When trying to run kas-docker with --isar on podman the build fails
with some "exec format" errors when the target has a different
architecture than the host. The reason is that /proc/sys/fs/binfmt_misc
is not mounted as expected inside the container.

The way the /proc filesystem is mounted seems to differ between podman
and docker. See [1] for the podman issue tracker. This is a temporary
fix and should be removed when the upstream issue was resolved.

Setup tool for bitbake based projects

Branch Build Status
master travis-master
next travis-next

This tool provides an easy mechanism to setup bitbake based projects.

The OpenEmbedded tooling support starts at step 2 with bitbake. The downloading of sources and then configuration has to be done by hand. Usually, this is explained in a README. Instead kas is using a project configuration file and does the download and configuration phase.

Key features provided by the build tool:

  • clone and checkout bitbake layers
  • create default bitbake settings (machine, arch, ...)
  • launch minimal build environment, reducing risk of host contamination
  • initiate bitbake build process

See the kas documentation for further details.

You can’t perform that action at this time.
