On Fedora 30, I ran into this problem "Failed to build gem native extension". The log error was "gcc: fatal error: cannot read spec file ‘/usr/lib/rpm/redhat/redhat-hardened-cc1’: No such file or directory". The solution was found here.

If you installed all the above, but the extensions would still not compile, you are probably running a Fedora image that misses redhat-rpm-config package. In that case gcc compiler would complain about one of the following:

To solve this, simply run sudo dnf install redhat-rpm-config.
