Hey, I've been trying to install lispbuilder on OS X 10.8.4. I've installed SDL without any problems in my /Library/ folder. I unpacked lispbuilder there as well, but when I go to cocoahelper and run make I get this error.
make -C glue
g++ -dynamiclib -g -Wall -D_GNU_SOURCE=1 -D_THREAD_SAFE -I/Library/Frameworks/SDL.framework/Headers -c -o lispbuilder-sdl-glue.o lispbuilder-sdl-glue.c
clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated
clang: warning: argument unused during compilation: '-dynamiclib'
In file included from lispbuilder-sdl-glue.c:31:
./lispbuilder-sdl-glue.h:27:10: fatal error: 'SDL.h' file not found
#include <SDL.h>
^
1 error generated.
make[1]: *** [lispbuilder-sdl-glue.o] Error 1
Any suggestions what I can do?
