Arch Linux User Repository

I have taken over the package and it will now compile correctly without Buck itself.

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
index 3575894..1b3d161 100644

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.

The build is broken. I'm not sure if it's this package, or an issue with the buck code itself. But the java compiler is having issues.

EDIT: So, I tried manually building from cloning the git repo. I have the exact same issue. Submitted github issue here

Error making: buck

I have taken over the package and it will now compile correctly without Buck itself.

Buck calls buck to build it (or I guess check if it's running?) this means it can't be built on machines that don't have a buck command already.

/home/justin/aur/buck/PKGBUILD: line 21: buck: command not found ==> ERROR: A failure occurred in build(). Aborting...

Fixed dependencies.

This package fails to build in a clean chroot with devtools since it apparently requires Java 8 to build but this dependency is not expressed properly in makedepends, causing pacman’s automatic selection to install a different version. Additionally, python is apparently also needed at buildtime (without it I get a build failure with error /build/buck/src/buck-2018.06.25.01/build.xml:889: Execute failed: java.io.IOException: Cannot run program "python" (in directory "/build/buck/src/buck-2018.06.25.01"): error=2, No such file or directory).

I added a prepare function to detect java version.

Indeed, just figured it out myself.

Problem identified after some more searching with different errors than previously. Buck needs JDK8. Later have some features it uses removed.
