This error doesn't come from emacsclient, it comes from the async

GCC and/or Binutils?

I have been using the same gcc and ld versions for few years now.

See? it's ld, the linker, complaining that it cannot find a library
(libgcc) it needs for producing the .eln file.

But it works in non-daemon mode i.e. if I run emacs instead of emacsclient.

 

You should verify your libgccjit installation is working correctly.
Which GCC version do you have?

9.3.0

Also please see the attached screenshot. I am showing there the the libgccjit.so should have been found (it is anyways found correctly when I run non-daemon emacs).

 

FWIW, I have no problems building the current emacs-29 branch with
native-compilation.

Same here. The build finishes successfully. The problem shows when I launch emacsclient.

 

  I just tried.

This is not the latest emacs-29 branch, btw (not that I expect a
slightly outdated revision of the branch to fail to compile).

I just rebuilt emacs with --bootstrap now this error is gone!

It looks like I landed on an intermediate commit while this issue existed around 05/12. But as of the c18f9f155f6a commit, this issue is gone.

Thank you for looking into this!

This issue can be closed.
