Documentation
This is the directory that contains the BitBake documentation.
Manual Organization
Folders exist for individual manuals as follows:
- bitbake-user-manual --- The BitBake User Manual
Each folder is self-contained regarding content and figures.
If you want to find HTML versions of the BitBake manuals on the web, go to https://www.openembedded.org/wiki/Documentation.
Sphinx
The BitBake documentation was migrated from the original DocBook format to Sphinx based documentation for the Yocto Project 3.2 release.
Additional information related to the Sphinx migration, and guidelines for developers willing to contribute to the BitBake documentation can be found in the Yocto Project Documentation README file:
https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/tree/documentation/README
How to build the Yocto Project documentation
Sphinx is written in Python. While it might work with Python2, for obvious reasons, we will only support building the BitBake documentation with Python3.
Sphinx might be available in your Linux distro packages repositories, however it is not recommend using distro packages, as they might be old versions, especially if you are using an LTS version of your distro. The recommended method to install Sphinx and all required dependencies is to use the Python Package Index (pip).
To install all required packages run:
$ pip3 install sphinx sphinx_rtd_theme pyyaml
To build the documentation locally, run:
$ cd documentation $ make -f Makefile.sphinx html
The resulting HTML index page will be _build/html/index.html, and you can browse your own copy of the locally generated documentation with your browser.
