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).

@envolution I can confirm it is fixed now. Thanks very much!

envolution commented on 2025-07-24 19:28 (UTC)

@Winterreise i've fixed those pyside2 packages as I maintain those - can you try update and install this package once more?

Winterreise commented on 2025-07-23 07:19 (UTC)

@envolution: Thanks for indication a way to find the problem. Yes I do find two broken name by your script:

Broken package (no name): /usr/lib/python3.13/site-packages/shiboken2.egg-info
Broken package (no name): /usr/lib/python3.13/site-packages/PySide2.egg-info

@Winterreise this one is difficult to troubleshoot as I suspect you have some broken python metadata in site-packages. Have you had trouble installing other aur python packages using setuptools?

You can try find the offending packages with the following python snippet

#!/usr/bin/env python3
import importlib.metadata
for dist in importlib.metadata.distributions():
    name = dist.metadata.get('Name')
    if name is None:
        print(f"Broken package (no name): {dist._path}")

Fail to build folly, but I can't find anything in the search engine to solve this problem:

/usr/lib/python3.13/site-packages/setuptools/__init__.py:92: _DeprecatedInstaller: setuptools.installer and fetch_build_eggs are deprecated.

@jghodd thanks, I've dropped the CXX flags as they seem to no longer be necessary

jghodd commented on 2025-07-11 03:37 (UTC)

@envolution - seems that dropping the following compiler flag does the trick:


-DCMAKE_CXX_FLAGS="-mpopcnt -mbmi -mbmi2 -ltbb"

jghodd commented on 2025-07-10 19:33 (UTC)

@envolution - I'm going to say no. I'm on an AMD A8 quad-core that I'm sure predates 2017. I also saw this in the config output:

-- arch matches x86_64, setting SSE2/AVX2 compile flags for LtHash SIMD code

which concerned me, given that my processor does not support AVX2 - AVX, but not AVX2. It does support popcnt, though, so I will try a build removing the flag line you suggested.

@jghodd - I had made a note when adding some compile flags - does your cpu meet the minimums listed here?

intel haswell(gen4+) 
amd circa 2017+

that cmake flag you mentioned is specific to rdkit and probably won't do anything differently here for you. try remove the line: -DCMAKE_CXX_FLAGS="-mpopcnt -mbmi -mbmi2 -ltbb" \ in the build section to see if that helps

envolution commented on 2025-07-10 18:51 (UTC)

@jghodd sorry I didn't notice your comment was updated - you can find the built zst files at https://github.com/envolution/aur/releases?q=folly&expanded=true . It is a highly optimised library /but/ is supported on macos so nothing limiting it to to the intel platform.

I'll take a look at your logs to see if I can make sense of the errors
