Gcc编译器报错：gcc -m32报错
:/work/printf_myself$ gcc -m32 -o push_test push_test.c
In file included from /usr/include/stdio.h:27:0,
from push_test.c:12:
/usr/include/features.h:367:25: fatal error: sys/cdefs.h: No such file or direct ory
compilation terminated.
原因：ubantu是64位，执行32位命令报错
解决办法：在保证Ubantu有网的情况下，执行以下命令：
sudo apt-get update
sudo apt-get purge libc6-dev
sudo apt-get install libc6-dev
sudo apt-get install libc6-dev-i386
即可解决。
