如何在 X86_64 CentOS 系统上安装 32 位 gcc 编译器

Question

I have tried the following command:

yum install libgcc.i686  --setopt=protected_multilib=false

But I got some error message from the output:

Transaction Check Error:
  package libgcc-4.8.2-8.el6.x86_64 (which is newer than libgcc-4.4.7-18.el6_9.2.i686) is already installed

So how to fix this issue? I think it's acceptable to keep both two arch version compilers in the system.

Answer 1

You may need to instal i686 components of GCC:

yum install libgcc.i686 glibc-devel.i686

For C++ you will also need

yum install libstdc++-devel.i686

Answer 2

错误消息告诉您库的 x86 和 x86_64 版本必须同步，因此您需要安装/更新两者：

yum install libgcc libgcc.i686
