That's great news!

1. In the sense that "we" caught it quickly.
2. The NVIDIA Fermi (GTX480) extensions have
    turned up in the opengl.org repository...
    I have some patches ready and waiting for
    this moment. :-)

Tom,

Here is a patch that ought to resolve the build failures
in relation to the new extensions in the opengl.org registry.

Yes, the GetUniform* error is gone, but I get a new error:

  cc -O2 -Wall -W -Iinclude  -fPIC  -o src/glew.pic_o -c src/glew.c
  In file included from src/glew.c:32:

  src/glew.c:14284: error: expected declaration or statement at end of input
  make: *** [src/glew.pic_o] Error 1

This appears to happen because of a "blank" extension:

...
#endif /* GL_ARB_sample_shading */

/* ------------------------------------  ----------------------------------- */

#ifndef
#define  1

#define  GLEW_GET_VAR()

#endif /*  */

/* ------------------------ GL_ARB_seamless_cube_map ----------------------- */
...

line 3826 is the "#ifndef" line above.

Perhaps a parse error with one of the extension files?

Tom,

That seems to be due to patch making GL_ARB_sampler_objects
empty, rather than removing it completely.

Try this...

$ rm auto/core/GL_ARB_sampler_objects
$ make -C auto clobber all
$ make

[snip -- try rm'ing GL_ARB_sample_objects and rebuild]

Yep, that fixes it.

Hi all,

Unless there are any known show-stoppers, I'd like to spin
a GLEW 1.5.4 release.  This would add OpenGL 3.3, 4.0 and
the extensions for Fermi-generation Nvidia GPUs starting
with GTX480.

Nothing known / sounds good to me.
