there's something wrong with wine through qemu.

updated to wine 8.0.2, same error message

is-it-ayush commented 8 months ago

Hi @Emilgardis! I ran into this exact problem and my problem output matched the one in this issue. After updating cross to main & trying cross run --target x86_64-pc-windows-gnu again. I got the following error wine: '/tmp/wine' is not owned by you.

It seems like the permissions aren't setup correctly on ghcr.io/cross-rs/x86_64-pc-windows-gnu image. I did some extra digging and ran docker run --platform linux/amd64 --rm -t -i ghcr.io/cross-rs/x86_64-pc-windows-gnu:main bash and then ls -all /tmp/wine. It gives,

drwxrwxrwx  2 root root    0 Dec  9 01:34 .wine-0
drwxrwxrwx  2 root root    0 Dec  9 01:34 home
drwxrwxrwx  4 root root 4096 Dec  9 01:34 wine

However, running cross run --target x86_64-pc-windows-gnu -vvv gives the folllowing string /usr/bin/docker run --userns host ... -e 'USER=ayush' -e ... --rm --user 1000:1000 ... (... = i've left out the env vars since they were long!). I feel it's trying to run cargo under my machine username but wine is owned by root. If this is the case any ideas on how I can go about working around it until it's fixed. Thank you for working on it.

Update! Turns out it wasn't really an image issue but an issue of how my docker files were stored. The docker daemon data-root directory wasn't owned by me. I replaced it with another location (ext4 partition new /docker folder) & restarted docker. The error does not occur now and I think I've resolved it. Thank you : )

Ah perfect @is-it-ayush !

I suppose cross test doesnt work though?

is-it-ayush commented 8 months ago

That's true @Emilgardis! It does not work since the target defaults to ghcr.io/cross-rs/x86_64-unknown-linux-gnu & rust would not compile there since I used windows specific crates.

ps: Just wanted to thank you for this project. It helps a ton with cross compilation. Have an awesome day Emil!

Emilgardis commented 8 months ago

sorry, I should've specified, cross test --target x86_64-pc-windows-gnu shouldn't work under qemu emulation still because wine doesn't work correctly there

is-it-ayush commented 8 months ago

Just ran cross test --target x86_64-pc-widnows-gnu Emil! It doesn't crash and runs tests successfully but I do get strange output when running it. Here's an example!

are you on a aarch64/arm64 host? @is-it-ayush

I'm on amd64 (running debian 12) host @Emilgardis!

Emilgardis commented 8 months ago

I see, this issue is specifically for hosts where emulation would be used to run x86_64!

Makes sense!! I think it's more of a wine issue than a cross issue. 😅
