I want to find out how many texture units are supported by OpenGL implementation, so i write a program like this:


#include<windows.h>
#include<iostream.h>
#include<gl\gl.h>
#include<gl\glu.h>
#include<gl\glut.h>

void main()
{
	int mm;
	glGetIntegerv(GL_MAX_TEXTURE_UNITS,&mm);
	cout <<"mm = " << mm << endl;
}

but when i compiled i received the error message: error C2065: 'GL_MAX_TEXTURE_UNITS' : undeclared identifier i'm using VC6++ now. I really don't know that ! help me !!!

GL_MAX_TEXTURE_UNITS is defined in glext.h, you can download the extension header files from here:

Also, that won't work. You need to have created a valid OpenGL context (ie. display) before gl commands will work.
