gcc编译一个模块，可以通过python导入：

% cython say.py
% gcc `pkg-config --cflags --libs python` -o say.so say.c -lpython2.7 -lpthread -lm -lutil -ldl -fPIC -shared
% /bin/rm say.py   # make sure we aren't just importing say.py
% ls -l say*
-rwxrwxr-x 1 unutbu unutbu 19693 Apr  8 07:52 say.so
-rw-rw-r-- 1 unutbu unutbu 68614 Apr  8 07:52 say.c

% python
Python 2.7.6 (default, Mar 22 2014, 22:59:56) 
[GCC 4.8.2] on linux2
