We could avoid this by using: TOOLCHAIN_NATIVE ??= "${PREFERRED_TOOLCHAIN_NATIVE}" inherit_defer toolchain/${TOOLCHAIN_NATIVE}-native and then having recipes set: TOOLCHAIN = "gcc" TOOLCHAIN_NATIVE = "gcc" I really want to avoid inheriting both gcc-native and clang-native. If we have to remove the host_gcc_version function, that is probably ok. I think it is mostly used for the uninative gcc 4.8 and 4.9 issue but I doubt we have any distro with those older gcc versions on now? Cheers, Richard

This helps build native recipe with clang as native compiler. when PREFERRED_TOOLCHAIN_NATIVE = "clang", otherwise it will inherit gcc-native, this is a bit redundant when gcc native is used, ideally we should defer_inherit it always but there is some code in classes assuming gcc as native compiler e.g. oe.utils.host_gcc_version function expects BUILD_CC early during parsing.
