Release 5.1 (styhead)
|

=====================

Migration notes for 5.1 (styhead)
|
|
------------------------------------
|
|
|
|
This section provides migration information for moving to the Yocto
|
|
Project 5.1 Release (codename "styhead") from the prior release.
|
|
|
|
.. _migration-5.1-supported-kernel-versions:
|
|
|
|
:term:`WORKDIR` changes
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
S = ${WORKDIR} no longer supported
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
If a recipe has :term:`S` set to be :term:`WORKDIR`, this is no longer
|
|
supported, and an error will be issued. The recipe should be changed to::
|
|
|
|
S = "${WORKDIR}/sources"
|
|
UNPACKDIR = "${S}"
|
|
|
|
Any :term:`WORKDIR` references where files from :term:`SRC_URI` are referenced
|
|
should be changed to :term:`S`. These are commonly in :ref:`ref-tasks-compile`,
|
|
:ref:`ref-tasks-compile`, :ref:`ref-tasks-install` and :term:`LIC_FILES_CHKSUM`.
|
|
|
|
:term:`WORKDIR` references in recipes
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:term:`WORKDIR` references in other recipes need auditing. If they reference
|
|
files from :term:`SRC_URI`, they likely need changing to :term:`UNPACKDIR`.
|
|
These are commonly in :ref:`ref-tasks-compile` and :ref:`ref-tasks-install`
|
|
for things like service or configuration files. One unusual case is
|
|
``${WORKDIR}/${BP}`` which should probably be set to ``${S}``.
|
|
|
|
References to ``../`` in :term:`LIC_FILES_CHKSUM` or elsewhere may need changing
|
|
to :term:`UNPACKDIR`. References to :term:`WORKDIR` in ``sed`` commands are
|
|
usually left as they are.
|
|
|
|
General notes
|
|
^^^^^^^^^^^^^
|
|
|
|
Files from :ref:`ref-tasks-unpack` now unpack to ``WORKDIR/sources-unpack/``
|
|
rather than ``WORKDIR/``.
|
|
|
|
If :term:`S` is set to a subdirectory under :term:`WORKDIR` and that
|
|
subdirectory exists in ``sources-unpack`` after :ref:`ref-tasks-unpack` runs,
|
|
it is moved to :term:`WORKDIR`. This means that ``S = "${WORKDIR}/${BP}"``,
|
|
``S = "${WORKDIR}/git"`` and also deeper paths continue to work as expected
|
|
without changes. We cannot use symlinks to do this as it breaks autotools
|
|
based recipes. Keeping all sources under ``sources-unpack`` wasn't considered
|
|
as it meant more invasive recipes changes. The key objective was separating the
|
|
:ref:`ref-tasks-unpack` task output from :term:`WORKDIR`.
|
|
|
|
Previously, :term:`S` was always created but after the recent changes it is no
|
|
longer the case. This means the check in ``do_unpack_qa`` triggers where
|
|
:term:`S` is not created by a recipe while it didn't happen before. This can
|
|
require to add an :term:`S` definition to a recipe that only uses
|
|
``file://`` :term:`SRC_URI` entries. To be consistent, the following pattern is
|
|
recommended::
|
|
|
|
S = "${WORKDIR}/sources"
|
|
UNPACKDIR = "${S}"
|
|
|
|
Building C files from :term:`UNPACKDIR` without setting :term:`S` to point at
|
|
it does not work as the debug prefix mapping doesn't handle that.
|
|
|
|
``devtool`` and ``recipetool`` have been updated to handle this and their
|
|
support for ``S = WORKDIR`` and ``oe-local-files`` has been removed.
|
|
|
|
Supported kernel versions
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The :term:`OLDEST_KERNEL` setting is still "5.15" in this release, meaning that
|
|
out the box, older kernels are not supported. See :ref:`4.3 migration notes
|
|
<migration-4.3-supported-kernel-versions>` for details.
|
|
|
|
.. _migration-5.1-supported-distributions:
|
|
|
|
Supported distributions
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Compared to the previous releases, running BitBake is supported on new
|
|
GNU/Linux distributions:
|
|
|
|
On the other hand, some earlier distributions are no longer supported:
|
|
|
|
See :ref:`all supported distributions <system-requirements-supported-distros>`.

.. _migration-5.1-misc-changes:
|
|
|
|
Miscellaneous changes
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
- `oe-selftest` now only rewrites environment variable paths that absolutely
|
|
point to builddir (i.e ``X=$BUILDDIR/conf/`` is still rewritten to point to
|
|
the `oe-selftest` ``conf/`` directory but not ``Y=$BUILDDIR/../bitbake/`` which
|
|
still point to the ``bitbake/`` directory)
|
|
|
|
For example (taken from :yocto_ab:`autobuilder <>` environment):
|
|
:term:`BB_LOGCONFIG` is set as:
|
|
``BB_LOGCONFIG="${BUILDDIR}/../bitbake/contrib/autobuilderlog.json"``.
|
|
Note the relative path starting from the build directory to outside of it.
|
|
This path is not changed by `oe-selftest` anymore.
|
|
|
|
Environment variables containing relative paths from tested build directory
|
|
to outside of the original build directory may need to be updated as they
|
|
won't be changed by `oe-selftest`.
