The reason for this is that you don't have a valid OpenGL context.
But apart from that is there a reason why you're trying to create the texture yourself? Instead of using, say, OSG for that? /ulrich On 16/4/09 6:58 AM, su hu wrote:
After glGenTextures, I use glGetError to get the error.

Zero is returned and no texture is created. Source codes are as follow: ... else if(LoadTexture) { GLuint TexID = 0; glGenTextures(1, &TexID ); .... }
