Hello everyone.

I’ve been struggling with Genie on my laptop running Fedora for a while now. It worked once upon a time, but now it seems to fail to precompile along with Nettle and Nettle\_jll. Is anybody else having this problem? I’ve uninstalled and reinstalled both Julia and the packages in question. I’ve searched for a solution on google, but I can’t see any evidence of anyone with the same problem. I’m a bit of a beginner so I’m sorry if the answer is something obvious.

I’ve posted the output below.

Welcome! How did you install Julia? `libgmpxx.so.4` should be part of the Julia distribution. This is for example the case for the [official binaries](https://julialang.org/downloads/).

My educated guess is that you installed Julia from the repositories of a Linux distribution? If so, you should complain with the maintainer of the package, or switch to using the official binaries (which is a better option anyways).

Actually, since you mentioned this is Fedora, @nalimilan may be the one to ping.

Managed to fix the problem with the help of the helpful folks on the Humans of Julia Discord server.

Installing gmp-devel fixed the problem.
