Developing arm32 on x86

We recommend using qemu-multiarch to execute arm32 containers on x86 computers. will automatically detect the architecture and ask you if it should run multiarch/qemu-user-static.

Building arm32

Building on ci-platforms will require the same qemu/multiarch libs to be present. The sections below show, how to enable it for various platforms.

It is also required to add qemu-arm-static to /usr/bin/qemu-arm-static. This is already done in infracamp/kickstart-flavor-arm32v7-base.

Create a file hooks/pre_build, make it executable (chmod 755 hooks/pre_build).

# Register qemu-*-static for all supported processors except the
# current one, but also remove all registered binfmt_misc before
docker run --rm --privileged multiarch/qemu-user-static:register --reset
