Bug ID: 38158
           Summary: Opengl 3.2 need additional declarations to be used
           Product: Wine
           Version: 1.7.37
          Hardware: x86-64
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: winemac.drv
          Assignee: [e-mail]
          Reporter: [e-mail]

Wine detect and use only opengl 2.1

As stated in this documentation page
https://developer.apple.com/library/mac/documentation/GraphicsImaging/Concep...

additional declarations need to be added for Opengl 3.2 core profile to be
enabled.

Please add them.

How did you come to that conclusion?  Do you have a test program?

The reason I ask is that you're wrong.  Wine supports OpenGL 3.2 core profiles
since 1.7.34.  Of course, it's always possible that there's a bug, but you'd
have to identify something specific that's failing to work.

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?

I have the same problem. I got an error when I'm trying to run a game with Wine
(see attachment opengl_error_mac.png). I have a Macbook Air, with Intel HD
Graphics 6000, which supports opengl 3.1 and 3.2 features.

Can you please help me?

I'm afraid there's no help to be had.  With OpenGL 3.1 and later, the version
number is not enough information.  There are different "flavors" of OpenGL. 
Just because your card "supports opengl 3.1 and 3.2 features" doesn't mean that
a game that wants "OpenGL 3.1+" can be satisfied.  The game presumably needs
the "compatibility" flavor of OpenGL 3.1.  MacOS doesn't provide that flavor,
it only provides the "core" flavor.  A game would have to specifically look for
the core flavor in order to get it.  Your game is not prepared to work with the
core flavor of OpenGL 3.1+.  So, it can't work on MacOS and there's nothing
that Wine can do about that.

Sad. I have to use VMWare, because it is the only VM technology where I can
play that game. Hope Apple will give more information about their OpenGL
implementation to other vendors in the future.

Is this problem invalid then?
