Now that .bbclass is removed from class section titles. We can now have, for example, :ref:`ref-classes-insane` instead of :ref:`insane <ref-classes-insane>`. Then, when necessary, rework paragraphs so that they have lines of even length, not exceeding 80 characters.

Conserving Disk Space
|
|
*********************
|
|
|
|
Conserving Disk Space During Builds
|
|
===================================
|
|
|
|
To help conserve disk space during builds, you can add the following
|
|
statement to your project's ``local.conf`` configuration file found in
|
|
the :term:`Build Directory`::
|
|
|
|
INHERIT += "rm_work"
|
|
|
|
Adding this statement deletes the work directory used for
|
|
building a recipe once the recipe is built. For more information on
|
|
"rm_work", see the :ref:`ref-classes-rm-work` class in the
|
|
Yocto Project Reference Manual.
|
|
|
|
Purging Duplicate Shared State Cache Files
|
|
==========================================
|
|
|
|
After multiple build iterations, the Shared State (sstate) cache can contain
|
|
duplicate cache files for a given package, while only the most recent one
|
|
is likely to be reusable. The following command purges all but the
|
|
newest sstate cache file for each package::
|
|
|
|
sstate-cache-management.sh --remove-duplicated --cache-dir=build/sstate-cache
|
|
|
|
This command will ask you to confirm the deletions it identifies.
|
|
|
|
.. note::
|
|
|
|
The duplicated sstate cache files of one package must have the same
|
|
architecture, which means that sstate cache files with multiple
|
|
architectures are not considered as duplicate.
|
|
|
|
Run ``sstate-cache-management.sh`` for more details about this script.
