Cross compile arm64 on x86 arch

[vincentdchan]

Desired Behavior

Apple has released M1 sillicon for a while. It's inconvient to compile OCaml code for different platforms.
Such as compiling M1 version on a x86 mac, or compiling x86 on a M1 mac. Is that possible for OCaml?

Both Go and Rust support this feature.

It's possible. It does require you to install a host and target compiler though. See documentation: https://dune.readthedocs.io/en/stable/cross-compilation.html

I don't know how to choose the arch of target from the document you presented.
