--- Comment #3 from Ken Thomases <ken at codeweavers.com> ---
You could have been clearer.  I gather that you ran the glewinfo.exe program
from
<https://sourceforge.net/projects/glew/files/glew/1.12.0/glew-1.12.0-win32.zip/download>.

What about that output is different from what you expect?

Is this the problem:

> OpenGL version 2.1 NVIDIA-10.0.19 310.90.10.05b12 is supported

?

>From a +wgl log, it looks like glewinfo.exe/GLEW is just calling
wglCreateContext().  It's not calling wglCreateContextAttribsARB(), let alone
specifying any attributes.

When an app calls wglCreateContext(), the implementation may return a context
of any version that is backward-compatible with OpenGL 1.0.  As per the
WGL_ARB_create_context spec, that can include versions up through 3.0, version
3.1 with GL_ARB_compatibility, or version 3.2 (or later) compatibility profile.

OS X does not provide GL_ARB_compatibility, so 3.1 is not acceptable. 
Likewise, it does not provide compatibility profiles for 3.2 or later.  It only
provides core profiles.  In fact, they are the more restrictive
forward-compatible core profiles.

On OS X, an app can only obtain a 3.2 core profile if it calls
wglCreateContextAttribsARB() and specifies version 3.2, 3.3, 4.0, or 4.1;
WGL_CONTEXT_FLAGS_ARB == WGL_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB; and
WGL_CONTEXT_PROFILE_MASK_ARB == WGL_CONTEXT_CORE_PROFILE_BIT_ARB.  glewinfo.exe
does not do that, so it just gets a 2.1 context.

Was glewinfo.exe the real thing you wanted working?
