Consider adding some WSL-specific help to README

First of all thank you! Very excited to start using this. There is a small gotcha I ran into because I use WSL environment. It will not run natively in it, you will need to cross-compile. It may be helpful to others?

Testing Locally with WSL

things to include in .cargo/config

[target.x86_64-pc-windows-gnu]
linker = "x86_64-w64-mingw32-gcc"
ar = "x86_64-w64-mingw32-gcc-ar"

This can work if you've got mingw sudo apt install mingw-w64 (there maybe better linkers but i didn't investigate) credit goes to these people: link

you may also need to add this target with rustup and the compiler will tell you if you don't have it

rustup target add x86_64-pc-windows-gnu

to see which targets you have run

rustup target list

Then compile to that target: cargo build --target x86_64-pc-windows-gnu Have your Rust directories somewhere easily accessible on both, WSL bash and on Windows file explorer: it will make you a clickable .exe file that works natively

The error you get if you let it think it's in real linux is here: Error: WinitEventLoop(Os(OsError { line: 81, file: "/home/xxxx/.cargo/registry/src/index.crates.io-6f17d22bba15001f/winit-0.29.9/src/platform_impl/linux/wayland/event_loop/mod.rs", error: WaylandError(Connection(NoWaylandLib)) })) I tested that a GUI is possible (there are some nuances depending if you have WSL1 or WSL2 link) and in my configuration a linux GUI can be successfully displayed from WSL.

I was also affected. Thanks for sharing.

Sadly I am getting:

I think I'll try running it on my Ubuntu laptop over the weekend.

[c-git]

@andreamancuso were you able to get through following the steps posted by the OP?

[andreamancuso]

I wasn't. I'll try again ASAP, likely in the morning (I am based in the CEST time zone).

[artavash]

Can you confirm you have a linker installed? Something like sudo apt install mingw-w64

Also it is probably worth executing the rustup command it suggests

[andreamancuso]

Good news.

You were right: as I am new to the Rust world, I didn't realize I was meant to run rustup target add x86_64-pc-windows-gnu. I then ran cargo build --target x86_64-pc-windows-gnu. Naturally I moved the folder into /mnt/c/<...> so I could easily access the generated .exe file.

Here's the end result:

Massive thanks for your help.

I should point out last night I managed to build both targets on my Ubuntu laptop flawlessly. I can't wait to get started with my project.

Awesome! I'll update the post to point out the rustup step.
