Hi @xiretza,

In addition to the pdm_build.py patch proposed by @salfter, would you mind adding python-jschon to your depends, and python-packaging and python-pdm-backend to your makedepends?

Without those entries, python-amaranth-git fails to build in a clean chroot.

Regards
Claudia (aka Auerhuhn)

I've forked this repo:

https://aur.archlinux.org/packages/python-amaranth

It grabs the most recent release (currently v0.4.5) and builds it. It adds a git checkout to the prepare() function, and applies the patch I posted below.

FWIW, I maintain a Gentoo ebuild for this package. When upstream switched over to PDM, I found I had to patch pdm_build.py as follows:

 def pdm_build_initialize(context):
-    version = Version(context.config.metadata["version"])
-    if version.is_prerelease:
-        url_version = "latest"
-    else:
-        url_version = f"v{version}"

+    #    url_version = "latest"
+    #else:
+    url_version = f"v0.4.5"
     context.config.metadata["urls"]["Documentation"] += url_version

Note that (1) I'm building from release tarballs instead of Git master and (2) url_version needs to be set to the actual version you're building. Whether this is applicable or not to the Arch PKGBUILD, I'm not certain. I might try my hand at knocking together a release-version PKGBUILD to see if it makes any difference.

Correction: my ebuild pulls from Git, but it uses the commit corresponding to the release. (Specifically, it uses git-r3.eclass and sets EGIT_COMMIT and EGIT_BRANCH as well as EGIT_REPO_URI.) If I remember right, I had trouble building from the release tarballs for some reason.

=sci-electronics/amaranth-0.4.5::salfter builds against =dev-python/pdm-backend-2.2.1::gentoo without error. I've noticed that the version of pdm-backend Arch is installing is 2.3.0. I keyworded pdm-backend to ~amd64 and rebuilt both pdm-backend (2.3.0) and amaranth without error, so it doesn't appear to be a matter of breakage between pdm-backend versions.

On my my system, this fails with

Maybe the Arch upstream of python-pdm is too old? Alternatively, we can consider working around this in the PKGBUILD by patching $srcdir/amaranth/pyproject.toml to remove the version_format = "pdm_build:format_version" and deleting src/amaranth/pdm_build.py. I'll leave this decision up to you as I am not inherently familiar with this project (or python build systems for that matter).

python-amaranth-boards-git is now packaged: https://aur.archlinux.org/packages/python-amaranth-boards-git

xiretza commented on 2022-04-24 07:33 (UTC)

Tests exist to tell you when something is wrong, simply not running them can hardly be considered a "fix" ;) Anyway, the issue is that amaranth targets the latest available yosys, so I changed the depends to reflect that.

We're also missing amaranth_boards, which without it's kind of hard to build anything real. I'm making do by just installing python-nmigen-boards (which seems happy "linking" to this package), but that uses the old style imports:

>>> from amaranth import *
>>> from nmigen_boards.mister import *

The check() fails for me. I guess there's some failures in the upstream tests:

I fixed it (for myself, though YMMV) by telling pikaur to tell makepkg to not run check(): --mflags=--nocheck

FWIW I don't think this should be changed in the PKGBUILD, you might still want to run tests, idk what the philosophy of check() is normally.
