[Pkg-rust-maintainers] Bug#989844: Bug#989844: Cross-compilation support (please package more libstd-rust-dev-*)

[Ximin Luo]

Hi,

Note it's already possible to cross-compile to other linux libc platforms, just dpkg --add-architecture $foreign then apt-get install libstd-rust-dev:$foreign.

Yes the *only* thing you have to do is package the libstd. I am unlikely to have time for the other platforms you mentioned but am happy to accept patches - just take a look at how the windows/wasm32 stuff how is done in the packaging and copy that. There is also the difficulty in testing the cross-compiled binaries, I personally don't have any Apple systems to test them on, whereas for windows/wasm32 there are emulators you can directly run on Debian.

Best,
Ximin
