Hi
I've tried to use multitexture extension of opengl with gnat,
but this extension isn't in the list returned by glGetString.
However, with the same program in C, compiled with VC++,
the extensions si present.
Are the gnat library too old ? If it's so, where can I find a newer one ?
Eddy

The GNAT distribution does not include an OpenGL library. So you must
have gotten the OpenGL library somewhere else.
What OS are you on?

I'm on Win 2K
There is a libopengl32.a in my Gnat/lib directory.
I though it was provided by the gnat.

A reasonable assumption :). Hmm. That file does appear in
GNAT/lib/win32 in my distribution; I did not look there the first
time, since you didn't say you were on Windows.
So now I get to ask; what version of GNAT do you have? The latest
public version is 3.14p; try upgrading to that.
I suspect libopengl32.a is simply a binding to the Win32 OpenGL DLL; I
don't see why it would return different results via C. Very odd.

DLL's are supposed to strive to be backward-compatable, to the extent of
fully supporting older interfaces. Perhaps the Ada bindings call into an
older interface than the C bindings he is using.

Unless the C version links against, say, the NVIDIA implementation.
