Parsing obj. files through opengl

Question

I have an obj. file almost completed. im stuck on the final part with a single error.

   //load the filename textures (only BMP, R5G6B5 format)
    unsigned int objloader::loadTexture(const char* filename){


unsigned int num;
glGenTextures(1,&num);
SDL_Surface* img=SDL_LoadBMP(filename);
glBindTexture(GL_TEXTURE_2D,num);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,img->w,img->h,0,GL_RGB,GL_UNSIGNED_SHORT_5_6_5,img->pixels);
glTexEnvi(GL_TEXTURE_2D,GL_TEXTURE_ENV_MODE,GL_MODULATE);   
SDL_FreeSurface(img);
texture.push_back(num);
return num;}




objloader::objloader() {
//at default we set all booleans to false, so we don't use anything
ismaterial=false;
isnormals=false;
istexture=false; }

the error message i have been getting is:

Error 33 error C2065: 'GL_UNSIGNED_SHORT_5_6_5' : undeclared identifier

if anything else is needed please let me know.

Do you use any extension loading library? Those macros are only defined in higher versions of opengl and thus not in the standard "GL/gl.h" include. — Nobody moving away from SE, Jan 13 '13 at 15:53
Yeah, i have put on glu32.lib, glew32.lib and gltools32.lib. ive also referenced them at the top of the page just to double check — Richard Cripps, Jan 13 '13 at 15:55
The lib files are of no use when it comes to parsing (you need to include the header). As you mention `glew32.lib` did you `#include ` in the file you presented? — Nobody moving away from SE, Jan 13 '13 at 15:57
that was the one i was missing! its cleared up the error, and has brought 4 similar ones involving SDL. il assume it will be the same thing. thank you for the help! — Richard Cripps, Jan 13 '13 at 16:08

Try including <gl/glext.h>
