HiI compiled the following code with gcc under FC2 : #include <asm/semaphore.h> main() { struct semaphore sum; } It doesn't compile, saying "storage size of `sem' isn't known". and I looked inside asm/semaphore.h, I saw: #ifndef I386_SEMAPHORE_H #define I386_SEMAPHORE_H #include <linux/linkage.h> #endif Did I missed something? Please guide me how to fix it. Sincerely
You're trying to use a kernel data structure in a user-space program. Don't. The definitions in that header are inside #ifdef __KERNEL__ and so the provided userspace headers remove that part.
