Based on the Miyoo Mini Union toolchain Docker image. The toolchain and sysroot files used here are originally here.
With Docker installed and running, make shell builds the toolchain and drops into a shell inside the container. The container's ~/workspace is bound to ./workspace by default. The CROSS_COMPILE and PATH env vars have been updated with the toolchain location.
After building the first time, make shell will skip building and drop into the shell.
- On your host machine, clone repositories into
./workspaceand make changes as usual. - In the container shell, find the repository in
~/workspaceand build as usual.
Docker for Mac has a memory limit that can make the toolchain build fail. Follow these instructions to increase the memory limit.
