Details

Description: When building Godot using Pyston, Clang, and LLD, there is an error that prevents building:

/usr/bin/ld: cannot find -l:libatomic.a: No such file or directory
clang-14: error: linker command failed with exit code 1 (use -v to see invocation)
scons: *** [bin/godot.linuxbsd.editor.x86_64.llvm] Error 1
scons: building terminated because of errors.

I think this is caused by extra/libatomic_ops being built with shared libraries rather than static ones.
I solved it by building libatomic_ops with these steps: https://github.com/godotengine/godot/issues/46375#issuecomment-1373075734
The official Godot Game Engine linux compilation instructions are here: https://docs.godotengine.org/en/latest/development/compiling/compiling_for_linuxbsd.html#using-clang-and-lld-for-faster-development

Additional info:
* extra/libatomic_ops 7.6.14-1

Steps to reproduce:
- Build Godot using: scons platform=linuxbsd use_llvm=yes use_lld=yes
This task depends upon

I should also mention that this occurs with Godot master branch: https://github.com/godotengine/godot

Did you disable use_static_cpp? https://github.com/godotengine/godot/blob/master/platform/linuxbsd/detect.py#L403

When I disabled use_static_cpp, building completes successfully. However, I would like to have it enabled so the resulting binaries are more portable. I am unsure about other distros, but Fedora's libatomic-static package includes libatomic.a: https://github.com/godotengine/godot-docs/pull/5376

Arch policy is to only package dynamic libraries where both are available unless the static library is required by a package in the official repositories.

Oh okay, that makes sense.
