I have a FBO used for deferred rendering. It works just as expected when testing on various Nvidia and ATI cards, but there is a GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT when testing on an Intel with the built-in HD 4000 graphics card.

This error message is expected if there is no image attached, but in this case there are several. I don't have access to the PC (64-bit Windows 7) in this case, so I have problem to debug the problem. Any suggestions?

Could it be that some of the texture objects are not supported? I am using GL_DEPTH_COMPONENT24, GL_RGBA, GL_RGBA32F and GL_RGBA16F. It may be that a call to glTexImage2D() failed, as I don't test for gl errors until later (after test for FBO completeness).

For the moment, I don't know the version number of the graphics driver, except that it is "recent".

That particular error can also point to a zero-size or otherwise unusable texture, so yeah, checking for glTexImage2D success would likely uncover that.

I also remember having trouble on Intel GPUs with color attachments that have different formats, but I use OpenGL 2.0 and the old ext_framebuffer_object extension, which has stricter format requirements in the spec.
