redhat 7 有 gcc 4.8.5。
我希望它升级到 4.9。为此,我使用了以下命令
sudo yum install devtoolset-3-gcc.x86_64
我得到了以下回复

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我已经确认 mpfr 已安装
[ec2-user@ip-172-31-31-165 ~]$ sudo yum install mpfr-devel
Loaded plugins: amazon-id, rhui-lb, search-disabled-repos
Package mpfr-devel-3.1.1-4.el7.x86_64 already installed and latest version
Nothing to do

我还验证了 gmp 已安装
[ec2-user@ip-172-31-31-165 ~]$ sudo yum install gmp
Loaded plugins: amazon-id, rhui-lb, search-disabled-repos

但是它们都已经存在于我的系统中。我这里遗漏了什么吗?如何在 RHEL 7 中安装 gcc 版本 4.9?
答案1
不是 2000 年的“redhat 7”,而是 RHEL 7:Redhat Enterprise Linux 7
注意:devtoolset-3 不是 gcc/g++ 的更新,而只是 EL7 可用的额外编译器之一。也就是说,您可以同时安装任意数量的 gcc 版本。请确保您已安装系统编译器:#yum install gcc-c++
需要:libmpfr.so.1()(64 位)
需要:libgmp.so.3()(64 位)
“devtoolset-3” 已旧(RHEL 6):1)请安装这些软件包(专为 EL7 构建,“2015 年 1 月”)...... compat-libgmp-4.3.1-1.sl7.x86_64.rpm, compat-libmpfr-2.4.1-1.sl7.x86_64.rpm
链接,兼容 libgmphttps://drive.google.com/file/d/0B7S255p3kFXNZFJDdWtkV3RyZTA/view?usp=sharing...和 compat-libmpfrhttps://drive.google.com/file/d/0B7S255p3kFXNV0FoOVlPemRBS0k/view?usp=sharing
# cd Downloads/ && yum install compat-libgmp-4.3.1-1.sl7.x86_64.rpm compat-libmpfr-2.4.1-1.sl7.x86_64.rpm
2) 不需要完整的 devtoolset-3。这将安装 gcc-4.9 / g++-4.9 :
# yum install devtoolset-3-gcc-c++
... 总共约 4 个软件包。... 'gfortran' :# yum install devtoolset-3-gcc-gfortran
启用 gcc-4.9、g++-4.9:$ scl enable devtoolset-3 bash
...和 $gcc -v
将显示“gcc 版本 4.9”(该设置在退出终端之前有效。)
