Compilation failure on OS X El Capitan

Created by: msakai

I failed to compile OpenCL-1.0.3.4 on Mac OS X El Capitan (10.11.4) with the following error.

Preprocessing library OpenCL-1.0.3.4...
c2hs: C header contains errors:

/System/Library/Frameworks/OpenGL.framework/Headers/CGLDevice.h:19: (column 28) [ERROR]  >>> Syntax error !
  The symbol `CGLGetShareGroup' does not fit here.

It seems that the __nullable annotation confused c2hs. Here are some code snippet that might be relevant to the problem.

CGLDevice.h:

15  OPENGL_ASSUME_NONNULL_BEGIN
16  
17  typedef struct CGLShareGroupRec *CGLShareGroupObj OPENGL_AVAILABLE(10_6);
18  
19  CGLShareGroupObj OPENGL_NULLABLE CGLGetShareGroup(CGLContextObj ctx) OPENGL_AVAILABLE(10_6);
20

CGLTypes.h:

14  #if __has_feature(assume_nonnull)
15  #define OPENGL_ASSUME_NONNULL_BEGIN _Pragma("clang assume_nonnull begin")
16  #define OPENGL_ASSUME_NONNULL_END _Pragma("clang assume_nonnull end")
17  #else
18  #define OPENGL_ASSUME_NONNULL_BEGIN
19  #define OPENGL_ASSUME_NONNULL_END
20  #endif
21  
22  #if __has_feature(nullability)
23  #define OPENGL_NULLABLE __nullable
24  #define OPENGL_NONNULL __nonnull
25  #else
26  #define OPENGL_NULLABLE
27  #define OPENGL_NONNULL
28  #endif
