I didn't test the full Wine build. I don't who/which program needs opus. But it's not working anyway, so I would be fine with the patch. I could not apply the patch. Maybe I did something wrong on my side? Anyway, it's so short, I "applied" it manually. Then it looks good: $ ./pre-inst-env guix environment -C --expose=/gnu/store/ --ad-hoc wine -- wine $(./pre-inst-env guix build hello --target=i686-w64-mingw32)/bin/hello.exe [... some wine error message I suppose to be due to the -C environment ...] Hello, world! Guix is so cool :-) Thanks, Björn
