These left me intrigued and thinking it'd be fun to update my media pipeline with some rust tooling. + +Starting the journey on my Arch Linux system despite the lead-in with the windows announcement. + +#### Cross Compilation + +Today I learned how to do cross compilation, which is super nice since my use cases find me potentially wanting to execute my code on either x64 linux, armv7, or windows. + +1. List targets with: + + `> rustc --print target-list` + +2. Add the desired target + + `> rustup target add ` + +3. Add (if not already installed) the cross package + + `> cargo install cross` + +4.
