Hi Jinzhao,

Did you specify the include path ( as /usr/src/linux-headers-3.11.
0-20-generic/arch/arm/ )
with -I option while compiling your code.

For which architecture you are compiling ?

And I can find "system.h" in the path of "
/usr/src/linux-headers-3.11.0-20-generic/arch/arm/include/asm ".

What is the kernel version that your are using?

If the kernel version > 3.3
#inclued asm/switch_to.h [0]
else
#include <asm/system.h> [1]

Dears:
My system is ubuntu 12.04. In my code, I include the file <asm/system.h>,
but when compiling the code, show the error as "can't find the file or
directory asm/system.h". Why??

Thanks!
