在包组中使用RDEPENDS指定版本

Question

我有多个opencv版本，但bibake默认安装了3.4.3版本。

=== 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

yocto官方文档提到了变量

RDEPENDS

支持指定版本的操作符。

然后我在包组中将opencv的版本指定为4.1.0。

SUMMARY = "Requirement packages"
PR = "r1"

inherit packagegroup

RDEPENDS:${PN} = " \
        opencv (>= 4.1.0)\
        libopencv-core-dev \
        libopencv-highgui-dev \
        libopencv-imgproc-dev \
        libopencv-objdetect-dev \
        libopencv-ml-dev \
        opencv-apps \
        opencv-dev \
        protobuf \
        gdb \
        libsdl2 \
        libgpiod \
        libgpiod-tools \
"

出现失败信息，为什么？？

版本列表有v4.1.0，但错误信息显示

nothing provides v4.1.0 for opencv

。

没有提供 packagegroup-user-requirements-1.0-r1.noarch 所需的 opencv >= 4.1.0

我尝试将版本条件设置为

> 2.0

后成功构建了镜像，但版本仍然是v3.4.3 for opencv。

SUMMARY = "Requirement packages"
PR = "r1"

inherit packagegroup

RDEPENDS:${PN} = " \

如何指定包组中的包版本？谢谢

您需要在 local.conf 中设置 PREFERRED_VERSION_package = "version"。 对于你的情况：

PREFERRED_VERSION_opencv =“4.1.0”
