This commit changed the target generation keyed of from just <arch> to <arch>-<abi>: https://git.openembedded.org/openembedded-core/commit/?id=79bd6389585327820dfc1a1d29f60779ef08b2e0 These are the commits that changed the entry back and forth between "arm" and "arm-eabi": https://git.openembedded.org/openembedded-core/commit/?id=ef49f89c89889466ee3696ab680f8e10c961a677 https://git.openembedded.org/openembedded-core/commit/?id=299f429a1ee387681ba70e33ca23f165e5837961 https://git.openembedded.org/openembedded-core/commit/?id=a4886f02dfb78e861fd7afe07b4a25c262bf0421 Since qemuarm = armv7, not sure why "arm" entry was modified, not "armv7". This does affect qemuarmv5 negatively though. 95579 3 randy.macleod 2023-05-20 18:59:21 +0000 I think I heard Steve say that this likely won't get fixed on the 4.0.* branch. Since we have The newer rust code and build rules in: https://git.yoctoproject.org/meta-lts-mixins/log/?h=kirkstone/rust-1.68 I'm going to close the defect as Won't Fix. If that's a problem for you Denys, please re-open and explain why you can't use the mixin layer.
