External Buildroot Packages #998

Closed amclain closed 1 month ago

amclain commented 1 month ago

Related to: nerves-project/nerves_system_br#806

This PR allows a Nerves system maintainer to add external Buildroot packages to a Nerves system so that Buildroot can be extended without forking nerves_system_br. External Buildroot customizations are explained in section 9.2 of the Buildroot manual. Since Nerves sets BR2_EXTERNAL and controls the build process, this PR discovers Elixir dependencies with the project setting buildroot_package: true and adds them to the BR2_EXTERNAL variable.

Thanks for this PR. It's clear that some documentation is missing. You can already add Buildroot packages without forking nerves_system_br, though. See https://github.com/nerves-project/nerves_system_bbb/tree/main/package/extra-dts for a really simple example, but hopefully it gives an idea about how you can add to the external menu.

@fhunleth that example is within the BBB Nerves system though, right? We're looking to add a library that can be included across multiple Nerves systems that adds to the Buildroot menu. A good example is like what nerves-config does, if it were maintained outside of the Nerves tooling. I'm also happy to give you a walkthrough of what we're doing.

Let's move this to #nerves-dev. I think there's a lot to discuss on the topic and I'm not sure if the fidelity of GitHub comments will make it easy.

As discussed, we'll keep the new menus in the Nerves systems for now. Thanks!
