uv-Python build fail due to missing libatomic.a on arch #3474
Description
Nuitka and Python version:
2.7.3
Commercial: None
Python: 3.11.11 (main, Mar 17 2025, 21:02:09) [Clang 20.1.0 ]
Flavor: Python Build Standalone
Executable: ~/.cache/uv/archive-v0/d47QaPIKtn6EVRot-tWZw/bin/python
OS: Linux
Arch: x86_64
Distribution: Arch None
Version C compiler: /usr/lib/ccache/bin/gcc (gcc 15.1.1).
There are no packages involved. Even a simple hello world crashes.
print("Hello World")The problem is that (probably in the new gcc 15 update) libatomic.a is not included in any way. This causes both dynamic and static libpython builds to fail on Arch.
I also tested on develop and factory branches and those fail as well as the current latest. (2.7.3)

Turns out, it might be uv instead of arch here
kayhayen commentedon May 19, 2025
Please don't be shy to provide more output, esp. from --show-scons, but indeed "Python Build Standalone" doesn't do or default to --static-libpython and issues a call to action warning to fix them. At some point in the future, it's probably going to work starting with some newer uv-Python versions.
Until this time it's a duplicate of #3331 for which I am closing this.

can confirm that in my case (red hat 8.9) using uv python leads to the error
/usr/bin/ld: cannot find -l:libatomic.abut if you install python normally (or in my case used the old install - python3.6) it works fine.
