This repository contain a script that will download and build cross compile tools that can cross compile Rust from macOS to FreeBSD.
It will also cross compile a hello world crate and execute on the remote machine.
This is not meant to be a solution that works for everyone out of the box but hopefully it can help you get started to create your cross compile environment.
A real or virtual FreeBSD 11 or 12 (10 or older is untested) machine.
A macOS computer.
For VirtualBox make sure you configure port forwarding so that you can ssh in to the machine.
Before running the script make sure to install brew and
rustup. You will be prompted if anything is missing.
Change the parameters in the top of build.sh to suite your system
then just type
./build.sh
in the checkout folder.
