thanks for reply, i original method was specified the package version in
local.conf by PREFEREED_VERSION.
i wondering if configure package version in package group via RDEPENDS makes it
possible? but it seems impossible.
what situations allow REDPENDS to specify a version? thanks.
As far as I remember, RDEPENDS is handled by the package manager when
installing the package. So I imagine this is a way to make sure that a
filesystem is not built with two packages that are incompatible at
runtime by failing when creating the filesystem. The choice of which
version to build is a responsibility of Bitbake which happens way before
RDEPENDS.
Also, chant #1 of Yocto applies:
recipe data is local, config data is global.
So you cannot impact one recipe from another, this implies you cannot
pick a version of one recipe from another, you can only say whether
you're compatible with it.
Cheers,
Quentin
