A lot of 3rd party libraries define their own known precision data types similar to what the C99 standardized stdint.h (cstdint for C++) does. Often the typedefs aren't exactly identical and so compile errors arise when a compilation unit needs to include headers for two such conflicting libraries. A recent example I came across when using SDL and Assimp together (it doesn't matter which order I include the files, both orderings cause compile errors):
#include <include/assimp.hpp>
#include <SDL/SDL.h>
int main(int argc, char *argv[]) {
return 0;
}
c:\external\include\include\compiler\pstdint.h(380) : error C2371: 'uint32_t' : redefinition; different basic types
c:\external\include\sdl\sdl_config_win32.h(38) : see declaration of 'uint32_t'
c:\external\include\include\compiler\pstdint.h(410) : error C2371: 'int32_t' : redefinition; different basic types
c:\external\include\sdl\sdl_config_win32.h(37) : see declaration of 'int32_t'
