The Rust install process doesn't mention it, but sudo apt install build-essential is needed to get it to work. Might be worth a mention in the readme?

Thanks for the excellent app ❤️

I agree that it's a good idea to mention this in order to preempt future issues, but I'm not sure what the best way to do it would be. I don't want to include installation instructions for every conceivable distribution (i.e. apt install build-essential, pacman -S base-devel, eopkg it -c system.devel etc.), but just telling people to install a linker might not be enough.

I think just adding the gcc toolchain to the prerequisites might be the simplest solution, even though I don't know if that's actually the only linker that works. Sadly there doesn't seem to be any official Rust documentation that could be linked to, which explains this dependency and how best to satisfy it.

I guess ideally this wouldn't be an issue for this repo, but rather the Rust install instructions should likely be amended to mention this since it seems to just be a requirement for Rust in general.

I am not very familiar with Rust, but it looks like they already have an open issue for this.
