Subject: Re: MUSL 5.2.0 Static linking issue
I've CC'd the musl list which I think you intended to do; your
original cc was to musl-admin rather than musl so it didn't make it to
the list.

Can you show the actual error you're getting?

Using ld directly is not expected to work unless you reproduce all the
options the compiler driver (gcc) would pass to it; the main place you
_might_ want to invoke ld directly is when doing
freestanding/bare-metal development, but musl is not going to be
useful for this out of the box; you'd need to customize it to your
environment. I can't tell from your email exactly what you're trying
to do, though.
