Provides an easy means to work on developing applications and system components with the build system. For example to "modify" the source for an existing recipe: $ devtool modify -x pango /home/projects/pango Parsing recipes..done. NOTE: Fetching pango... NOTE: Unpacking... NOTE: Patching... NOTE: Source tree extracted to /home/projects/pango NOTE: Recipe pango now set up to build from /home/paul/projects/pango The pango source is now extracted to /home/paul/projects/pango, managed in git, with each patch as a commit, and a bbappend is created in the workspace layer to use the source in /home/paul/projects/pango when building. Additionally, you can add a new piece of software: $ devtool add pv /home/projects/pv NOTE: Recipe /path/to/workspace/recipes/pv/pv.bb has been automatically created; further editing may be required to make it fully functional The latter uses recipetool to create a skeleton recipe and again sets up a bbappend to use the source in /home/projects/pv when building. Having done a "devtool modify", can also write any changes to the external git repository back as patches next to the recipe: $ devtool update-recipe mdadm Parsing recipes..done. NOTE: Removing patch mdadm-3.2.2_fix_for_x32.patch NOTE: Removing patch gcc-4.9.patch NOTE: Updating recipe mdadm_3.3.1.bb [YOCTO #6561] [YOCTO #6653] [YOCTO #6656] (From OE-Core rev: 716d9b1f304a12bab61b15e3ce526977c055f074) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
