indirect.c: In function 'setup_dispatch_table': indirect.c:1268: error: 'glBlitFramebufferEXT' undeclared (first use in this function) indirect.c:1268: error: (Each undeclared identifier is reported only once indirect.c:1268: error: for each function it appears in.)

The problem starts at lines #57: 57 #include <OpenGL/OpenGL.h> 58 #include <OpenGL/CGLContext.h> 59 60 // X11 and X11's glx 61 #include <GL/gl.h> 62 #include <GL/glxproto.h> 63 #include <windowstr.h> 64 #include <resource.h> 65 #include <GL/glxint.h> 66 #include <GL/glxtokens.h> 67 #include <scrnintstr.h> 68 #include <glxserver.h> 69 #include <glxscreens.h> 70 #include <glxdrawable.h> 71 #include <glxcontext.h> 72 #include <glxext.h> 73 #include <glxutil.h> 74 #include <glxscreens.h> 75 #include <GL/internal/glcore.h> 76 #include "x-hash.h" 77 #include "x-list.h" /System/Library/Frameworks/OpenGL.framework/Headers/CGLContext.h is included on place of <OpenGL/CGLContext.h>. Followed by . /System/Library/Frameworks/OpenGL.framework/Headers/CGLContext.h .. /System/Library/Frameworks/OpenGL.framework/Headers/gliContext.h .. /System/Library/Frameworks/OpenGL.framework/Headers/gliDispatch.h ... /System/Library/Frameworks/OpenGL.framework/Headers/gl.h .... /System/Library/Frameworks/OpenGL.framework/Headers/glext.h . /usr/X11/include/GL/gl.h . /usr/X11/include/GL/glxproto.h .. /usr/X11/include/GL/glxmd.h So we see that /System/Library/Frameworks/OpenGL.framework/Headers/ glext.h is included from an Apple version of GL/gl.h, /System/Library/ Frameworks/OpenGL.framework/Headers/gl.h. This has on line #64: 64 #ifndef GL_GLEXT_LEGACY 65 #include <OpenGL/glext.h> 66 #endif /usr/X11/include/GL/gl.h, which includes (the proper) <GL/glext.h> (that has glBlitFramebufferEXT) has on line #2140: 2140 /* 2141 * Define this token if you want "old-style" header file behaviour (extensions 2142 * defined in gl.h). Otherwise, extensions will be included from glext.h. 2143 */ 2144 #if defined(GL_GLEXT_LEGACY) 2145 2146 /* All extensions that used to be here are now found in glext.h */ 2147 2148 #else /* GL_GLEXT_LEGACY */ 2149 2150 #include <GL/glext.h> 2151 2152 #endif /* GL_GLEXT_LEGACY */ GL_GLEXT_LEGACY is not defined in any /System/Library/Frameworks/ OpenGL.framework/Headers file, nowhere in the pre-proceessed indirect.c file, so <GL/glext.h> should be included. But all I can see in the pre-proceessed indirect.c file is: # 59 "indirect.c" 2 # 1 "/usr/X11/include/GL/gl.h" 1 # 62 "indirect.c" 2 # 1 "/usr/X11/include/GL/glxproto.h" 1 #define _GLX_glxproto_h_ # 34 "/usr/X11/include/GL/glxproto.h" # 1 "/usr/X11/include/GL/glxmd.h" 1 #define _GLX_glxmd_h_ # 42 "/usr/X11/include/GL/glxmd.h" typedef float FLOAT32; typedef double FLOAT64; # 52 "/usr/X11/include/GL/glxmd.h" #define F32 # 35 "/usr/X11/include/GL/glxproto.h" 2 and no further mentioning of /usr/X11/include/GL/gl.h. All data types are taken from /System/Library/Frameworks/OpenGL.framework/Headers/gl.h. This obviously is going to persist even if I switch to Mesa 7.0.4 and X11R7.4 since xserver and operating system stay the same. So it might be appropriate to #include <GL/glext.h> in case of Tiger in indirect.c after line #61 ... -- Greetings Pete Specifications are for the weak and timid!
