Bitbake On Recipe Dependencies

This project provides tools that perform custom tasks or full build on a given recipe's dependencies which are recipes also.

What ?

The idea is the following:

1. Generate a recipe's dependencies list
2. Remove the recipe itself from the list to avoid bitbakeing it
3. Loop through the list and run the full or given task on the recipe

How ?

This project provide two scripts that do the same thing:

• bitbake-deps.sh: Can be ran from anywhere.
• bitbake-deps: Must be copied to poky/bitbake/bin to be able to use bitbake library

Shell Solution

• Usage:

./bitbake-deps.sh target [task]

The shell script provide a DEBUG level that you can activate by setting the variable ENABLE_DEBUG to 1:

ENABLE_DEBUG=1 ./bitbake-deps.sh core-image-minimal

When enabling DEBUG, bitbake output will be shown along side the [DEBUG] log message.

Python Solution

You need to copy the bitbake-deps script to poky/bitbake/bin and resource the oe-ini-build-env script again. Then you can use it like follows:

• Usage:

bitbake-deps --help
usage: bitbake-deps [-h] -r RECIPE [-t TASK]

Run Tasks on Dependencies

optional arguments:
  -h, --help            show this help message and exit
  -r RECIPE, --recipe RECIPE
                        Recipe name
  -t TASK, --task TASK  Custom task to run on deps

• Fetch all dependencies of core-image-minimal

bitbake-deps -r core-image-minimal -t do_fetch

Use case examples

• Fetch all dependencies of an image:

./bitbake-deps.sh core-image-minimal do_fetch

• Build all dependencies of a given package:

./bitbake-deps.sh virtual/kernel

TODO

• Complete the Python bitbake-dep script
