Hi Francesco,

Playing with RDEPENDS variable i'm facing the needs to
specify a dependency based on specific version of a package

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?
This should work, in fact we use it (with =) in conjunction with EXTENDPKGV
when we want to force packages from the same recipe to upgrade in lock-step.
The format for RDEPENDS is slightly different from all three.
dep (= ver)
dep (< ver)
dep (> ver)
dep (<= ver)
dep (>= ver)
(For those familiar with deb style, >> and << is not supported by the oe-core
dependency set. This is to avoid confusion as > and < are a lot more obvious.)
The items above are then mapped into their respective format depending on the
package manager you have selected.
Note: The version dependency items are not evaluated by bitbake, it only pays
attention to the package name when determining build dependencies. You would
also need to specify (in your distribution or local .conf file) a
PREFERRED_VERSION_dep = "ver" to ensure the right version is built.

Have you tried adding these specifications to an RDEPENDS value?
Cheers,
Paul
