64位系统编译32位文件 -m32

gcc编译时加上-m32参数

 gcc -m32 src.c -o outputfile

但是出现了如下错误：
In file included from test.c:1:0:
/usr/include/stdio.h:27:10: fatal error: bits/libc-header-start.h: No such file or directory
#include <bits/libc-header-start.h>
compilation terminated.

其实主要是gcc安装环境没有安装完善

可以尝试输入sudoapt-get install gcc-multilib即可

尚未解决的错误：

-bash: ./test: cannot execute binary file: Exec format error
