Zero Opengl 3.2 pixelformat matches found?

Question

Today I finally found out what has been stalling my development process: Even though no errorcode is set, the function wglChoosePixelFormatARB returns 0 pixelformats. I am trying to set up an OpenGL context in my C++ application and I have managed to retrieve the function pointers for the extensions.

glGetIntegerv(GL_MAJOR_VERSION, &maj)

returns 4 so, naturally, I assumed it would be possible to create an OpenGL 3.2 context. However, after finding out there were no matches, I started to comment out some of my requirements to go in the attribList parameter. There were no matches whatsoever. Only when I, just to be certain, commented out

WGL_CONTEXT_MAJOR_VERSION_ARB, 3, WGL_CONTEXT_MINOR_VERSION_ARB, 2,

I finally got matches. Out of the 8 matching pixel formats that the other requirements meet, not ONE of them seems to support version 3 of OGL.

Has anyone ever run into this? I have tried updating/reinstalling my video drivers, but nothing has changed. I am running this on Windows 7, MS Visual Studio 2008, and my graphics card is one from the AMD Radeon HD 7700 Series.

Answer 1

The WGL_CONTEXT_MAJOR_VERSION_ARB, WGL_CONTEXT_MINOR_VERSION_ARB and related attributes are not attributes of the Windows Pixelformat. You must not use them with wglChoosePixelFormatARB().

Those options belong into the attribute list of wglCreateContextAttribsARB as defined by the WGL_ARB_create_context extension.
