package - Yocto：包需要共享库，但在 RDEPENDS_ 中找不到提供程序？

问题描述

core我设计了一个由调用共享库的主程序组成的应用程序dio.so，这些是我编写的 2 个配方：

1-核心.bb：

#
# This file was derived from the 'Hello World!' example recipe in the
# Yocto Project Development Manual. 
#

SUMMARY = "Core "
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "file://* "
      
S = "${WORKDIR}/sources"

do_compile() {
    oe_runmake STAGING_PATH=${STAGING_DIR}
}

do_install() {
    oe_runmake install IMAGE_PATH=${D}
}

DEPENDS += "libdio"
RDEPENDS_${PN} = "libdio"

2- dio.bb：

#
# This file was derived from the 'Hello World!' example recipe in the
# Yocto Project Development Manual. 
#

SUMMARY = "DIO"
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
PN = "dio"

SRC_URI = "file://* "
      
S = "${WORKDIR}/sources"

do_compile() {
    oe_runmake
}

do_install() {
    oe_runmake install IMAGE_PATH=${D} STAGING_PATH=${STAGING_DIR}
}

PROVIDES = "libdio"
RPROVIDES_${PN} = "libdio"

do_compile,do_install和 do_package`` 对两个配方都成功，但问题出在do_package_qa核心上，它会引发以下错误：

bitbake -c do_package_qa core
core-1.0-r0 do_package_qa: QA Issue: /usr/bin/core contained in package core requires libdio.so()(64bit), but no providers found in RDEPENDS_core? [file-rdeps]

如您所见，我添加了以下内容来处理依赖关系，但似乎缺少某些东西，更改也没有解决问题，关于解决问题的任何提示或想法libdio？dio

#dio.bb
PROVIDES = "libdio"
RPROVIDES_${PN} = "libdio"

#core.bb
DEPENDS += "libdio"
RDEPENDS_${PN} = "libdio"

标签： packageshared-librariesembedded-linuxyocto

解决方案

我通过添加以下行解决了这个问题：

#core.bb
DEPENDS += " libdio"
RDEPENDS_${PN} += " libdio.so()(64bit)"

#dio.bb
PROVIDES = " libdio"
RPROVIDES_${PN} += " libdio.so()(64bit)"

所以我只是在错误消息中使用了相同的名称，这些名称从何而来？我不知道，但至少它现在有效
