semaphore.h is just a plain old header. I don't have a hardware.h that I can tell, but I don't do a lot of (i.e. any) fancy hardware programming.
Porting code from one OS to another is a minefield.
Which OS was the code for to begin with?
The semaphore.h in /usr/include involves the same library functions as the one in the kernel tree (pretty sure anyway), which that's probably what asm/ is referencing. There is a hardware.h in the tree too, but there's not just one "asm" subdirectory, you need to pick an architecture.
You can find the kernel includes via /lib/modules/source/include.
Okay well for semaphore i just did
#include "linux/semaphore.h"
and that didnt give me a compiler error so i guess tahts works but where would tehre be a generic hardware.h
I found one in 2.6.28.7, not much too it and definitely ain't generic:Quote:
