I would perhaps suggest looking at pkgdata -  bitbake -e foo | grep PKGDATA_DIR  and then look in runtime/foo under that and see what RDEPENDS is indicated in there.

Thanks for the hint. All I can say is that it looks good:

RDEPENDS_foo: libstdc++ (>= 6.3.0) glibc (>= 2.25) libcrypto (>= 1.0.2k)
jsoncpp (>= 1.8.0) libmosquitto1 (>= 1.4.10) libcurl (>= 7.53.1) libgcc
(>= 6.3.0) libssl (>= 1.0.2k)

Then, in bar

RDEPENDS_bar: foo (>= 1.4.0-git0e371231) glibc (>= 2.25) jsoncpp (>=
1.8.0) libstdc++ (>= 6.3.0) libgcc (>= 6.3.0)

(foo and bar of course replacements to protect the innocent)

Again, libmosquitto1 is missing in rootfs except if I add the package to
the image recipe.

I am using pyro, if that is of any help.

Thanks,
