linux/poky.git/meta/classes-recipe/cargo_common.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The poky repository master branch is no longer being updated.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

classes/cargo_common: ensure B is clean

2025-10-27T11:37:42+00:00

The cargo class defaults to out-of-tree builds in WORKDIR/build, but at no point was that directory cleaned. This causes problems with the rust standard library recipe (libstd-rs) which installs manually with cp, so rebuilds can be contaminated with the contents of previous builds. I believe that post-release we should switch cargo.bbclass to mandating out-of-tree builds to reduce the complexity, but for now in out-of-tree builds we can just delete the ${B}/target directory. Note that we use ${B}/target because there at least were reasons to use that name[1], it is unclear if these limitations still hold. We can't simply clean ${B} because that will break recipes that use cargo and something else to build, for example librsvg.

cargo_common: use 'config.toml' instead of plain 'config'

2025-02-25T12:17:22+00:00

cargo configuration has been renamed from plain 'config' to 'config.toml' in rust-1.38. Using the old name is still supported but creates warnings like | $ cargo | warning: `/sdk.../home/cargo/config` is deprecated in favor of `config.toml` | note: if you need to support cargo 1.38 or earlier, you can symlink `config` to `config.toml` Use the new name.

cargo_common.bbclass: Support git repos with submodules

2024-08-08T13:28:49+00:00

This is useful for cargo dependencies specified as git repositories, where those repositories themselves have submodules that need to be checked out.

cargo: remove True option to getVar calls

2024-06-27T12:03:34+00:00

recipes: Start WORKDIR -> UNPACKDIR transition

2024-05-21T11:08:04+00:00

Replace references of WORKDIR with UNPACKDIR where it makes sense to do so in preparation for changing the default value of UNPACKDIR. (From OE-Core rev: 1f18b9a512800860d5153d89eb82b56388efad6f) Signed-off-by: Richard Purdie

cargo: Add CARGO_LOCK_PATH for path to Cargo.lock

2023-12-09T19:17:11+00:00

When building a workspace enabled project, the Cargo.lock is found at the root of the project, not alongside the Cargo.toml. Expose CARGO_LOCK_PATH so it can be explicitly configured.

rust: cargo: Convert single-valued variables to weak defaults

2023-12-09T19:17:11+00:00

All of these variables are single-valued, so we can use weak-defaults for them and only see the final assignment after parsing. (From OE-Core rev: 3221e82a35a149fdf38fe66dcd5de758ac1b9185) Signed-off-by: Alex Kiernan Signed-off-by: Richard Purdie

cargo: Move CARGO_MANIFEST_PATH/CARGO_SRC_DIR to cargo_common

2023-12-09T19:17:11+00:00

cargo_common_do_configure uses CARGO_MANIFEST_PATH (which depends on CARGO_SRC_DIR), but their definition was in cargo.bbclass. (From OE-Core rev: 740374a13ad5359767b421666decf50c158ea0df) Signed-off-by: Alex Kiernan Signed-off-by: Richard Purdie

cargo: Rename MANIFEST_PATH -> CARGO_MANIFEST_PATH

2023-12-08T16:58:34+00:00

This variable is a piece of recipe configurable interface, scope it with the class name to make that clear. (From OE-Core rev: 0101de25832fbed3d08cd522512784133c628cad) Signed-off-by: Alex Kiernan Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie
