I've done a bit more work on this and the more I dig, the more I think we have some issues we need to sort with taking a step back and checking some assumptions. What I'm lacking is a good way to test the resulting rust toolchain. Would someone with some rust knowledge be able to add something to meta/lib/oeqa/sdk/cases/ which tested rust in the SDK? If someone can add some rust tests in the SDK, I think I might have an idea of what the patches look like to properly fix the rust toolchain there. Cheers, Richard
