unistd.h in macos has this snippet: #if __DARWIN_C_LEVEL >= __DARWIN_C_FULL #define _SC_NPROCESSORS_CONF 57 #define _SC_NPROCESSORS_ONLN 58 #endif /* __DARWIN_C_LEVEL >= __DARWIN_C_FULL */ __DARWIN_C_FULL is 900000L. If _POSIX_C_SOURCE gets defined without __DARWIN_C_SOURCE being defined, __DARWIN_C_LEVEL will be assigned to __DARWIN_C_ANSI, which is 010000L. Thus this definition will remove _SC_NPROCESSORS_CONF. If we don't define _POSIX_C_SOURCE, __DARWIN_C_LEVEL will be equal to __DARWIN_C_FULL, and _SC_NPROCESSORS_CONF will be available. This commit also includes homebrew and macports prefix definitions for mfd_aes_brute. Signed-off-by: İlteriş Yağıztegin Eroğlu <ilteris@asenkron.com.tr> |
