Right, this is the error: | In file included from /srv/storage/alex/yocto/build-multilib/tmp/work/x86_64-pokymllib64-linux/lib64-mg/20230501/lib64-recipe-sysroot/usr/include/bsd/sys/cdefs.h:27, | from /srv/storage/alex/yocto/build-multilib/tmp/work/x86_64-pokymllib64-linux/lib64-mg/20230501/lib64-recipe-sysroot/usr/include/bsd/sys/queue.h:39, | from region.c:12: | /srv/storage/alex/yocto/build-multilib/tmp/work/x86_64-pokymllib64-linux/lib64-mg/20230501/lib64-recipe-sysroot/usr/include/bsd/sys/cdefs-64.h:49:24: error: no include path in which to search for sys/cdefs.h | 49 | #if __has_include_next(<sys/cdefs.h>) | | ^~~~~~~~~~~~~ I'm utterly confused by that. Why can't the compiler find usr/include/sys/cdefs.h? Why is it then happily finding it when bsd/ prefix is dropped from cdefs-64 include statement in usr/include/bsd/sys/cdefs.h ? But the fix does seem to help, and makes multilib selection header match libbsd headers (in overlay mode). So: - the patch is ok; but please add a note (a comment in the recipe just above sed) that it hasn't been tested when libbsd is used in 'namespaced headers' mode according to https://man.archlinux.org/man/libbsd.7 Alex
