Arch Linux User Repository

@soloturn I’m leaning towards a buck2 package because “buck2” seems to be how upstream has named the product. That would also be consistent to the existing buck2-git AUR package.

Once a stable release of buck2 comes out, I’m going to create the package – unless someone else wants to take it on.

buck2 is released, would you prefer to update the existing buck package, or better create a buck2 package?

@jc65536 Thanks for the pointer. I just pushed an update, bumping the version to v2021.05.05.01 (the folks at Meta appear to have forgotten that it’s 2022.) The Java 8 issue should be fixed now.

Thanks @Auerhuhn. Another issue I encountered was that buck was unable to find a "system compiler." I think the dependency should be changed from jre8-openjdk-headless to jdk8-openjdk.

Thanks for the pointer @jc65536. I just pushed an updated PKGBUILD, which should include workarounds for the Python 3.10 issues.

I also replaced the Python 2 dependency with Python 3. The package works for me now so chances are it’s working now for you, too.

Hi, this package is failing to build:

command: [/usr/bin/python3, /home/jason/.cache/yay/buck/src/buck-2021.01.12.01/ant-out/buck-modules-resources/python/make_pex.py, --python-shebang=/usr/bin/env python3, --python, /usr/bin/python3, --python-version, CPython 3.10, --entry-point, programs.gen_buck_info, buck-out/gen/ce9b6f2e/programs/gen_buck_info.pex]

stderr: Traceback (most recent call last):

Is the build file using Python 3 where it should use Python 2?

I have taken over the package, bumped to the latest version and added a workaround for the issue @sramey40 reported.

Hi @kendfinger, this package needs a version bump and a couple of fixes. Would you mind adding me as a co-maintainer? Alternatively, feel free to pick the relevant commits from my fork on GitHub. Thanks in advance!

The latest update is currently broken, due to a bug in how the Buck installer works. I have filed a bug against the Buck repository at https://github.com/facebook/buck/issues/2462 and a fix at https://github.com/facebook/buck/pull/2463.

In the meantime, you'll need to either:

1. Modify programs/gen_buck_info.py to remove lines 55-56 (which cause the infinite loop described in the installer bug), OR
2. Add a .git folder in the extracted source of the Buck repository that contains the revision history of Buck (the installer searches for this to generate the Buck version).

To do (1), apply the following patch to the PKGBUILD:

diff --git a/PKGBUILD b/PKGBUILD

You not only need to install a java 11 environment, but also activate it, e.g.

archlinux-java set java-11-openjdk

as root. I doubt if yay can be configured to do this, so please try with plain makepkg.
