Yocto build error

[jwinarske]

Moving to tip of tree I'm hitting this build error:

Thanks for the report and error log. This appears to have been a configuration edge case in serde_yaml but has been fixed in version 0.8.24. My recent changes on the main branch that could affect builds is:

1. Routine updates of several dependencies to newer patch versions (no serde packages were updated).
2. Removal of the Cargo.lock file since this project is used by other projects as a library. The lockfiles for lib projects are ignored by Cargo anyway so I wouldn't expect this to have any effect unless Yocto was somehow relying on it.

I notice one peculiarity... the version shown in the bitbake config is 0.8.24 (which has the bugfix) but the log above shows 0.8.21 in line /usr/src/debug/membrane-dart-example/git-r0/cargo_home/bitbake/serde_yaml-0.8.21/src/mapping.rs:16 which does not have the bugfix. Any idea why those should differ?

@jerel The recipe in Meta-flutter kirkstone builds fine. I ran cargo bitbake on your tip of tree, which is where I hit the issue. I was trying to pick up your recent changes before AGL roll.
