我这边没有 centos
我这边用的 archlinux，我这边也没有 bits/c++config.h 这个文件，但是编译不报错
我想重新安装一下 gcc 试试
创建一个虚拟机快照，虽然重新安装 gcc 应该不会出问题，不过还是创建一个保险
yum remove gcc
yum install gcc
我试过了，在我这边把 gcc 删除了，没有任何问题，知道我为什么敢试吗？因为我创建了快照，^_^
不知道 centos 怎么样，应该也没问题吧

前天发现的吧
centos版本是7.9
# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
你帮我安装的{:10_245:}，
我想干脆换个linux试试了

先试试能不能不换系统解决这个问题
yum install libgcc.x86_64 libgcc.i686
换个 archlinux 玩玩？^_^
