lld doesn't need LLVMgold at all, if this problem occurs it means that bfd is actually used.

Thanks, I had a problem in the build system that went unnoticed. I appreciate your time.

@enetheru Can you please share what was wrong, I have same issue.

[enetheru]

OK, so my memory is not great, last week was a year ago to me. But I remember vaguely that my toolchain was not setup properly, I was tracing commands from verbose output and found that it wasnt even doing what I told it to. I'm sorry I cant be more helpful. I've completely re-built my environments since then and dont remember the exact issue.

@CycloneRing I have the same issuee. How did you manage to fix it?

[enetheru]

@CycloneRing @hwalinga In my case I didnt fix it. After reading a bunch more, and testing out other build chains, I just stopped trying to use llvm clang in msys2/ucrt64. I change to msys2/clang64 when I want to compile using the llvm tools.
