Using Docker to host ARM toolchain to cross-compile C code I'm starting up a project that will see me doing custom software development for an ARM single-board-computer running Linux. The recommendation isn't to do compiles ON the board, but instead to cross compile from a Linux workstation (Debian). But, I use a Mac laptop, as do most software engineers these days. While I could run VirtualBox to set up a Debian cross-compiling environment, Docker is much lighter weight. While Docker was originally targeted for deploying server applications, it is useful for packaging anything. In this case there's a ready-made set of Docker containers for cross-compilation including for ARM CPU's.
