在 RHEL 7 中將 gcc 升級到 gcc-4.9

redhat 7 有 gcc 4.8.5。

我希望它升級到4.9。為此，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

我已驗證 mpfr 已安裝

[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

我還驗證了 gmp 已安裝

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

但它們都已經存在於我的系統中。我在這裡錯過了什麼嗎？如何在 RHEL 7 中安裝 gcc 4.9 版本？

答案1

不是 2000 年的“redhat 7”，而是 RHEL 7：紅帽企業 Linux 7

注意：devtoolset-3 不是 gcc/g++ 的更新，而只是 EL7 可用的額外編譯器之一。也就是說，您可以同時安裝任意多個 gcc 版本。請確保您已安裝系統編譯器：#yum install gcc-c++

需要：libmpfr.so.1()(64位元)

需要：libgmp.so.3()(64位元)

「devtoolset-3」是舊的（RHEL 6）：1）請安裝這些軟體包（為 EL7 構建，「2015 年 1 月」）... compat-libgmp-4.3.1-1.sl7.x86_64.rpm, compat-libmpfr-2.4.1-1.sl7.x86_64.rpm

鏈接，compat-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。這將安裝 gcc-4.9 / g++-4.9 : # yum install devtoolset-3-gcc-c++... 總共 ~4 個軟體包。 ...'gfortran'：# yum install devtoolset-3-gcc-gfortran

啟用 gc​​c-4.9、g++-4.9 ： $ scl enable devtoolset-3 bash... 和 $gcc -v會顯示“gcc version 4.9”（該設定在退出終端之前一直有效。）
