Question

I have an application which I usually run on Nvidia graphics card. I thought I’d try running it on the Sandy Bridge Intel HD Graphics 3000.

However, when I’m running on the intel hardware I get an “framebuffer not complete” from the following initialization code:

glGenFramebuffers(1, &fbo_);        
glBindFramebuffer(GL_FRAMEBUFFER_EXT, fbo_);
glReadBuffer(GL_COLOR_ATTACHMENT0_EXT);
glDisable(GL_MULTISAMPLE_ARB); 
// Error: "the object bound to FRAMEBUFFER_BINDING_EXT is not "framebuffer complete"

Any ideas why?

Answer 1

You kinda need at least one color attachment (before OpenGL 4.3 at least).
