如何将 Fedora Repo 添加到 CentOS 7 安装？

Question

我有一个 CentOS 7 x86_64 安装，我想在上面安装一个名为frama-c. 这个包不在我目前配置的 repos 中：

# yum search frama-c
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: centos.datente.com
 * epel: epel.besthosting.ua
 * epel-testing: epel.besthosting.ua
 * extras: centos.mirror.iphh.net
 * updates: artfiles.org
Warning: No matches found for: frama-c
No matches found

我已经fullfilelist从https://dl.fedoraproject.org/pub/fedora/下载了，当我 grep for frama-c 时，结果看起来很有希望：

$ grep 'development.*x86_64.*frama-c' fullfilelist.txt
./linux/development/26/Everything/x86_64/debug/tree/Packages/f/frama-c-debuginfo-1.14-1.fc26.x86_64.rpm

将 rawhide 存储库添加到我当前的存储库列表中的正确方法是什么，以便我可以安装一个yum install frama-c？

为不同的系统混合包从来都不是一个好主意。它可能有效，但您可能会遇到难以调试的问题。但很可能它不会起作用。

最好的方法是为您的系统重建软件包。您可以要求当前的包维护者为您完成（添加 EPEL7 包，它将显示在您的 EPEL 存储库中）或您自己完成：

• 从Koji下载最新的 SRPM 包：

  wget https://kojipkgs.fedoraproject.org//packages/frama-c/1.14/1.fc27/src/frama-c-1.14-1.fc27.src.rpm
  

• 为您的系统重建它（可能解决缺少的依赖项，如果它们可用）：

  rpmbuild --rebuild frama-c-1.14-1.fc27.src.rpm
  

• 安装软件包：

  yum install ~/rpmbuild/RPMS/.../path/../to/your.rpms
