'GL_TEXTURE0_ARB' : undeclared identifier
Author
Hi, this is my first time on the forum and I have a quick question...I am using SDL/OpenGL on MS Visual Studio .NET and I get this:
''glActiveTextureARB'': identifier not found, even with argument- dependent lookup
what is this? I know all my libraries are linked cuz i have written other code w/ no problems...any ideas?
Just a stab in the dark, because you don''t explain your code much...
OpenGL uses an extension mechanism. Since no one ever updates the window''s OpenGL library, the only way to access the newer features and features different cards support is through extensions. glActiveTextureARB is one such extension. Go to NeHe, he has tutorials on using extensions. He even has a tutorial on Multitexturing which is what I am assuming you are doing.
I hope this helps, if not, explain your problem better.

Well one option is to download the GLee library (see sig). It allows you to just do

#include <GL\Glee.h>...gleeInit(); //in your setup code...if (GLEE_ARB_multitexture) //check for multitexture extension { glActiveTextureARB(...);}//OR alternatively, if you have an OpenGL 1.3 cardif (GLEE_VERSION >= 1.3){ glActiveTexture(...);}____________________________________________________________

I should probably also mention that the forum FAQ has a section on extensions, which includes a link to Dave Astle''s article on the subject.
