How can I downgrade to a specific gcc version on Fedora 39?

Question

I need to downgrade from gcc-13 to gcc-12 for multiple projects to compile. I couldn't find a straight forward way of doing so.

dnf list gcc just shows me version 13.

See: Debian Bullseye: Install gcc-11.4.0 and dependencies. Different OS, but same issue. Fedora 39 was most likely built with GCC 13 and it's dependencies — eyoung100, Jan 25 '24 at 17:43
Took me a minute to find this question again but I wrote a question and answer for situations like yours, using this question as the example. See: I'm Using Distribution $X That was shipped With Compiler $Y, but I Need Compiler Version $Z — eyoung100, Jan 25 '24 at 23:11
Does this answer your question? Can I force dnf to install an old version of a package? — killertofus, Jan 25 '24 at 23:45
@cinemassacres that only works if the older package is available in the repositories; the Fedora 39 repositories only provide GCC 13. — Stephen Kitt, Jan 30 '24 at 06:26

You can install using a specific name-version as described in the man page:

dnf install gcc-12.0.0-0.3.fc36

To view all versions of a package in your enabled repositories, use:

dnf --showduplicates list <package>
