I'm trying to get Flycheck to correctly see where OpenGL is on my Mac, but it can't seem to find it. I've tried adding the following lines to my .clang_complete file, but nothing seems to work. I keep getting the error OpenGL/gl.h could not be found:
-framework OpenGL
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenGL.framework/Headers
This doesn't happen during compilation, it's just messing up static analysis and compilation by Irony. The directory I listed has gl.h and glu.h in it directly, which is probably why it didn't help to add, but I can't figure out how to get Irony to see the files correctly.
Edit: Using Flycheck for syntax checking, not Irony
Edit: macOS X Framework directory:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/
OpenGL.framework/
Headers/
Modules/
OpenGL.tbd/
Versions/
Well, since no one seems to have an answer on this, I'll post my workaround. By symlinking /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenGL.framework/Headers to /usr/local/include/OpenGL, you can give the checker the file path it wants, fixing the issue. Not the best solution, but a decent workaround nonetheless.
