What program are you linking?
Does this happen all the time or when you link a specific program?

Getting closer!
libgcc_s.so is a script that requires libgcc.a (it wasn't clear from the mold error message). After adding the path to libgcc.a
mold -o a.out -L/usr/lib64 -ldl test2.o -L/usr/pkgs/gcc/12.1.0/lib64/ -lc -lstdc++ -lgcc_s -L/usr/pkgs/gcc/12.1.0/lib/gcc/x86_64-pc-linux-gnu/12.1.0/
mold: error: undefined symbol: test2.o: __dso_handle
Any ideas @rui314 ??

Can you rebuild mold with the above commit and try again?
gcflymoto commentedon Jul 11, 2022
Confirmed! Working now. Thank you so much.
I'm stuck on a build layer calling mold with -rdynamic.. but that's a separate issue I might workaround.
rui314 commentedon Jul 12, 2022
-rdynamicisn't a valid option for anyldcommand as a far as I know. It's an option for compiler drivers (e.g.cc,gcc, etc.)
