But another approach using something like this LDCONFIG_SLIBIDR=${@bb.utils.contains('DISTRO_FEATURES', 'usrmerge', '/usr/lib', '/lib', d)} $CC ldconfig.c -std=gnu99 -DSLIBDIR=\"${LDCONFIG_SLIBIDR}\" chroot_canon.c xmalloc.c xstrdup.c cache.c readlib.c -I. dl-cache.c -o ldconfig doesn't work either because usrmerge isn't in the DISTRO_FEATURES in case of native, at least it seems so. DISTRO_FEATURES_NATIVE:append = " usrmerge" fixes this but I have no idea if this is the right approach. > > > >> > >> > >> Thanks, > >> Hannes
