[yocto] Package specific version dependencies

[Francesco Del Degan]

Hi all,

Playing with RDEPENDS variable i'm facing the needs to
specify a dependency based on specific version of a package
(greather than, in my specific case).

The underlying package managers supports declaring dependencies
including version relationships, for example:

Rpm:  Requires: package_xxx >= 1.0.27
Deb:  Depends: libc6 (>= 2.2.1)
Okpg: Depends: xfree (>= 6.0), glib2

Is this feature just missing in yocto or it's explicitly denied
for some reason?

In first case:
Could a patch (I will need to work on package*.bbclass i guess)
be useful for Yocto/OE?

What could be a good syntax for bitbake variable in order to specify
this?

Thanks,
  Francesco 'pr0gg3d' Del Degan
