This seems to imply that these options have some basic level of functionality even when the corresponding shared library isn't found at runtime. Is that right? If there's no functionality at all without the corresponding shared library then these should just be regular dependencies (and users who need smaller images should disable via the PACKAGECONFIG rather than leaving the PACKAGECONFIG enabled but then excluding the shared library). Note also that PACKAGECONFIG gives a way to express recommended dependencies (the 5th argument). https://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#var-PACKAGECONFIG > Signed-off-by: Luca Boccassi <luca.bocca...@microsoft.com> > --- > meta/recipes-core/systemd/systemd_247.1.bb | 7 +++++++ > 1 file changed, 7 insertions(+) > > diff --git a/meta/recipes-core/systemd/systemd_247.1.bb > b/meta/recipes-core/systemd/systemd_247.1.bb > index f20e86d94b..951bffa23f 100644 > --- a/meta/recipes-core/systemd/systemd_247.1.bb > +++ b/meta/recipes-core/systemd/systemd_247.1.bb > @@ -603,6 +603,13 @@ RRECOMMENDS_${PN} += "systemd-extra-utils \ > systemd-conf \ > " > > +# Weak dlopen-style dependencies: if explicitly requested via PACKAGECONFIG, > recommend them > +RRECOMMENDS_${PN} += "${@bb.utils.contains('PACKAGECONFIG', 'qrencode', > 'qrencode', '', d)} \ > + ${@bb.utils.contains('PACKAGECONFIG', 'libidn', > 'libidn', '', d)} \ > + ${@bb.utils.contains('PACKAGECONFIG', 'libidn2', > 'libidn2', '', d)} \ > + ${@bb.utils.contains('PACKAGECONFIG', 'cryptsetup', > 'cryptsetup', '', d)} \ > +" > + > INSANE_SKIP_${PN} += "dev-so libdir" > INSANE_SKIP_${PN}-dbg += "libdir" > INSANE_SKIP_${PN}-doc += " libdir" > -- > 2.29.2 > > > >
