glibc-2.17 is rather old. The requirement for 2.27 would be because that'd have
been the version of glibc on the system where the rpm was built. I'm quite sure
that 2.17 would be okay, but, without a system old enough to verify that, it's
hard to be sure.

The rpms were built on a recent Fedora system.

It has nothing to do with the rpm format. Actually, the Red Hat reference comes
from a long time ago when Fedora was known as Red Hat Linux. CentOS, which,
ultimately, is a copy of Red Hat Enterprise Linux, would also support the rpms.
the problem is that those releases tend to be so old that any rpm built for a
more recent system might, as you've discovered, have dependency issues.

I suppose that we could maintain an older system for building the rpms, but the
insentive to do so isn't very great. I think the right approach would be to ask
the CentOS people to build the rpms for their distribution so that they'd get
picked up by their package management process.

>Or is there a way to get these RPMs to install on Centos 7?

You could always specify the option to ignore the dependency issues.

I don't have a CentOS system, or even an old enough Fedora system, on which to
experiment.

You could always not use the rpms and build from the source tarball.
