Origin of these macros: setup.py:1767: extra_compile_args.append('-DUSING_MALLOC_CLOSURE_DOT_C=1')
setup.py:1804: ext.extra_compile_args.append("-DUSING_APPLE_OS_LIBFFI=1")
pyconfig.h.in: /* Define if the internal form of wchar_t in non-Unicode locales is not Unicode. */ #undef HAVE_NON_UNICODE_WCHAR_T_REPRESENTATION /* Define WORDS_BIGENDIAN to 1 if your processor stores words with the most significant byte first (like Motorola and SPARC, unlike Intel). */ #if defined AC_APPLE_UNIVERSAL_BUILD # if defined __BIG_ENDIAN__ # define WORDS_BIGENDIAN 1 # endif #else # ifndef WORDS_BIGENDIAN # undef WORDS_BIGENDIAN # endif #endif |
Sorry, something went wrong.
_ctypes/malloc_closure.c: #ifdef HAVE_FFI_CLOSURE_ALLOC, #ifdef USING_APPLE_OS_LIBFFI
