Re: [gl4java-usergroup] Mac Port: Fetching Function Pointer Dynamically (FindSymbol, ...)

[Sven G. <sgo...@ja...>]

... still no success:

GetSharedLibrary returns 0 -> OK !
FindSymbol returns -2802 -> cfragNoSymbolErr, symbol not found
	tried with GetSharedLibrary:
		OpenGLLibrary
		OpenGLEngine
		OpenGLRenderer
		OpenGLRendererATI

here is the source:

#ifdef macintosh

        #include <Errors.h>

        #define fragNoErr 0
#endif
