gn is a commonly used build tool to generate ninja files, used in a lot of recipes e.g. chromium, qtwebengine, perfetto, hafnium etc. these recipes come from different layers e.g. meta-qt6/meta-arm/meta-oe since not all layers depend on meta-oe ( meta-arm does not ), its not a possible option. Given the usecases, putting it in core will benefit the ecosystem and reduce some duplication. This recipe is taken from meta-arm Signed-off-by: Khem Raj <raj.khem@gmail.com> --- meta/conf/distro/include/maintainers.inc | 1 + meta/recipes-devtools/gn/gn_git.bb | 46 ++++++++++++++++++++++++ 2 files changed, 47 insertions(+) create mode 100644 meta/recipes-devtools/gn/gn_git.bb
