【问题描述】：

我试图在我的从节点中安装 devtoolset-8，但没有运行 centos7 的活动互联网连接。我正在使用所有需要的 .rpm 包作为依赖项。

在安装过程中通过 rpm -ivh * 我得到

error: Failed dependencies:

locate libc.so的输出如下

lib和lib64 libc.so的详细信息如下

[root@node3 install]# ll /usr/lib64/libc.so*

我需要更新 gcc ，唯一的方法是通过 devtoolset 找到它。请提出任何不需要主动互联网连接的可能解决方案。谢谢

您确定需要安装devtoolset-8-systemtap-testsuite吗？这个包只在测试 Systemtap 时需要（甚至使用 Systemtap）。

除此之外，这些符号链接非常不寻常，表明系统出现问题：

lrwxrwxrwx 1 root root 18 Dec 16 16:45 /usr/lib/libc.so -> /usr/lib64/libc.so
lrwxrwxrwx 1 root root 23 Dec 16 17:35 /usr/lib/libc.so.6 -> /usr/lib64/libc-2.17.so

/usr/lib/libc.so 应该是一个链接描述文件，用于链接 32 位版本的 glibc。它由glibc-devel.i686 包安装。
