我正在尝试在 AIX 服务器上使用 pip for python 3.5 安装 cffi 包，但它失败并出现关于 xlc_r 的错误以及关于找不到 libffi 包的错误。
点安装 cffi

No working compiler found, or bogus compiler options passed to
the compiler from Python's standard "distutils" module. See
the error messages above. Likely, the problem is not related
to CFFI but generic to the setup.py of any Python package that
tries to compile C code. (Hints: on OS/X 10.8, for errors about
-mno-fused-madd see http://stackoverflow.com/questions/22313407/
Otherwise, see https://wiki.python.org/moin/CompLangPython or
the IRC channel #python on irc.freenode.net.)
Trying to continue anyway. If you are trying to install CFFI from
a build done in a different context, you can ignore this warning.

我在哪里找到 libffi：
/opt/freeware/lib > ls -lrt | grep libffi
-rwxr-xr-x 1 root system 25553 Nov 25 2014 libffi.so.6
-rwxr-xr-x 1 root system 92378 Nov 25 2014 libffi.so.5
-rwxr-xr-x 1 root system 250592 Nov 25 2014 libffi.a
我试过这个http://www.rootvg.net/content/view/812/169/。不工作。我在 AIX 7.1 上使用 python3.5
在这里期待有关修复的建议。
