Hi! Are you wondering how to fix this compilation error or to get the arch package to install?

I do not own the Arch package (maybe someone who does watches this repo and can weigh in) and don't have much experience in debugging install failures on Arch. For the former, I think the answer in that case is to either build on nightly or to build without the unstable feature.

Unfortunately I don't know rust/environment.
Just wanted to install and try it.

Oh hi, I'm the maintainer of frawk's package in the AUR. @ato2 In the future, you may want to first report issues you have with AUR packages as comments in the AUR itself (here's frawk's page: https://aur.archlinux.org/packages/frawk) so as to not waste upstream developers' time 😉

The easiest way to build frawk from the AUR, btw, is to have rustup installed. The PKGBUILD exports a RUSTUP_TOOLCHAIN=nightly environment variable to tell rustup to use a nightly toolchain to build frawk.

I'll see if I can add some kind of message to inform users of this to prevent any further confusion. Cheers!

EDIT: I see there are currently some issues linking against Arch's LLVM libs, I'll have a look at this soon-ish.
