I''ve tried to compile some demos using multitexturing but have troubles with - glActiveTextureARB; - glMultiTexCoord2fARB; I''ve downloaded the NVIDIA OpenGL SDK 1.2 and updated my VisualC++ OpenGL stuff. But glActiveTextureARB and glMultiTexCoord2fARB still couldn''t be found. Finally I''ve put the extern void APIENTRY glActiveTextureARB (GLenum); extern void APIENTRY glMultiTexCoord2fARB (GLenum, GLfloat, GLfloat); into the code but at last the linker couldn''t find void __stdcall glMultiTexCoord2fARB(unsigned int,float,float)" (?glMultiTexCoord2fARB@@YGXIMM@Z) (blahblah..) Short, have troubles to use OpenGL V1.2... Any ideas what''s wrong? I hope someone could help me... Thanks in advance.

look for a header file on nVidia''s site called glExt.h. that is probably your problem.


Never underestimante the power of stupid people in large groups.

It works!
I only forgott this:

PFNGLMULTITEXCOORD2FARBPROC glMultiTexCoord2fARB = 0;
PFNGLACTIVETEXTUREARBPROC glActiveTextureARB = 0;
PFNGLCLIENTACTIVETEXTUREARBPROC glClientActiveTextureARB = 0;

bool multitex_supported(void)
{
char *ext;

ext = (char *) glGetString(GL_EXTENSIONS);

if (!(strstr(ext, "GL_ARB_multitexture")) == 1)
{
return FALSE;
}

else
{
glMultiTexCoord2fARB = (PFNGLMULTITEXCOORD2FARBPROC) wglGetProcAddress("glMultiTexCoord2fARB");
glActiveTextureARB = (PFNGLACTIVETEXTUREARBPROC) wglGetProcAddress("glActiveTextureARB");
glClientActiveTextureARB = (PFNGLCLIENTACTIVETEXTUREARBPROC) wglGetProcAddress("glClientActiveTextureARB");

if (!glActiveTextureARB || !glMultiTexCoord2fARB ||
!glClientActiveTextureARB)
{
return FALSE;
}
}

return TRUE;
}
