Question

Any ideas why the following code causes glGetError() to return 1280, or invalid enumerant when the OpenGL 3.3 Core Profile is loaded?

GLuint texture = 0;
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);

glTexImage2D(GL_TEXTURE_2D, 0,
    GL_RGB,
    textureImage.Width(), textureImage.Height(), 0,
    GL_RGB, GL_UNSIGNED_BYTE,
    textureImage.Bytes()
);

It works fine if I don’t load the core profile and actually it doesn’t seem to fail other than the error code if I use AMD’s gDebugger to view the texture’s contents. The texture is a 256 x 256 png that I’m using stb_image.c to load into ram.

glewInit() is actually causing the Invalid Enum with the core profile selected.
