背景

在64位机器上编译32位可执行程序，出现以下报错，

[root@CentOS-7-4 /home/syscall]# gcc -g -static -m32 open.c -o open32
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status

解决方案

这其实是因为缺少32位相关编译环境，需要安装glibc-static组件，

yum install -y glibc-static.i686

安装后，编译正常，

[root@CentOS-7-4 /home/syscall]# gcc -g -static -m32 open.c -o open32
[root@CentOS-7-4 /home/syscall]# ls
.  ..  open32  open.c 
[root@CentOS-7-4 /home/syscall]# file open32
