Hi there,
Whilst working on Poky/OpenEmbedded I found the need to list all of the hard
dependencies of an RPM package within a shell script. Unfortunately --requires
or the REQUIRES tag seem to also include "soft" dependencies (i.e.
"suggests") which is not really what I need. FYI we're using RPM 5.4.0.
After a little digging I found REQUIREFLAGS, here's an example listing from
our system:
-------------------- snip --------------------

-------------------- snip --------------------
These values are not ideal for filtering via a shell script and I don't know
what the values mean. Mark Hatle pointed me to its fflags modifier which does
appear to translate some of the flags but not for the suggests (e.g.
connman-plugin-* above), here's what it says for the same package:

-------------------- snip --------------------
Any suggestions? Would we need to look at patching RPM to implement better
expansion of the flags? If so, are these flags documented anywhere or is the
source the only reference?
(Clearly some of this might be related to our specific configuration of RPM
within Poky/OE, in which case I'll defer to Mark for further elaboration on
that if needed.)
Thanks,
Paul
