Include Khronos derived glcorearb.h before cl_gl.h, avoiding typedef mismatch w/ APPLE's GL
LLVM's clang reports a typedef mismatch of GLintptr and GLsizeiptr between the Khronos derived glcorearb.h (from JOGL) and APPLE's gltypes.h when producing 32bit builds. +++ In file included from /usr/local/projects/jogamp/jocl/build-macosx-java6/gensrc/native/jocl/CLAbstractImpl_JNI.c:15: /usr/local/projects/jogamp/jogl/make/stub_includes/opengl/GL/glcorearb.h:604:19: error: typedef redefinition with different types ('ptrdiff_t' (aka 'int') vs 'intptr_t' (aka 'long')) typedef ptrdiff_t GLintptr; ^ /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks/OpenGL.framework/Headers/gltypes.h:51:18: note: previous definition is here typedef intptr_t GLintptr; +++ I.e. Khronos uses ptrdiff_t (aka 'int' on 32bit), where APPLE uses intptr_t (aka 'long' on 32bit). On OSX 32bit both ('int' and 'long') have the same sizeof value, i.e. 4 bytes, see below, hence the ABI is compatible! However, clang produces a typedef mismatch. Fix includes the Khronos derived (JOGL) glcorearb.h before cl_gl.h, hence favors the former 'canonical' definition. +++ OSX 10.10 32bit: sizeof int: 4 sizeof long: 4 sizeof long long: 8 sizeof intptr_t: 4 sizeof uintptr_t: 4 sizeof ptrdiff_t: 4 sizeof size_t: 4 sizeof float: 4 sizeof double: 8 sizeof long double: 16 OSX 10.10 64bit: sizeof int: 4 sizeof long: 8 sizeof long long: 8 sizeof intptr_t: 8 sizeof uintptr_t: 8 sizeof ptrdiff_t: 8 sizeof size_t: 8 sizeof float: 4 sizeof double: 8 sizeof long double: 16
