2 is difficult. To correctly test if _POSIX_VDISABLE is supported, a program must be compiled and run which test if _POSIX_VDISABLE is != -1. But that is not possible for cross compilation, because the program can not be run. Suggestion what should be done here?
The patch did: +#ifdef __ANDROID__ +-- the android ndk does not define this symbol +#define _POSIX_VDISABLE _PC_VDISABLE +#endif so can't you test whether compiling int i = _POSIX_VDISABLE; succeeds? I assume that that will fail on Android with an undefined variable error. Or we could just do #if !defined(_POSIX_VDISABLE) && defined(_PC_VDISABLE) #define _POSIX_VDISABLE _PC_VDISABLE #endif Are you sure the patch is right, though? On Linux I have _POSIX_VDISABLE == 0 and _PC_VDISABLE == 8. Thanks Ian
