I have been able to compile it for GL3 (both in 3.0 and 3.1 branches). I did the following modifications: 1) In GL I add two includes, three defines for missing symbols and an ifdef __APPLE__ #if defined(OSG_GL3_AVAILABLE) #ifdef __APPLE__ #include <OpenGL/OpenGL.h> #include <OpenGL/gl3.h> #define GLint64EXT GLint64 #define GLuint64EXT GLuint64 #define GL_BGRA_EXT GL_BGRA #else #include <GL3/gl3.h> #define GL3_PROTOTYPES 1 #endif 2) When compiling my original cmake line lacks extra defines (as seem in osgsimplegl3.cpp). The right line is: /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 \ -D OSG_GLES1_AVAILABLE::BOOL=0 -D OSG_GLES2_AVAILABLE::BOOL=0 \ -D OSG_GL_DISPLAYLISTS_AVAILABLE::BOOL=0 -D OSG_GL_FIXED_FUNCTION_AVAILABLE::BOOL=0 \ -D OSG_GL_MATRICES_AVAILABLE::BOOL=0 -D OSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE::BOOL=0 \ -D OSG_GL_VERTEX_FUNCS_AVAILABLE::BOOL=0 . 3) Setting the pixel format as Stephan suggests. In bool GraphicsWindowCocoa::realizeImplementation(): attr[i++] = NSOpenGLPFAOpenGLProfile; attr[i++] = NSOpenGLProfileVersion3_2Core; In bool PixelBufferCocoa::realizeImplementation() attr[i++] = NSOpenGLPFAOpenGLProfile; attr[i++] = NSOpenGLProfileVersion3_2Core; 4) The osg ffmpeg pluging meeds /usr/lib/libbz2.dylib (this is not related to GL3 and probably is due to how I compiled my copy of ffmpeg) By the way, executing osgsimplegl3 I got lots of errors: Warning: detected OpenGL error 'invalid enumerant' at Before Renderer::compile Warning: Material::apply(State&) - not supported. Warning: TexGen::apply(State&) - not supported. Warning: Material::apply(State&) - not supported. Warning: TexGen::apply(State&) - not supported.
