I recently discovered Yocto. I'm able to successfully build an image using the command bitbake fsl-image-gui. But now, I would like to browse the code, the project specific code and the Kernel code for the fsl-image-gui but I cannot figure how ?
Where is the source code when I build my Yocto project and how could I browse it ?
There are two halves of the Yocto setup:
sources/ directory, containing the bitbake recipes and supporting configuration, andbuild/ directory, where the actual builds take place.Each of the bitbake recipes (i.e. *.bb files found in a structure under the sources/ directory) that you run should be constrained to a directory structure like:
build/
tmp/
work/
< platform name >/
< recipe name >/
< version >/
...juicy stuff here...
Underneath the < version >/ directory, you should find a structure like:
build/
image/
package/
packages-split/
temp/
your_unpacked_source_directory/
...and others
...where your_unpacked_source_directory is determined by the directory structure contained in the downloaded and unpacked source. (e.g. as contained in the .tgz file)
All of the build logs and scripts generated during the build are contained in the temp/ directory.
The package/ directory contains all of the files that are to be packaged as a result of this recipe. The packages-split/ divides the files into their separate packages, e.g. base package, -dev package, -dbg package, -staticdev package.
Well, have you looked around in the build tree?
You'll have a downloads directory, in which all downloaded tarballs are stored, as well as all cloned repositories.
The actual unpacking and building takes place in subdirectories under build/tmp/work/<arch>/.
