size_t is undefined PUGIXML

I’m trying to use pugixml, and i added the headers, but i get size_t is undefined. What’s the solution?

#include <cstddef> ?

tried,nothing happens

Could you past the whole output (error) here?

Solution: just add to the includes you android ndk folder with \toolchains\arm-linux-androideabi-4.6\prebuilt\windows\lib\gcc\arm-linux-androideabi\4.6\include
