[gentoo-user] In search for a undeclared identifier...

[meino.cramer]

Hi,

I try to build the developper branch of a software project,
which is not in Gentoo.

This works a longer time.

Now the compilatino process aborts with

glmodule.c:926: error: 'glActiveTexture' undeclared (first use in this function)
.

Sounds somehow OpenGL-related:
I am using a nVidia Corporation GeForce 7600 GT with NVidia-drivers
and eselected opengl. Since Blender, which uses OpenGL a lot runs fine
and is also build each day from developper sources...

Does anyone know to what glActiveTexture belongs to?
And where I can buy one for my Linux box ;)

Thank you very much in advance for any helpful hint !

Best regards
mcc

On my system it's in /usr/include/GL/glew.h header, which belongs to
media-libs/glew, so you probably need to have it installed.

My bad, I've misread grep results. It really is
in /usr/include/GL/glext.h.
And that file should be symlink created by "eselect opengl" with
source belonging either to media-libs/mesa or nvidia drivers.

If source file include lines are correct, you might want to try
re-emerging nvidia drivers and eselect'ing them.

The header file is probably installed correctly, since the compiler's 
error complains about an undeclared identifier rather than a 
non-existent header ("error: GL/glext.h: No such file or directory").

Hi,

thank for the help ! :o)

Currently I cannot decide whether everything is setup correctly on my
box:

ls -l /usr/include/GL/glext.h

gives me

lrwxrwxrwx 1 root root 40 2009-08-14 04:34 /usr/include/GL/glext.h -> //usr//lib/opengl/global/include/glext.h

which looks linke pointing neither to mesa nor to nvidia -- at least
for my blurred eyes.

Would it be possible to post a correctly set link for comparison?

Thanks a lot in advance!
mcc

PS: And thank you for the tip: Now I can save my money for better
    things as DVDs of "Raiders of the lost identifier" (Indiana Gnu).

You didn't follow the instructions.  "eselect opengl" will tell you.  To 
make sure, do "eselect opengl set x11; eselect opengl set nvidia".

But as I already wrote in another post, this looks like a bug in the 
application you're trying to build.

Before I posted, I did a 

    eselect opengl set nvidia

but from the result I can not tell, whether its pointing
to the correct file.
The only proof I have is the command I gave.

You don't need to buy anything.  All you need is to tell the person who 
wrote glmodule.c to go fix the code :)

It's probably a matter of:

#define GL_GLEXT_PROTOTYPES
#include <GL/glext.h>
