I've been working on getting OpenGL to load on windows without a library, and encountered something curious;

Context creation fails when I try to use the function pointer retrieved through GetProcAddress, but works just fine with the statically linked version provided through core.sys.windows.wingdi.d.

This may be a stupid question, but why is this?

Thanks.

Odd.

Just to confirm your wglGetProcAddress, is extern(Windows/System)?
And it is non-null after being loaded?

Yes.
