>checking whether pthreads work without any flags... yes I can't reproduce, but comparing with my own configure output this is where it diverges. Mine fails this test, and later appropriately adds -pthread flag. Your config.log may have a hint as to what happened, i.e. /var/tmp/portage/net-libs/libasyncns-0.8-r4/work/libasyncns-0.8-abi_x86_64.amd64/config.log or so

Could you please try without your set LDFLAGS too? And depclean/select newer binutils?

Seem to be two things needed to reproduce this. 1. have libnsl installed (checks for it but discarded by --as-needed) 2. LDFLAGS="-Wl,--copy-dt-needed-entries" I guess #2 copies libnsl's needed and misleads configure into thinking it doesn't need -pthread.

I removed previous and other versions of binutils: # eselect binutils list [1] x86_64-pc-linux-gnu-2.36.1 * # but the error is still here after source /etc/profile and remerge. I don't understood the sentence about LDFLAGS, trying to figure out it.
(In reply to Einstok Fair from comment #10) > I don't understood the sentence about LDFLAGS, trying to figure out it. You appear to be setting LDFLAGS="-Wl,--copy-dt-needed-entries" somewhere, likely in your /etc/portage/make.conf or similar. Is it your intention to set this? The idea would be to remove this and use defaults.
Without LDFLAGS it compiles, but i don't remember why I did added that flag globally (probably removing it will break something else).

You shouldn't need it at all but *if* you do: 1. let's investigate it together 2. let's set it per-package via package.env (https://wiki.gentoo.org/wiki//etc/portage/package.env#Example_1:_Enable_debug_information_for_a_specific_package)
