For example, pycrypto fails: $ pip install pycrypto Collecting pycrypto ....... building 'Crypto.PublicKey._fastmath' extension creating build/temp.cygwin-2.6.0-x86_64-2.7 creating build/temp.cygwin-2.6.0-x86_64-2.7/src gcc -fno-strict-aliasing -ggdb -pipe -Wimplicit-function-declaration -fdebug-prefix-map=/usr/src/ports/python/python-2.7.12-1.x86_64/build=/usr/src/debug/python-2.7.12-1 -fdebug-prefix-map=/usr/src/ports/python/python-2.7.12-1.x86_64/src/Python-2.7.12=/usr/src/debug/python-2.7.12-1 -fwrapv -Wall -Wstrict-prototypes -std=c99 -O3 -fomit-frame-pointer -Isrc/ -I/usr/include/ -I/usr/include/python2.7 -c src/_fastmath.c -o build/temp.cygwin-2.6.0-x86_64-2.7/src/_fastmath.o In file included from /usr/include/python2.7/Python.h:8:0, from src/_fastmath.c:31: /usr/include/python2.7/pyconfig.h:1221:0: warning: "__BSD_VISIBLE" redefined #define __BSD_VISIBLE 1 ^ In file included from /usr/include/sys/config.h:5:0, from /usr/include/_ansi.h:16, from /usr/include/stdio.h:29, from src/_fastmath.c:29: /usr/include/sys/features.h:250:0: note: this is the location of the previous definition #define __BSD_VISIBLE 0 ^ In file included from /usr/include/python2.7/pyport.h:332:0, from /usr/include/python2.7/Python.h:58, from src/_fastmath.c:31: /usr/include/sys/time.h:104:34: error: unknown type name ‘u_int’ bintime_mul(struct bintime *_bt, u_int _x) ^ error: command 'gcc' failed with exit status 1 ---------------------------------------- I can fix these errors by changing __BSD_VISIBLE from 1 to 0 in /usr/include/python2.7/pyconfig.h.
