BREAKING CHANGE: This package now builds shared objects:

/usr/lib/libfolly.so
/usr/lib/libfolly_test_util.so
/usr/lib/libfollybenchmark.so

instead of the static libraries:

/usr/lib/libfolly.a
/usr/lib/libfolly_exception_counter.a
/usr/lib/libfolly_exception_tracer.a
/usr/lib/libfolly_exception_tracer_base.a
/usr/lib/libfolly_test_util.a
/usr/lib/libfollybenchmark.a

Downstream packages must move folly from the makedepends to depends array to stay functional.

We are doing this change since dynamic rather than static linking between packages is more in line with Arch Linux packaging practices (or just Linux packaging practices in general).

@ftiasch could you please add me as co-maintainer or update to 2025.06.16.00? All of these facebook tools generally assume they are at the same version level, so if you are okay with me co-maintaining it would make my life a lot easier

Thank you for maintaining the package!

For some people who are not familiar with the testing repositories, https://wiki.archlinux.org/title/Official_repositories#Testing_repositories

you can wait for the liburing>=2.10 to be on stable repositories.

I'm not sure it's OK to enable testing repositories even when you need to build the latest version now.

ftiasch commented on 2025-06-04 04:46 (UTC)

@envolution I successfully built and updated the package. Thanks for your help! I also listed you as a contributor.

envolution commented on 2025-06-04 03:51 (UTC)

by the way, testing has liburing 2.10 - https://archlinux.org/packages/extra-testing/x86_64/liburing/

I think it's fine to just require liburing>=2.10

envolution commented on 2025-06-04 03:41 (UTC)

@ftiasch I got it to compile with the following: https://github.com/envolution/aur/tree/main/abandoned/folly

Both patches changed, the cmake one I just changed the offset to match the current version

I left some comments about things that may not be needed, but my laptop takes too long to run through more full compilations to confirm. In any case it seems to compile happily now

Hi all. I managed to bump the version to v2025.06.02.00.

I first encountered an issue regarding of missing io_uring_zcrx_*. I found it was added in the commit, which in turn will appear in liburing-2.10. As the official package is for 2.9, changing the dep from liburing to liburing-git will fix this, for now.

Next, I struggled with some random errors relating to glog. I also found this issue, where the mentioned fixes already included in this package somehow stopped working. I can't figure out why, so I sincerely ask someone to help.

No worries - I did take a quick look and ran into at least one file missing from the release archive that exists in the git repo. You may find cloning the version tag a requirement to get it to build

using release folly-2025.06.02.00.tar.gz for reference:

@envolution I can try to fix it. But it's been a long time since my last commit. It may take me sometime to figure out why.

  • The cmake 4 incompatibility is addressed in update 2025.06.02 -

This fails for me:

                 from folly/ProactorExecutor.cpp:17:

Apparently _Py_IsFinalizing is depreciated

It looks like it needs https://github.com/facebook/folly/pull/2360 to build
