Hi. We are using a 3.6 based kernel in our builds using a custom kernel recipe. However, I can see that the linux-libc-headers built but based on a 3.8 kernel? Is this really how it should be? Are we supposed to also make a custom recipe for the linux-libc-headers? The image seems to be executing fine but I am a bit worried about the version mismatch :(
You shouldn't need to do this. We use a single libc-headers version for all of a given linux-yocto kernels in a release. The userspace / libc ABI is stable, and backwards compatible (generally speaking of course). New interfaces typically have a fallback if the kernel interface is missing, and we don't currently have any issues either. Of course older headers with newer kernels is even safer, since typically at most you are missing out on being able to use new APIs versus potential for missing APIs. Summary: you can match them if you want, but we are testing across several kernel versions and haven't found any issues (yet). Cheers, Bruce
Hans PS. I believe I posted this question before but I am no longer 100% convinced it actually left my outbox. At least I never got a response, which usually happens very quickly :) _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
