when I include atomic.h, GCC says No such file, why?

Question

I want to use atomic API, and I include . I don't know how to use it! Thank you!

Answer 1

If you know where the file is on your HD, then you say gcc mySource.c -I/path/to/atomic

note that this assumes you include "atomic" directly. and not "some/path/atmomic.h"

Answer 2

I have it in /usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/atomic.h.

I also add -I/usr/src/linux-headers-2.6.28-11/arch/x86/include/ and -I/usr/src/linux-headers-2.6.28-11/include.

some other errors is produced because of -DCONFIG_X86_32 and -D_KERNEL_ macro undefined.

then I define the two macros,

some errors occurred:

/usr/src/linux-headers-2.6.28-11/include/linux/cpumask.h:600:37: error: "and" may not appear in macro parameter list
