For more details on the -source archiver, see the -":ref:`dev-manual/common-tasks:maintaining open source license compliance during your product's lifecycle`" -section in the Yocto Project Development Tasks Manual. - -.. _migration-1.6-packaging-changes: - -Packaging Changes ------------------ - -The following packaging changes have been made: - -- The ``binutils`` recipe no longer produces a ``binutils-symlinks`` - package. ``update-alternatives`` is now used to handle the preferred - ``binutils`` variant on the target instead. - -- The tc (traffic control) utilities have been split out of the main - ``iproute2`` package and put into the ``iproute2-tc`` package. - -- The ``gtk-engines`` schemas have been moved to a dedicated - ``gtk-engines-schemas`` package. - -- The ``armv7a`` with thumb package architecture suffix has changed. - The suffix for these packages with the thumb optimization enabled is - "t2" as it should be. Use of this suffix was not the case in the 1.5 - release. Architecture names will change within package feeds as a - result. - -.. _migration-1.6-bitbake: - -BitBake -------- - -The following changes have been made to :term:`BitBake`. - -.. _migration-1.6-matching-branch-requirement-for-git-fetching: - -Matching Branch Requirement for Git Fetching -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -When fetching source from a Git repository using -:term:`SRC_URI`, BitBake will now validate the -:term:`SRCREV` value against the branch. You can specify -the branch using the following form:: - - SRC_URI = "git://server.name/repository;branch=branchname" - -If you do not specify a branch, BitBake looks in the default "master" branch. - -Alternatively, if you need to bypass this check (e.g. if you are -fetching a revision corresponding to a tag that is not on any branch), -you can add ";nobranch=1" to the end of the URL within ``SRC_URI``. - -.. _migration-1.6-bitbake-deps: - -Python Definition substitutions -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -BitBake had some previously deprecated Python definitions within its -``bb`` module removed. You should use their sub-module counterparts -instead: - -- ``bb.MalformedUrl``: Use ``bb.fetch.MalformedUrl``. - -- ``bb.encodeurl``: Use ``bb.fetch.encodeurl``. - -- ``bb.decodeurl``: Use ``bb.fetch.decodeurl`` - -- ``bb.mkdirhier``: Use ``bb.utils.mkdirhier``. - -- ``bb.movefile``: Use ``bb.utils.movefile``. - -- ``bb.copyfile``: Use ``bb.utils.copyfile``. - -- ``bb.which``: Use ``bb.utils.which``. - -- ``bb.vercmp_string``: Use ``bb.utils.vercmp_string``. - -- ``bb.vercmp``: Use ``bb.utils.vercmp``. - -.. _migration-1.6-bitbake-fetcher: - -SVK Fetcher -~~~~~~~~~~~ - -The SVK fetcher has been removed from BitBake. - -.. _migration-1.6-bitbake-console-output: - -Console Output Error Redirection -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The BitBake console UI will now output errors to ``stderr`` instead of -``stdout``. Consequently, if you are piping or redirecting the output of -``bitbake`` to somewhere else, and you wish to retain the errors, you -will need to add ``2>&1`` (or something similar) to the end of your -``bitbake`` command line. - -.. _migration-1.6-task-taskname-overrides: - -``task-``\ taskname Overrides -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -``task-``\ taskname overrides have been adjusted so that tasks whose -names contain underscores have the underscores replaced by hyphens for -the override so that they now function properly. For example, the task -override for :ref:`ref-tasks-populate_sdk` is -``task-populate-sdk``. - -.. _migration-1.6-variable-changes: - -Changes to Variables --------------------- - -The following variables have changed. For information on the -OpenEmbedded build system variables, see the ":doc:`/ref-manual/variables`" Chapter. - -.. _migration-1.6-variable-changes-TMPDIR: - -``TMPDIR`` -~~~~~~~~~~ - -:term:`TMPDIR` can no longer be on an NFS mount. NFS does -not offer full POSIX locking and inode consistency and can cause -unexpected issues if used to store ``TMPDIR``. - -The check for this occurs on startup. If ``TMPDIR`` is detected on an -NFS mount, an error occurs. - -.. _migration-1.6-variable-changes-PRINC: - -``PRINC`` -~~~~~~~~~ - -The ``PRINC`` variable has been deprecated and triggers a warning if -detected during a build. For :term:`PR` increments on changes, -use the PR service instead. You can find out more about this service in -the ":ref:`dev-manual/common-tasks:working with a pr service`" -section in the Yocto Project Development Tasks Manual. - -.. _migration-1.6-variable-changes-IMAGE_TYPES: - -``IMAGE_TYPES`` -~~~~~~~~~~~~~~~ - -The "sum.jffs2" option for :term:`IMAGE_TYPES` has -been replaced by the "jffs2.sum" option, which fits the processing -order. - -.. _migration-1.6-variable-changes-COPY_LIC_MANIFEST: - -``COPY_LIC_MANIFEST`` -~~~~~~~~~~~~~~~~~~~~~ - -The :term:`COPY_LIC_MANIFEST` variable must now -be set to "1" rather than any value in order to enable it. - -.. _migration-1.6-variable-changes-COPY_LIC_DIRS: - -``COPY_LIC_DIRS`` -~~~~~~~~~~~~~~~~~ - -The :term:`COPY_LIC_DIRS` variable must now be set -to "1" rather than any value in order to enable it. - -.. _migration-1.6-variable-changes-PACKAGE_GROUP: - -``PACKAGE_GROUP`` -~~~~~~~~~~~~~~~~~ - -The ``PACKAGE_GROUP`` variable has been renamed to -:term:`FEATURE_PACKAGES` to more accurately -reflect its purpose. You can still use ``PACKAGE_GROUP`` but the -OpenEmbedded build system produces a warning message when it encounters -the variable. - -.. _migration-1.6-variable-changes-variable-entry-behavior: - -Preprocess and Post Process Command Variable Behavior -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The following variables now expect a semicolon separated list of -functions to call and not arbitrary shell commands: - - - :term:`ROOTFS_PREPROCESS_COMMAND` - - :term:`ROOTFS_POSTPROCESS_COMMAND` - - :term:`SDK_POSTPROCESS_COMMAND` - - :term:`POPULATE_SDK_POST_TARGET_COMMAND` - - :term:`POPULATE_SDK_POST_HOST_COMMAND` - - :term:`IMAGE_POSTPROCESS_COMMAND` - - :term:`IMAGE_PREPROCESS_COMMAND` - - :term:`ROOTFS_POSTUNINSTALL_COMMAND` - - :term:`ROOTFS_POSTINSTALL_COMMAND` - -For -migration purposes, you can simply wrap shell commands in a shell -function and then call the function. Here is an example:: - - my_postprocess_function() { - echo "hello" > ${IMAGE_ROOTFS}/hello.txt - } - ROOTFS_POSTPROCESS_COMMAND += "my_postprocess_function; " - -.. _migration-1.6-package-test-ptest: - -Package Test (ptest) --------------------- - -Package Tests (ptest) are built but not installed by default. For -information on using Package Tests, see the -":ref:`dev-manual/common-tasks:testing packages with ptest`" -section in the Yocto Project Development Tasks Manual. For information on the -``ptest`` class, see the ":ref:`ptest.bbclass <ref-classes-ptest>`" -section. - -.. _migration-1.6-build-changes: - -Build Changes -------------- - -Separate build and source directories have been enabled by default for -selected recipes where it is known to work (a whitelist) and for all -recipes that inherit the :ref:`cmake <ref-classes-cmake>` class. In -future releases the :ref:`autotools <ref-classes-autotools>` class -will enable a separate build directory by default as well. Recipes -building Autotools-based software that fails to build with a separate -build directory should be changed to inherit from the -:ref:`autotools-brokensep <ref-classes-autotools>` class instead of -the ``autotools`` or ``autotools_stage``\ classes. - -.. _migration-1.6-building-qemu-native: - -``qemu-native`` ---------------- - -``qemu-native`` now builds without SDL-based graphical output support by -default. The following additional lines are needed in your -``local.conf`` to enable it:: - - PACKAGECONFIG_pn-qemu-native = "sdl" - ASSUME_PROVIDED += "libsdl-native" - -.. note:: - - The default ``local.conf`` contains these statements. Consequently, if you - are building a headless system and using a default ``local.conf`` - file, you will need comment these two lines out. - -.. _migration-1.6-core-image-basic: - -``core-image-basic`` --------------------- - -``core-image-basic`` has been renamed to ``core-image-full-cmdline``. - -In addition to ``core-image-basic`` being renamed, -``packagegroup-core-basic`` has been renamed to -``packagegroup-core-full-cmdline`` to match. - -.. _migration-1.6-licensing: - -Licensing ---------- - -The top-level ``LICENSE`` file has been changed to better describe the -license of the various components of :term:`OpenEmbedded-Core (OE-Core)`. However, -the licensing itself remains unchanged. - -Normally, this change would not cause any side-effects. However, some -recipes point to this file within -:term:`LIC_FILES_CHKSUM` (as -``${COREBASE}/LICENSE``) and thus the accompanying checksum must be -changed from 3f40d7994397109285ec7b81fdeb3b58 to -4d92cd373abda3937c2bc47fbc49d690. A better alternative is to have -``LIC_FILES_CHKSUM`` point to a file describing the license that is -distributed with the source that the recipe is building, if possible, -rather than pointing to ``${COREBASE}/LICENSE``. - -.. _migration-1.6-cflags-options: - -``CFLAGS`` Options ------------------- - -The "-fpermissive" option has been removed from the default -:term:`CFLAGS` value. You need to take action on -individual recipes that fail when building with this option. You need to -either patch the recipes to fix the issues reported by the compiler, or -you need to add "-fpermissive" to ``CFLAGS`` in the recipes. - -.. _migration-1.6-custom-images: - -Custom Image Output Types -------------------------- - -Custom image output types, as selected using -:term:`IMAGE_FSTYPES`, must declare their -dependencies on other image types (if any) using a new -:term:`IMAGE_TYPEDEP` variable. - -.. _migration-1.6-do-package-write-task: - -Tasks ------ - -The ``do_package_write`` task has been removed. The task is no longer -needed. - -.. _migration-1.6-update-alternatives-provider: - -``update-alternative`` Provider -------------------------------- - -The default ``update-alternatives`` provider has been changed from -``opkg`` to ``opkg-utils``. This change resolves some troublesome -circular dependencies. The runtime package has also been renamed from -``update-alternatives-cworth`` to ``update-alternatives-opkg``. - -.. _migration-1.6-virtclass-overrides: - -``virtclass`` Overrides ------------------------ - -The ``virtclass`` overrides are now deprecated. Use the equivalent class -overrides instead (e.g. ``virtclass-native`` becomes ``class-native``.) - -.. _migration-1.6-removed-renamed-recipes: - -Removed and Renamed Recipes ---------------------------- - -The following recipes have been removed: - -- ``packagegroup-toolset-native`` - This recipe is largely unused. - -- ``linux-yocto-3.8`` - Support for the Linux yocto 3.8 kernel has been - dropped. Support for the 3.10 and 3.14 kernels have been added with - the ``linux-yocto-3.10`` and ``linux-yocto-3.14`` recipes. - -- ``ocf-linux`` - This recipe has been functionally replaced using - ``cryptodev-linux``. - -- ``genext2fs`` - ``genext2fs`` is no longer used by the build system - and is unmaintained upstream. - -- ``js`` - This provided an ancient version of Mozilla's javascript - engine that is no longer needed. - -- ``zaurusd`` - The recipe has been moved to the ``meta-handheld`` - layer. - -- ``eglibc 2.17`` - Replaced by the ``eglibc 2.19`` recipe. - -- ``gcc 4.7.2`` - Replaced by the now stable ``gcc 4.8.2``. - -- ``external-sourcery-toolchain`` - this recipe is now maintained in - the ``meta-sourcery`` layer. - -- ``linux-libc-headers-yocto 3.4+git`` - Now using version 3.10 of the - ``linux-libc-headers`` by default. - -- ``meta-toolchain-gmae`` - This recipe is obsolete. - -- ``packagegroup-core-sdk-gmae`` - This recipe is obsolete. - -- ``packagegroup-core-standalone-gmae-sdk-target`` - This recipe is - obsolete. - -.. _migration-1.6-removed-classes: - -Removed Classes ---------------- - -The following classes have become obsolete and have been removed: - -- ``module_strip`` - -- ``pkg_metainfo`` - -- ``pkg_distribute`` - -- ``image-empty`` - -.. _migration-1.6-reference-bsps: - -Reference Board Support Packages (BSPs) ---------------------------------------- - -The following reference BSPs changes occurred: - -- The BeagleBoard (``beagleboard``) ARM reference hardware has been - replaced by the BeagleBone (``beaglebone``) hardware. - -- The RouterStation Pro (``routerstationpro``) MIPS reference hardware - has been replaced by the EdgeRouter Lite (``edgerouter``) hardware. - -The previous reference BSPs for the ``beagleboard`` and -``routerstationpro`` machines are still available in a new -``meta-yocto-bsp-old`` layer in the -:yocto_git:`Source Repositories <>` at -:yocto_git:`/meta-yocto-bsp-old/`. - - |
