What is the difference between packages qemu and qemu-native in Yocto?

I would like to understand the relationship between the two packages because it seems that changing the source uri for 'qemu' causes build breakage for qemu-native.

I am not a Yocot/Bitbake expert, so a bit of clarification would go a long way.

Thanks.

Solution

  • -native just indicates it is a package built for the native platform (to be run in the native sysroot on the build host), and not for the cross-compiled target platform. qemu and qemu-native are both built from the same recipe: that's why changing SRC_URI affects both. The -native version is there because somewhere in the recipe it says

    BBCLASSEXTEND = "native"
