr/local/Installed/NeL/bin/snowballs 
INF 2967 client.cpp 145 : Starting Snowballs !
WRN 2967 path.cpp 440 : CPath::addSearchPath(data/pacs/, 0, 1): 'data/pacs/' is 
not found, skip it
WRN 2967 path.cpp 440 : CPath::addSearchPath(data/anims/, 0, 1): 'data/anims/' 
is not found, skip it
WRN 2967 dru.cpp 95 : when loading dynamic library 'libnel_drv_opengl.so': 
/usr/local/Installed/NeL/lib/libnel_drv_opengl.so: undefined symbol: 
glBindProgramNV
WRN 2967 common.cpp 390 : Exception will be launched: libnel_drv_opengl.so not 
found
Aborted

Like glSetFenceNV, glBindProgramNV symbol is not available in
/usr/lib/*GL* libraries neither in /usr/include/GL/*.h.

Notice also that those symbols are not defined in SGI latest glext.h
(http://oss.sgi.com/projects/ogl-sample/ABI/glext.h).

Notice also that Alexandre Courbot had the same problem as me
(http://www.nevrax.org/pipermail/nel/2001-October/000650.html). Apparently,
this has not been fixed.

Are those symbols standard OpenGL or Windows specific? I have missed
something?

Versions:
OpenGL implementation: Mesa 3 provided with XFree86 4.1.0.1
Linux 2.4.17, XFree 4.1.0.1,
OpenGL renderer string: Mesa DRI Rage128 20010405 AGP 1x x86/MMX
OpenGL version string: 1.2 Mesa 3.4.2


Thanks in advance for any help,
Best regards,
d.
