Hi,
I'm trying to compile an application in Mac that requires OpenGL 3.2. The app
starts but fails when compiling the shaders and seems that, by default, OSG
3.0.1 compiles without OpenGL 3 support.
My next step was to recompile OSG with these settings:
/usr/bin/cmake -G Xcode -D OSG_COMPILE_FRAMEWORKS:BOOL=1 -D
OSG_WINDOWING_SYSTEM:STRING=Cocoa -D OSG_BUILD_PLATFORM_IPHONE:BOOL=0 -D
CMAKE_OSX_ARCHITECTURES:STRING=x86_64 -D
OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX:STRING=imageio -D
CMAKE_OSX_SYSROOT:STRING=/Developer/SDKs/MacOSX10.7.sdk -D
OSG_GL3_AVAILABLE::BOOL=1 -D OSG_GL1_AVAILABLE::BOOL=0 -D
OSG_GL2_AVAILABLE::BOOL=0 .
And seems that this time uses GL3 as it fails to compile with the error:
include/osg/GL:109:18: fatal error: 'GL3/gl3.h' file not found [2]
Then I add the missing includes to the path and I got a lot of errors:
/usr/include/GL3/gl3.h:85:9: warning: 'GL3_PROTOTYPES' macro redefined [2]
#define GL3_PROTOTYPES
^
OpenSceneGraph/include/osg/GL:108:17: note: previous definition is here

inline void glLoadMatrix(const float* mat) {

^~~~~~~~~~~~~
glLoadMatrix

OpenSceneGraph/include/osg/GL:130:17: note: 'glLoadMatrix' declared here [3]

'glMultMatrixf'; did you mean 'glMultMatrix'? [3]
inline void glMultMatrix(const float* mat) {
glMultMatrixf(static_cast<const GLfloat*>(mat)); }
^~~~~~~~~~~~~
glMultMatrix
… and more …
The question is now, can OpenGL 3.2 be use in Mac OS X? I'm doing something
wrong?
Thanks a lot,
David
