Release 2.7 (warrior)
|
||||
=====================
|
||||
|
||||
This section provides migration information for moving to the Yocto
|
||||
Project 2.7 Release (codename "warrior") from the prior release.
|
||||
|
||||
.. _migration-2.7-bitbake-changes:
|
||||
|
||||
BitBake Changes
|
||||
---------------
|
||||
|
||||
The following changes have been made to BitBake:
|
||||
|
||||
- BitBake now checks anonymous Python functions and pure Python
|
||||
functions (e.g. ``def funcname:``) in the metadata for tab
|
||||
indentation. If found, BitBake produces a warning.
|
||||
|
||||
- BitBake now checks
|
||||
:term:`BBFILE_COLLECTIONS` for duplicate
|
||||
entries and triggers an error if any are found.
|
||||
|
||||
.. _migration-2.7-eclipse-support-dropped:
|
||||
|
||||
Eclipse Support Removed
|
||||
-----------------------
|
||||
|
||||
Support for the Eclipse IDE has been removed. Support continues for
|
||||
those releases prior to 2.7 that did include support. The 2.7 release
|
||||
does not include the Eclipse Yocto plugin.
|
||||
|
||||
.. _migration-2.7-qemu-native-splits-system-and-user-mode-parts:
|
||||
|
||||
``qemu-native`` Splits the System and User-Mode Parts
|
||||
-----------------------------------------------------
|
||||
|
||||
The system and user-mode parts of ``qemu-native`` are now split.
|
||||
``qemu-native`` provides the user-mode components and
|
||||
``qemu-system-native`` provides the system components. If you have
|
||||
recipes that depend on QEMU's system emulation functionality at build
|
||||
time, they should now depend upon ``qemu-system-native`` instead of
|
||||
``qemu-native``.
|
||||
|
||||
.. _migration-2.7-upstream-tracking.inc-removed:
|
||||
|
||||
The ``upstream-tracking.inc`` File Has Been Removed
|
||||
---------------------------------------------------
|
||||
|
||||
The previously deprecated ``upstream-tracking.inc`` file is now removed.
|
||||
Any ``UPSTREAM_TRACKING*`` variables are now set in the corresponding
|
||||
recipes instead.
|
||||
|
||||
Remove any references you have to the ``upstream-tracking.inc`` file in
|
||||
your configuration.
|
||||
|
||||
.. _migration-2.7-distro-features-libc-removed:
|
||||
|
||||
The ``DISTRO_FEATURES_LIBC`` Variable Has Been Removed
|
||||
------------------------------------------------------
|
||||
|
||||
The ``DISTRO_FEATURES_LIBC`` variable is no longer used. The ability to
|
||||
configure glibc using kconfig has been removed for quite some time
|
||||
making the ``libc-*`` features set no longer effective.
|
||||
|
||||
Remove any references you have to ``DISTRO_FEATURES_LIBC`` in your own
|
||||
layers.
|
||||
|
||||
.. _migration-2.7-license-values:
|
||||
|
||||
License Value Corrections
|
||||
-------------------------
|
||||
|
||||
The following corrections have been made to the
|
||||
:term:`LICENSE` values set by recipes:
|
||||
|
||||
- *socat*: Corrected :term:`LICENSE` to be "GPLv2" rather than "GPLv2+".
|
||||
- *libgfortran*: Set license to "GPL-3.0-with-GCC-exception".
|
||||
- *elfutils*: Removed "Elfutils-Exception" and set to "GPLv2" for shared libraries
|
||||
|
||||
.. _migration-2.7-packaging-changes:
|
||||
|
||||
Packaging Changes
|
||||
-----------------
|
||||
|
||||
This section provides information about packaging changes.
|
||||
|
||||
- ``bind``: The ``nsupdate`` binary has been moved to the
|
||||
``bind-utils`` package.
|
||||
|
||||
- Debug split: The default debug split has been changed to create
|
||||
separate source packages (i.e. ``package_name-dbg`` and
|
||||
``package_name-src``). If you are currently using ``dbg-pkgs`` in
|
||||
:term:`IMAGE_FEATURES` to bring in debug
|
||||
symbols and you still need the sources, you must now also add
|
||||
``src-pkgs`` to :term:`IMAGE_FEATURES`. Source packages remain in the
|
||||
target portion of the SDK by default, unless you have set your own
|
||||
value for :term:`SDKIMAGE_FEATURES` that
|
||||
does not include ``src-pkgs``.
|
||||
|
||||
- Mount all using ``util-linux``: ``/etc/default/mountall`` has moved
|
||||
into the -mount sub-package.
|
||||
|
||||
- Splitting binaries using ``util-linux``: ``util-linux`` now splits
|
||||
each binary into its own package for fine-grained control. The main
|
||||
``util-linux`` package pulls in the individual binary packages using
|
||||
the :term:`RRECOMMENDS` and
|
||||
:term:`RDEPENDS` variables. As a result, existing
|
||||
images should not see any changes assuming
|
||||
:term:`NO_RECOMMENDATIONS` is not set.
|
||||
|
||||
- ``netbase/base-files``: ``/etc/hosts`` has moved from ``netbase`` to
|
||||
``base-files``.
|
||||
|
||||
- ``tzdata``: The main package has been converted to an empty meta
|
||||
package that pulls in all ``tzdata`` packages by default.
|
||||
|
||||
- ``lrzsz``: This package has been removed from
|
||||
``packagegroup-self-hosted`` and
|
||||
``packagegroup-core-tools-testapps``. The X/Y/ZModem support is less
|
||||
likely to be needed on modern systems. If you are relying on these
|
||||
packagegroups to include the ``lrzsz`` package in your image, you now
|
||||
need to explicitly add the package.
|
||||
|
||||
.. _migration-2.7-removed-recipes:
|
||||
|
||||
Removed Recipes
|
||||
---------------
|
||||
|
||||
The following recipes have been removed:
|
||||
|
||||
- *gcc*: Drop version 7.3 recipes. Version 8.3 now remains.
|
||||
- *linux-yocto*: Drop versions 4.14 and 4.18 recipes. Versions 4.19 and 5.0 remain.
|
||||
- *go*: Drop version 1.9 recipes. Versions 1.11 and 1.12 remain.
|
||||
- *xvideo-tests*: Became obsolete.
|
||||
- *libart-lgpl*: Became obsolete.
|
||||
- *gtk-icon-utils-native*: These tools are now provided by gtk+3-native
|
||||
- *gcc-cross-initial*: No longer needed. gcc-cross/gcc-crosssdk is now used instead.
|
||||
- *gcc-crosssdk-initial*: No longer needed. gcc-cross/gcc-crosssdk is now used instead.
|
||||
- *glibc-initial*: Removed because the benefits of having it for site_config are currently outweighed by the cost of building the recipe.
|
||||
|
||||
.. _migration-2.7-removed-classes:
|
||||
|
||||
Removed Classes
|
||||
---------------
|
||||
|
||||
The following classes have been removed:
|
||||
|
||||
- *distutils-tools*: This class was never used.
|
||||
- *bugzilla.bbclass*: Became obsolete.
|
||||
- *distrodata*: This functionally has been replaced by a more modern tinfoil-based implementation.
|
||||
|
||||
.. _migration-2.7-miscellaneous-changes:
|
||||
|
||||
Miscellaneous Changes
|
||||
---------------------
|
||||
|
||||
The following miscellaneous changes occurred:
|
||||
|
||||
- The ``distro`` subdirectory of the Poky repository has been removed
|
||||
from the top-level ``scripts`` directory.
|
||||
|
||||
- Perl now builds for the target using
|
||||
`perl-cross <https://arsv.github.io/perl-cross/>`_ for better
|
||||
maintainability and improved build performance. This change should
|
||||
not present any problems unless you have heavily customized your Perl
|
||||
recipe.
|
||||
|
||||
- ``arm-tunes``: Removed the "-march" option if mcpu is already added.
|
||||
|
||||
- ``update-alternatives``: Convert file renames to
|
||||
:term:`PACKAGE_PREPROCESS_FUNCS`
|
||||
|
||||
- ``base/pixbufcache``: Obsolete ``sstatecompletions`` code has been
|
||||
removed.
|
||||
|
||||
- :ref:`ref-classes-native` class: :term:`RDEPENDS` handling has been enabled.
|
||||
|
||||
- ``inetutils``: This recipe has rsh disabled.
