Looking at the upstream project, it doesn't look too bad.

Rust packaging uses dynamically generated BuildRequires, similar to modern Python packaging. "dnf builddep" does not work for packages that use this feature, unless you take additional steps (I think running "rpmbuild -br" first). However, recommend *in the strongest possible way I can* to use *mock* for building Rust packages. Everything else is a way towards pain. > Running "rpmbuild -bb" shows a bunch of unsatisfied deps, but I can't find all > of them as prepackaged rpms. As I mentioned, please do not build Rust packages on your host OS. Use mock. It supports building packages that use dynamic BuildRequires OOTB. > The git-repository crate that stgit depends on, if I download it with crate > install, it can't be installed as it doesn't have an executable in it. I > think the problem is that it's just a library. You will need to package missing dependencies - like the git-repository crate - separately (as rust-git-repository). Running "cargo install" does not work for library-only crates. And I don't know running "cargo install git-repository" would help you? Package builds do not have internet access. I haven't looked at all of them individually, but at a glance, almost all dependencies of stgit should already be packaged for fedora: https://github.com/stacked-git/stgit/blob/master/Cargo.toml#L19-L47 Only the git-repository crate is not packaged yet, as far as I can see. Other than that, the only problem I see straight away is that we don't have clap v4 in Fedora yet (because clap v4 started to use features of cargo that our tools do not support yet). Looking back at the history of stgit, it seems that all releases of it already use clap v4, so that will be a problem until I have time to fix our tools for https://bugzilla.redhat.com/show_bug.cgi?id=2152697 .
