Description Jeffrey Kuhn 2015-06-30 18:06:28 CEST
Created attachment 701 [details] Patch file for /jocl/make/stub_includes/GL3/gl3.h OSX Version 10.10.3 (Yosemite) I tried a fresh build of JOCL on OSX and found a compiler error. The OSX Framework implementation of OpenGL changed the typedef of GLhanldeARB from 'unsigned int' to 'void *' in /System/Library/Frameworks/OpenGL.framework/Headers/gltypes.h The version in /jocl/make/stub_includes/GL3/gl3.h tries to redefine GLhandleARB to unsigned int. I suggest the following change to gl3.h (patch file attached) #ifndef GL_ARB_shader_objects /* GL types for program/shader text and shader object handles */ typedef char GLcharARB; #if defined(__APPLE__) typedef void *GLhandleARB; #else typedef unsigned int GLhandleARB; #endif #endif

Sounds good, I'll check into why this doesn't work on Yosemite. We do nightly builds for Mac, but I think it's using a slightly older version of the OS, so maybe this recently changed.

Confirmed this bug on Mac OS X 10.10.4 with the latest JOCL code compiled under Java 1.8.0_45. It looks like others have run into this problem as well (e.g. GLEW, described at http://sourceforge.net/p/glew/bugs/206/). Checking to see if Jeff's proposed solution will work on older versions of OS X.
Comment 3 Wade Walker 2015-07-05 16:30:43 CEST
OK, it looks like Khronos fixed it just the way Jeff suggested: https://www.khronos.org/bugzilla/show_bug.cgi?id=762 After Atlassian reported it to them: https://bitbucket.org/alfonse/glloadgen/issue/33/mac-compilation-error So I'll add the same text that you see in https://www.opengl.org/registry/api/GL/glext.h: #ifdef __APPLE__ typedef void *GLhandleARB; #else typedef unsigned int GLhandleARB; #endif
