I don't even consider that to rise to the level of "cross compiling".

Getting started with emscripten to target WASM for C and C++ is rather a chore of dependency wrangling IME. Targeting WASM from Rust, OTOH, is trivial. Targeting windows from linux with Rust is also quite straightforward, as has been experimenting with targeting consoles or Android from Windows.

Targeting a MIPS32 OpenDingux target from Windows was much more of a chore. The toolchain with libs, headers, etc. that I used is just a *.tar.bz2 that expects to be extracted to /opt/gcw0-toolchain of a linux distro specifically, and embedded absolute paths all over the place make changing that difficult. I do resort to WSL on Windows, basically only because of those embedded paths: https://github.com/MaulingMonkey/rust-opendingux-test

Acquiring the appropriate libs and headers to link/compile against for cross compiling is always an adventure, but Rust isn't making things any worse IME.

Well, at least that's that easy if what you try to compile don't have C dependencies. For C dependencies, there is cross <https://github.com/japaric/rust-cross> which I had good experiences with.

Oh, this was the first thing that came up: https://github.com/japaric/rust-cross
