Centos7 i686和x86_64区别

Linux64位操作系统,开发了个小程序,无法运行。
卸载掉系统已安装的glibc.X86_64,然后安装glibc.i686(yum install glibc.i686),程序能够正常运行了。
请教大神,这两种glibc有什么区别吗?两种后缀各是什么意思?求指点

能解释一下程序由不能运行到能运行的原因吗?

Technically, i686 is actually a 32-bit instruction set (part of the x86 family line), while x86_64 is a 64-bit instruction set (also referred to as amd64).

From the sound of it, you have a 64-bit machine that has 32-bit libraries for backwards compatibility. That should be totally fine.
