If this package is out of date for a day or two while I catch up, you can use change the nightly release date as specified in the releases page: https://github.com/riscv-collab/riscv-gnu-toolchain/releases

If anyone wants to maintain or has a better PKGBUILD feel free

The package cannot be installed along with gcc:

...
error: failed to commit transaction (conflicting files)
riscv-gnu-toolchain-bin: /usr/share/gcc-12.2.0/python/libstdcxx/__init__.py exists in filesystem (owned by gcc)
...

1. 11.1.0 must be replaced with 12.2.0.
2. Also noticed that _target is unused.

Update: There is already a PR

OK so this package is still just downloading the binaries, and is essentially (or completely) the same as riscv-gnu-toolchain-bin. Would be great if you make this package build from sources, or remove it? But many thank yous for packaging!

Hey @supergarfield I added you as a comaintainer if you'd like, or if you would like to maintain this just let me know

Yeah, same problem as @maleadt. I changed the PKGBUILD as follows and it looks like it fixed the issue:

(Some changes like checksums are not actually necessary, of course)

How do you use the RISCV toolchain as packaged here? GCC seems confused by everything existing in /usr/bin and falls back to the host as which obviously does not work:

$ riscv64-unknown-elf-gcc dummy.c -march=rv32im -mabi=ilp32  -v
[...]
 as -v --traditional-format -march=rv32im -march=rv32im -mabi=ilp32 -o /tmp/cckCT3Al.o /tmp/ccOBmH6G.s
GNU assembler version 2.36.1 (x86_64-pc-linux-gnu) using BFD version (GNU Binutils) 2.36.1
Assembler messages:
Fatal error: invalid -march= option: `rv32im'

Extracting the upstream binaries in their own folder (e.g. /opt/riscv-gnu-toolchain) does result in a working compiler.

Thank you felix, I moved the nightly style build to https://aur.archlinux.org/packages/riscv-gnu-toolchain-bin/

I will modify this PKGBUILD to create from source.

Secondly, thanks for confirming that it's okay to get creative with pkgver()!

I will adjust any other, or future -git packages :)

-git ones are supposed to using git sources and do not need any changes to always point to the latest source (with the help of a pkgver() function). This package could build from source of a tag (pre-released one works too imho, if there is no stable release).

I agree that you should move the current downloading-binary one to -bin :)

Hey Felix, thanks for the feedback as I was considering making a -git version for built versions.

Alternatively, should I move this rendition to -bin and replace this with the build from sources one with the extra flags instead of using -git?

Hi. Since this package is installing from pre-built binary packages, it should use the "-bin" suffix (e.g. riscv-gnu-toolchain-bin).

Also upstream is marking releases as pre-releases, so that a "-nightly" suffix may help too. I am not sure if they are going to make "stable" releases ever, so this is up to you (e.g. riscv-gnu-toolchain-nightly-bin).
