Hi
I compiled the following code with gcc under Redhat
7.2 :
#include <asm/semaphore.h>
main()
{
struct semaphore sum;
}
It doesn't compile, saying "storage size of `sem'
isn't known".
Please guide me how to fix it.
Sincerely
--Hossein Mobahi

I think you a trying to include a file from the linux source
which will not work for use-space apps. Try using
#include <semaphore.h> instead

Hi Hossein,
If you look inside <asm/semaphore.h> you will see that
the definition of struct semaphore is within a
conditional #ifdef __KERNEL__
Hence __KERNEL__ needs to be defined for this code to
compile.
Try compiling like this
$> gcc -D__KERNEL__ file.c

yes, sounds right, since struct semaphore in asm/semaphore will be
defined only if __KERNEL__ is defined.
