Given your tendency to hit issues, can I suggest: PORTAGE_ELOG_CLASSES="warn error info log qa" PORTAGE_ELOG_SYSTEM="echo save" PORTAGE_LOGDIR="/var/log/portage" FEATURES="${FEATURES} clean-logs split-log" in make.conf, to preserve them?
(also, emerge --info please, it does matter)
Does it still fail if you disable custom-cflags? That old -fno-builtin workaround should be obsolete and may instead be causing issues. Also given I see crossdev-mingw, what version of mingw64-runtime? (if it doubt, you can turn that off and mingw64-toolchain should work).
I've not tested that yet I added it for wine-staging and that still builds fine mingw64-runtime 10.0.0-r1 I installed wine-proton to see if Ubi Connect would run and it does (it doesn't under wine-staging) Will add better logs and a few tests once I'm finished
Yeah, tried and this is caused by -fno-builtin mingw builds are sensible to the way gcc optimize stuff, can lead to different functions being used like gcc changing sin and cos to sincos() despite mingw didn't have sincos (bug #787665). I assume similar is happening here and unexpectedly end up needing libm because the builtin is disabled. Given -fno-builtin is rather obscure I don't think it makes sense to strip it in the ebuild (not done by strip-flags unfortunately), please just remove it. (In reply to Mike Lothian from comment #4) > I installed wine-proton to see if Ubi Connect would run and it does (it > doesn't under wine-staging) Sounds like that may(?) be using the bcrypt stuff (with libgcrypt), it used to be in wine-staging but got removed (still present in proton). Not that I really read the story here.
Confirmed, dropping -fno-builtin gets things working without adding -lm Thanks The Ubi Connect bug I think is in dxgi or one of the directx libraries
