Cross Compiling

SurfaceRT or RT2 is ARMv7 (ARM32 / armhf ) Cross compiling is fairly simple when using docker, but you can do it it without.

Cross compiler quick setup (platform agnostic mac/linux/windows)

Linux: apt install docker Mac: brew install docker; brew cask install docker; Windows (install docker-ce from docker run --rm dockcross/linux-armv7:latest > dockcross-linux-armv7-latest chmod +x dockcross-linux-armv7-latest To use:

./dockcross-linux-armv7 bash -c make

Alternate option (linux debian based - amend for other package managers as needed)
