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

我设计了一个由调用共享库dio.so的主程序core组成的应用程序，以下是我编写的两个食谱：
1- core.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对于这两个配方都是成功的，但问题出在核心的do_package_qa上，它抛出了以下错误：
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]如你所见，我添加了以下代码来处理依赖，但似乎缺少了一些东西，用dio更改libdio也没有解决问题，有什么提示或想法来解决这个问题吗？
#dio.bb
PROVIDES = "libdio"
RPROVIDES_${PN} = "libdio"
#core.bb
DEPENDS += "libdio"
RDEPENDS_${PN} = "libdio"回答 2

也许这里缺少一个空格：
RPROVIDES_${PN} =“libdio”
RDEPENDS_${PN} =“libdio”

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，这些名称是从哪里来的？我不知道，但至少它现在起作用了
