rare texture mapping problem

Hi,
i have mi method for loading a bmp,
and this is the code:
I'd say its not an OpenGL problem but rather a problem of reading pImageBuffer1.
Try to read the pointers you pass to gluBuild2DMipmaps yourself to see whether this works or not.
The problem here could be that you are using different versions of system DLLs like the CRT DLLs (assuming you're using windows).

Hi, what are the "CRT DLLs"
so, should if thats the problem, should i copy the dlls from my other computer, to this new computer? i think the problem is with the glu/glut library...

CRT DLLs are the common runtine libraries that windows programs use. They might be the problem but thats not for sure.
Did you try to access the fields you pass to gluBuildMipmap by yourself (especially those at the bounds of the array, i.e. the last ones)? Does it crash then? If so, glut itself is not the problem.

yes i did it, and it doesnt crash, and yes, i'm on windows xp.
If i comment the
gluBuild2DMipmaps(GL_TEXTURE_2D, 3, pImageBuffer1->w, pImageBuffer1->h, GL_RGBA, GL_UNSIGNED_BYTE, pImageBuffer1->dat);
the program doesnt crash, but obviously it doesnt map the texture to the primitve....
so.... what can i do? :s
Try this
gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, pImageBuffer1->w, pImageBuffer1->h, GL_RGBA, GL_UNSIGNED_BYTE, pImageBuffer1->dat);
and make sure your data is arranged as RGBA and not BGRA
gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, pImageBuffer1->w, pImageBuffer1->h, GL_RGBA, GL_UNSIGNED_BYTE, pImageBuffer1->dat);
and make sure your data is arranged as RGBA and not BGRA
