Bug 787665 – app-emulation/wine-staging-6.7 USE=mingw fails with gcc 11.1 /usr/libexec/gcc/i686-w64-mingw32/ld: dlls/d2d1/brush.cross.o:brush.c:(.text+0x1baf): undefined reference to `sincos'

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Mike Lothian 2021-05-02 10:30:42 UTC]

wine-staging fails to be built with gcc / mingw 11.1, looks like the maths library isn't linked

Reproducible: Always

This might be related to https://bugs.gentoo.org/787662 the libraries might need to be rebuilt with gcc 11.1

[Comment 4 Mike Lothian 2021-05-02 19:52:17 UTC]

Rebuilding mingw64-runtime, didn't help, neither did adding it's work around

[Comment 5 Ionen Wolkens 2021-05-05 08:05:06 UTC]

Seems(?) to have something to do with gcc's builtins which include sincos. Guess gcc11 is doing something different in that regard (wine-vanilla also affected).

So, for another temporary workaround, adding -fno-builtin to CFLAGS should let it build.

[Comment 6 Mike Lothian 2021-05-05 09:43:58 UTC]

That workaround worked, cheers

[Comment 7 Ionen Wolkens 2021-06-11 21:24:31 UTC]

Haven't been able to reproduce this since wine-staging:6.9

I'll take the liberty to mark this obsolete.
