[Comment 4 Sergei Trofimovich (RETIRED) 2020-08-12 17:26:55 UTC]

config.log says you have enabled --enable-threads=posix.

Looking at our toolchain.eclass It should not be: https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/toolchain.eclass#n936

For 2 reasons:
- it's a cross-compiler targets
- and it's a mingw target

Did you patch or override things locally? We need to find out where it comes from.

[Comment 5 Jeremy Sylvis 2020-08-12 17:38:13 UTC]

I was following this guide: https://wiki.gentoo.org/wiki/DXVK#From_source

The command immediately after the initial crossdev command was this:
echo "EXTRA_ECONF=\"--enable-threads=posix\"" >> /etc/portage/env/mingw-gcc.conf

So, if I'm understanding the toolchain right (and I'm new, I'm likely not), if the first run-through may have failed for something unrelated, this echo would have added the --enable-threads flag, and subsequent runthroughs would fail.

I'll purge those and try again.

[Comment 6 Jeremy Sylvis 2020-08-12 18:09:35 UTC]

That was exactly the issue. Thank you for the guidance and my apologies for wasting your time.

I'll update the wiki to provide some guidance for anyone else who gets stuck there and close this.
