In ffi64.c, intel 14.0.0 has an issue with:
{{{
#if defined(__INTEL_COMPILER)
#define UINT128 __m128
#else
...
}}}
At leat on Linux CentOS 6.5, an include directive is required for __m128:
{{{
#if defined(__INTEL_COMPILER)
#include <xmmintrin.h>
#define UINT128 __m128
#else
...
}}}
otherwise, compilation of _ctypes fails.
Regards.

See also the issue #4130. libffi is not part of Python, it's an external project. Python embeds a copy of libffi to limit dependencies... and because we have custom patches on libffi :-/ |
