Excerpt from the build.log:

147:26.13 /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld.bfd: /usr/lib/libz.a(gzlib.o): in function `snprintf':
147:26.14 /usr/x86_64-w64-mingw32/usr/include/stdio.h:441: undefined reference to `__mingw_vsnprintf'

I cannot figure out why mingw should appear here.

That is very weird. I have a mingw64 compiler installed with crossdev as described here: https://wiki.gentoo.org/wiki/Mingw . But I have no idea why this is happening, it shouldn't be using mingw at all.

I'll try recompiling with USE="+clang"

[Comment 5 Sam James 2021-10-15 04:09:50 UTC]

Can you please run:
- emerge -v1 sys-libs/zlib /usr/lib/libz.a
- wgetpaste /usr/x86_64-w64-mingw32/usr/include/stdio.h

Could you also please try to install via a clean root environment (not via sudo) or try with env -i?

The first command gives me the following:

I had to install the libz and libpng libraries myself to get SDL_Image working with mingw64. I basicially just followed the instructions here: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=mingw-w64-zlib

It looks like I have a bunch of *.a and *.dll.a files in my /usr/lib and /usr/libexec. should I remove those? I think I may have accidentally put those there.

>libanl.a
>libBrokenLocale.a
>libc.a
>libc_nonshared.a

I tried re-emerging with su and env -i, but it failed so I uploaded that build log too.

Okay I deleted the files with `rm $(qfile -o /usr/lib/*)` and `rm $(qfile -o /usr/libexec/*)` and firefox built fine. sorry about that.
