Hi, When I compile lesson 7 in C++ Builder X the program terminates with a divide by zero exception. After debugging, I have determined that the exception occurs during the call to gluBuild2DMipmaps in LoadGLTextures. glBindTexture(GL_TEXTURE_2D, texture[2]); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_NEAREST); gluBuild2DMipmaps(GL_TEXTURE_2D, 3, TextureImage[0]->sizeX, TextureImage[0]->sizeY, GL_RGB, GL_UNSIGNED_BYTE, TextureImage[0]->data); Does anyone have any ideas how to fix this? Thanks, Jason
