C includes must be adapted to work on all compilers or at least the compiler you are using.
You'll need to use fd2pragma or a similar tool.
Perhaps you'll find aweb includes useful (AFAIK they are already adapted for GCC and OS4/OS3/MOS):
http://aweb.sunsite.dk/if your includes are already adapted that errors may have appeared because you haven't included the function prototypes.
You may have to add a:
#include
or even a
#include
you should never have to add:
#include
and you should never have to add
#include
as proto/cybergraphx.h should already choose that files. if you use inline or clib headers instead of proto ones your code won't be directly portable to other compilers (gcc uses "inline/" directory but other compilers don't.
good luck!
