Hmmm ... we had to fiddle with it to make it work some months ago ... I forget exactly what we did Here's some thoughts - might help. 1. I put my OpenAL stuff here: \usr\local\include\AL 2. Make sure there's no other openal stuff left around in other directories 3. Check that the appropriate lines in alc.h look exactly like this - there was a problem with underscores: #ifdef WIN32 #ifdef _OPENAL32LIB #define ALCAPI __declspec(dllexport) #else #define ALCAPI __declspec(dllimport) #endif #ifdef WIN32 typedef struct ALCdevice_struct ALCdevice; typedef struct ALCcontext_struct ALCcontext; #endif I think there was a problem elsewhere, but I can't identify it right now. If the lines are correct, then the other problem has likely been corrected as well.
