Question Missing GL extensions


I think I must be doing something stupid.

I have installed the 3123 drivers on redhat 7.3.
X works fine. When I run the command "glxinfo", I get a huge list of supported extensions.

In my app, when I query the extension list via glGetString (GL_EXTENSIONS), the list is very short. I do get a reasonable looking renderer and gl version. Also, my GLX extension list is shorter (no pbuffers, for example).

When I run my app, it runs fast enough that I am pretty sure it must be using the nvidia drivers.

Here is what my application logs:

Renderer: "Quadro DCC/AGP/3DNOW!"

Extensions: "GL_ARB_multitexture GL_ARB_imaging GL_EXT_abgr GL_EXT_blend_color GL_EXT_blend_minmax GL_EXT_blend_subtract "

GL version: 1.3 ("1.3.1 NVIDIA 31.23")

GLX Extensions: "GLX_EXT_visual_info GLX_EXT_visual_rating GLX_EXT_import_context "

What am I missing?
