尝试从安装 C++开发工具集-3我的 CentOS6 系统遇到了依赖问题：

bash-4.2# yum install devtoolset-3-gcc-c++
Loaded plugins: fastestmirror

You could try using --skip-broken to work around the problem

对我来说，这看起来像是一个错误：SCL 应该包含该库的更新包...但也许我错过了一些东西？

答案1

错误输出中的两个库由 mpfr 和 gmp 提供，它们位于基础存储库中。

$ repoquery --whatprovides 'libmpfr.so.1()(64bit)'
mpfr-0:2.4.1-6.el6.x86_64
$ repoquery --whatprovides 'libgmp.so.3()(64bit)'
gmp-0:4.3.1-7.el6_2.2.x86_64

如果 yum 无法看到它们，则可能是在 yum 配置中排除了它们。
