Any - instance where this is not the case, now triggers a warning. You must - either remove the continuation character, or be sure the next line is - a comment. - -- *Package Name Overrides:* The runtime package specific variables - :term:`RDEPENDS`, - :term:`RRECOMMENDS`, - :term:`RSUGGESTS`, - :term:`RPROVIDES`, - :term:`RCONFLICTS`, - :term:`RREPLACES`, :term:`FILES`, - :term:`ALLOW_EMPTY`, and the pre, post, install, - and uninstall script functions ``pkg_preinst``, ``pkg_postinst``, - ``pkg_prerm``, and ``pkg_postrm`` should always have a package name - override. For example, use ``RDEPENDS_${PN}`` for the main package - instead of ``RDEPENDS``. BitBake uses more strict checks when it - parses recipes. - -.. _migration-1.4-build-behavior: - -Build Behavior --------------- - -Differences include the following: - -- *Shared State Code:* The shared state code has been optimized to - avoid running unnecessary tasks. For example, the following no longer - populates the target sysroot since that is not necessary:: - - $ bitbake -c rootfs some-image - - Instead, the system just needs to extract the - output package contents, re-create the packages, and construct the - root filesystem. This change is unlikely to cause any problems unless - you have missing declared dependencies. - -- *Scanning Directory Names:* When scanning for files in - :term:`SRC_URI`, the build system now uses - :term:`FILESOVERRIDES` instead of - :term:`OVERRIDES` for the directory names. In - general, the values previously in ``OVERRIDES`` are now in - ``FILESOVERRIDES`` as well. However, if you relied upon an additional - value you previously added to ``OVERRIDES``, you might now need to - add it to ``FILESOVERRIDES`` unless you are already adding it through - the :term:`MACHINEOVERRIDES` or - :term:`DISTROOVERRIDES` variables, as - appropriate. For more related changes, see the - ":ref:`ref-manual/migration-1.4:variables`" section. - -.. _migration-1.4-proxies-and-fetching-source: - -Proxies and Fetching Source ---------------------------- - -A new ``oe-git-proxy`` script has been added to replace previous methods -of handling proxies and fetching source from Git. See the -``meta-yocto/conf/site.conf.sample`` file for information on how to use -this script. - -.. _migration-1.4-custom-interfaces-file-netbase-change: - -Custom Interfaces File (netbase change) ---------------------------------------- - -If you have created your own custom ``etc/network/interfaces`` file by -creating an append file for the ``netbase`` recipe, you now need to -create an append file for the ``init-ifupdown`` recipe instead, which -you can find in the :term:`Source Directory` at -``meta/recipes-core/init-ifupdown``. For information on how to use -append files, see the -":ref:`dev-manual/common-tasks:using .bbappend files in your layer`" -section in the Yocto Project Development Tasks Manual. - -.. _migration-1.4-remote-debugging: - -Remote Debugging ----------------- - -Support for remote debugging with the Eclipse IDE is now separated into -an image feature (``eclipse-debug``) that corresponds to the -``packagegroup-core-eclipse-debug`` package group. Previously, the -debugging feature was included through the ``tools-debug`` image -feature, which corresponds to the ``packagegroup-core-tools-debug`` -package group. - -.. _migration-1.4-variables: - -Variables ---------- - -The following variables have changed: - -- ``SANITY_TESTED_DISTROS``: This variable now uses a distribution - ID, which is composed of the host distributor ID followed by the - release. Previously, - :term:`SANITY_TESTED_DISTROS` was - composed of the description field. For example, "Ubuntu 12.10" - becomes "Ubuntu-12.10". You do not need to worry about this change if - you are not specifically setting this variable, or if you are - specifically setting it to "". - -- ``SRC_URI``: The ``${``\ :term:`PN`\ ``}``, - ``${``\ :term:`PF`\ ``}``, - ``${``\ :term:`P`\ ``}``, and ``FILE_DIRNAME`` directories - have been dropped from the default value of the - :term:`FILESPATH` variable, which is used as the - search path for finding files referred to in - :term:`SRC_URI`. If you have a recipe that relied upon - these directories, which would be unusual, then you will need to add - the appropriate paths within the recipe or, alternatively, rearrange - the files. The most common locations are still covered by ``${``\ :term:`BP`\ ``}``, - ``${``\ :term:`BPN`\ ``}``, and "files", which all remain in the default value of - :term:`FILESPATH`. - -.. _migration-target-package-management-with-rpm: - -Target Package Management with RPM ----------------------------------- - -If runtime package management is enabled and the RPM backend is -selected, Smart is now installed for package download, dependency -resolution, and upgrades instead of Zypper. For more information on how -to use Smart, run the following command on the target:: - - smart --help - -.. _migration-1.4-recipes-moved: - -Recipes Moved -------------- - -The following recipes were moved from their previous locations because -they are no longer used by anything in the OpenEmbedded-Core: - -- ``clutter-box2d``: Now resides in the ``meta-oe`` layer. - -- ``evolution-data-server``: Now resides in the ``meta-gnome`` layer. - -- ``gthumb``: Now resides in the ``meta-gnome`` layer. - -- ``gtkhtml2``: Now resides in the ``meta-oe`` layer. - -- ``gupnp``: Now resides in the ``meta-multimedia`` layer. - -- ``gypsy``: Now resides in the ``meta-oe`` layer. - -- ``libcanberra``: Now resides in the ``meta-gnome`` layer. - -- ``libgdata``: Now resides in the ``meta-gnome`` layer. - -- ``libmusicbrainz``: Now resides in the ``meta-multimedia`` layer. - -- ``metacity``: Now resides in the ``meta-gnome`` layer. - -- ``polkit``: Now resides in the ``meta-oe`` layer. - -- ``zeroconf``: Now resides in the ``meta-networking`` layer. - -.. _migration-1.4-removals-and-renames: - -Removals and Renames --------------------- - -The following list shows what has been removed or renamed: - -- ``evieext``: Removed because it has been removed from ``xserver`` - since 2008. - -- *Gtk+ DirectFB:* Removed support because upstream Gtk+ no longer - supports it as of version 2.18. - -- ``libxfontcache / xfontcacheproto``: Removed because they were - removed from the Xorg server in 2008. - -- ``libxp / libxprintapputil / libxprintutil / printproto``: Removed - because the XPrint server was removed from Xorg in 2008. - -- ``libxtrap / xtrapproto``: Removed because their functionality was - broken upstream. - -- *linux-yocto 3.0 kernel:* Removed with linux-yocto 3.8 kernel being - added. The linux-yocto 3.2 and linux-yocto 3.4 kernels remain as part - of the release. - -- ``lsbsetup``: Removed with functionality now provided by - ``lsbtest``. - -- ``matchbox-stroke``: Removed because it was never more than a - proof-of-concept. - -- ``matchbox-wm-2 / matchbox-theme-sato-2``: Removed because they are - not maintained. However, ``matchbox-wm`` and ``matchbox-theme-sato`` - are still provided. - -- ``mesa-dri``: Renamed to ``mesa``. - -- ``mesa-xlib``: Removed because it was no longer useful. - -- ``mutter``: Removed because nothing ever uses it and the recipe is - very old. - -- ``orinoco-conf``: Removed because it has become obsolete. - -- ``update-modules``: Removed because it is no longer used. The - kernel module ``postinstall`` and ``postrm`` scripts can now do the - same task without the use of this script. - -- ``web``: Removed because it is not maintained. Superseded by - ``web-webkit``. - -- ``xf86bigfontproto``: Removed because upstream it has been disabled - by default since 2007. Nothing uses ``xf86bigfontproto``. - -- ``xf86rushproto``: Removed because its dependency in ``xserver`` - was spurious and it was removed in 2005. - -- ``zypper / libzypp / sat-solver``: Removed and been functionally - replaced with Smart (``python-smartpm``) when RPM packaging is used - and package management is enabled on the target. - |
