Yocto：包需要共享库，但在 RDEPENDS_ 中找不到提供程序？

Question

我设计了一个由主程序

core

组成的应用程序，它调用共享库

dio.so

，这是我写的2个食谱：

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`对于这两个食谱都是成功的，但问题在于

do_package_qa

对于核心，它会抛出以下错误：

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]

正如你所看到的，我添加了以下内容来处理依赖关系，但似乎缺少了一些东西，用

libdio

更改

dio

也没有解决问题，有任何解决问题的提示或想法吗？

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

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

Answer 1

我通过添加以下行解决了问题：

#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，这些名称是从哪里来的？我不知道，但至少现在可以了

Answer 2

有时共享状态缓存会存储旧版本的库。 尝试清理缓存并重新构建：

bitbake <yourapp> -c cleansstate
bitbake <yourapp>

Answer 3

也许缺少空格：

RPROVIDES_${PN} =“libdio”

RDEPENDS_${PN} =“libdio”
