linux/poky.git/meta/classes-recipe/toolchain-scripts.bbclass, branch master

The poky repository master branch is no longer being updated.

2025-11-07T13:31:53+00:00

You can either: a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs b) use the new bitbake-setup You can find information about either approach in our documentation: https://docs.yoctoproject.org/ Note that "poky" the distro setting is still available in meta-yocto as before and we continue to use and maintain that. Long live Poky! Some further information on the background of this change can be found in: https://lists.openembedded.org/g/openembedded-architecture/message/2179 Signed-off-by: Richard Purdie

meta/classes-recipe/toolchain-scripts.bbclass: eliminate bash-ism

2025-10-09T09:58:07+00:00

Sourcing a script with arguments is a non-standard bash extension and doesn't work with other shells (e.g. dash, which is used on Debian and derivatives). This used to work by coincidence when running against integrated poky repo without having to separately specify where bitbake is, but no longer does. Using set is a POSIX standard.

toolchain-scripts.bbclass: fix bitbake-setup compatibility

2025-10-09T09:58:07+00:00

Pass the BITBAKEDIR parameter to oe-init-build-env when called from the environment-setup script. This fixes compatibility with bitbake-setup, which places bitbake in a different directory structure than the standard poky repository layout where bitbake is located alongside oe-init-build-env. The issue was discovered when running the oe-selftest test DevtoolIdeSdkTests.test_devtool_ide_sdk_shared_sysroots, which failed because the environment-setup script was not able to find bitbake.

classes/lib: Switch classextend to use new filter API

2025-08-12T09:05:11+00:00

Currently, class extensions are implmented using shadow variables and access indirection which is horribly ineffient and ugly. Switch to using the new bitbake filter API, which allows a translation of the variable before the expanded value is returned. This allows us to drop the shadow variable accesses. It also avoids the need to iterate PACKAGES and make many variable changes since a filter against RDEPENDS applies to RDEPENDS:${PN} and all of it's other overridden values. Since data expansion happens at access, it also avoids many of the race conditions this code has tranditionally been plagued with.

toolchain-scripts: Export meson settings for SDK builds

2025-05-12T21:01:55+00:00

Create a new set of exports for the Meson `host_machine` cross settings. This allows the target cross file to be created correctly from meson.cross.template and aligns with meson.bbclass. Note, one might think that HOST_OS and HOST_ARCH would be appropriate as inputs here, aligning nicely with the Meson naming. That turns out to be incorrect since the script is generated in a native/nativesdk build with HOST_OS and HOST_ARCH set for the "build machine", not the "host machine", using the Meson terminology. See https://mesonbuild.com/Cross-compilation.html.

toolchain-scripts: Add Meson settings for Yocto build SDK

2025-05-12T21:01:55+00:00

The Meson settings for the standalone SDK also need to be available for the Yocto build SDK, a.k.a. meta-ide-support. (From OE-Core rev: 6287114bf10718fe49f7c1ed211f3d99f0933bc4) (From OE-Core rev: d69d049e9a7114323a1e1b8da4999e9e3f08ad03) Signed-off-by: Tom Hochstein Signed-off-by: Richard Purdie

siteconfig: Drop siteconfig class/code/support

2024-05-31T15:58:36+00:00

The siteconfig code was only used for 5 cache values. The complexity added to sstate to support this code was considerable and the runtime much more significant than any benefit the cache files would have added. Drop the support for this which was only used minimally for ncurses and zlib. (From OE-Core rev: f3766dc038f7ba9780ddaf5eb8d27385ea31d7d0) Signed-off-by: Richard Purdie

toolchain-scripts: export the target endianism and word size

2024-05-22T09:21:26+00:00

Some build systems (notably, Meson) like to be told when cross-compiling what the target endian and word size is. We don't have these exported via the variables, so add them using siteinfo as a source of data.

toolchain-scripts: Handle spaces within user $PATH

2023-03-11T00:08:41+00:00

The environment-setup script generated by the recipe was not quoting the user existing PATH when updating it causing the export command to fail. Add necessary double quotes around $PATH.
