Arch Linux User Repository

Facebook introduced a dependency to fb303, fbthrift and mvfst in edencommon in March. This means that building watchman + deps from source will take an incredibly long time.

I might try to patch out that dependency in the future (if possible), I published this now as a reference point for that endeavor. In the meantime, feel free to use watchman-bin if the compile times are problematic.

I needed to use the Homebrew workaround. https://github.com/facebook/watchman/issues/1186 Otherwise, building from Make files seems to take an awfully long time.

I'm getting this error

@carsme problem solved thanks

@kusoneko, I can't reproduce that issue. Can you try rebuilding folly and edencommon and see if the issue persists?

2023.09.04.00-1 doesn't compile on my end; I get the following error:

@carsme Thank you, works smoothly now for me :)

@AlexBocken I've excluded what I think are the problematic tests now. Let me know if you experience any other issues.

@carsme Rebuilt it again, same four checks failed. Note that I'm not building in a clean chroot.

@scarleo This happens if you have rustup instead of rust installed and not yet set a default toolchain. I've added a environemnt variable that will select the stable toolchain in these situations, as recommended by https://wiki.archlinux.org/title/Rust_package_guidelines. The package should build for you now without having to do rustup default stable (though you might want to do that anyway).

@AlexBocken I've noticed that some of the tests are failing intermittently. I'm trying to identify which these are since I would still like to perform testing in the package, if viable. Could you try re-building and see if the same tests fail again?
