Description Arusekk 2024-09-30 08:59:31 UTC

If mold linker is used, it fails due to an unsupported command-line option --copy-dt-needed-entries. The flag is being added by the Gentoo ebuild, the comment says "Fix building tests".

Reproducible: Always

Steps to Reproduce:
1. Set up mold like in the Gentoo Wiki https://wiki.gentoo.org/wiki/Mold
2. Try to emerge media-gfx/freecad-1.0_rc1-r1
Actual Results:  
mold: fatal: unknown command line option: --copy-dt-needed-entries
collect2: error: ld returned 1 exit status

Expected Results:  
Package installs.

Someone from mold community says this --copy-dt-needed-entries is useless: https://github.com/rui314/mold/issues/530

Clearly it is not useless since it does fix an issue here
