There are some documents teaching me on how to build rpm by myself in centos with rpm-build or mock. I am fine to build them for el6 rpm package.

My question is, can I build a rpm package for centos 7 (el7) on a centos 6 server?

The reason is, my company's build server (a bamboo server) is a centos 6 server currently.

Yes and no:

  • Yes, you can do that with Mock. You just run mock -r epel-7-x86_64 yourpackage.src.rpm and it will build package for RHEL/CentOS 7 no matter what is your current host.

  • No, you cannot do that with rpmbuild as that builds packages for your current platform.

  • the second point is not really true: if you set up manually a chroot env with all necessary files from el7, then you could build el7 package for el7 system. However this is exactly what mock does. – Serge May 30 '16 at 16:53
  • Thanks all. I got the point. Mock is the right tool to do the job smoothly with current environment. – Bill May 31 '16 at 0:15
