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

I think your major concern is “I have multiple version for opencv, but bibake installed the version 3.4.3 default.”.

It’s because layers have different layer priorities specified by BBFILE_PRIORITY in layer.conf, and for recipes with the same name in different layers, the one in higher priority layer will be selected regardless of the recipes’ versions.

In such case, you can set PREFERRED_VERSION to use the one you want.

I have multiple version for opencv, but bibake installed the version 3.4.3 default.

=== Matching recipes: ===

opencv:

  meta-rcar-gen3-adas  3.4.3+gitAUTOINC+b38c50b3d0_1f6d6f0626_bdb7bb85f3_34e4206aef_fccf7cd6a4

  meta-oe              4.1.0

  meta-rcar-gen3-adas  2.4.11+gitAUTOINC+707d10f115

  meta-rcar-gen3-adas  3.2+gitAUTOINC+70bbf17b13

the yocto offical documents mentioned the variable RDEPENDS supports operator for specify versions.

then i specified the version to 4.1.0 for opencv in package group.

SUMMARY = "Requirement packages"

PR = "r1"

inherit packagegroup

RDEPENDS:${PN} = " \

        opencv (>= 4.1.0)\

        libopencv-core-dev \

        libopencv-highgui-dev \

        libopencv-imgproc-dev \

        libopencv-ml-dev \

        opencv-dev \

        protobuf \

        gdb \

        libsdl2 \

        libgpiod \

        libgpiod-tools \

Appeared the failure message, why??

The version list has v4.1.0, but the error message show nothing provides v4.1.0 for opencv.

nothing provides opencv >= 4.1.0 needed by packagegroup-user-requirements-1.0-r1.noarch

You need to look up PREFERRED_VERSION rather.
