Yocto 构建：“无法找到匹配项”

问题描述 投票：0回答：1

我正在尝试构建自定义 QT 应用程序。但是，在构建 

bitbake
时，
rootfs
无法找到该应用程序。

我尝试了很多事情：

  1. 已添加
    ALLOW_EMPTY_${PN}
  2. 已添加
    FILES_${PN}
  3. 从应用程序名称中删除了 
    _
    和 
    -
  4. 添加
    IMAGE_INSTALL += qtsimplecalc
    。如果我删除它，它会构建，但应用程序会从 
    rootfs
    中丢失。
  5. 甚至 github 存储库。没有被克隆，所以我手动克隆它。

这里是

qtsimplecalc.bb

此错误通常是由于空包造成的，这意味着您的 

do_install
有问题，没有在 
${D}
文件夹中安装某些内容，即 
${WORKDIR}/image

问题是，在定义自己的 

inherit
后，您正在 
qmake5
ing 
do_install
并且 
qmake5
有自己的 
do_install
，它将在您的 
 中生成的
install
 上运行
Makefile
 目标simpleCalculator.pro
文件：

####### Install

install:  FORCE

uninstall:  FORCE

FORCE:

解决此问题的简单方法是将 

inherit qmake5
移到 
do_install
之前。

另外，这里是使用 git URL 而不是本地文件的配方版本：

SUMMARY = "Qt Simple Calculator Application Recipe"   
DESCRIPTION = "This recipe builds a Qt project for a simple calculator application."   
LICENSE = "MIT"   
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"   
     
DEPENDS += "qtbase"   

SRC_URI = "git://github.com/vpapadopou/qt-simple-calculator.git;protocol=https;branch=master"
SRCREV = "1af09d43f9a41ad3136a4fac9db63b9542692f91"

S = "${WORKDIR}/git"   

inherit qmake5
     
do_install() {   
    install -d ${D}/opt/qtsimplecalc/   
    install -m 0755 simpleCalculator ${D}/opt/qtsimplecalc/   
}   
    
FILES:${PN} += "/opt/qtsimplecalc/simpleCalculator"

您可以检查

do_install
下的
run.do_install
脚本
${WORKDIR}/temp
。

要使安装过程由 

qmake
处理，您可以将以下内容添加到 
simpleCalculator.pro
文件中：

target.path += /opt/qtsimplecalc/
INSTALLS += target

然后删除配方中的自定义 

do_install
任务。

这将激活 

do_install
类的原始 
qmake5
，该类将触发 
make install
目标，该目标将具有以下内容：

####### Install

install_target: first FORCE
    @test -d $(INSTALL_ROOT)/opt/qtsimplecalc/ || mkdir -p $(INSTALL_ROOT)/opt/qtsimplecalc/
    $(QINSTALL_PROGRAM) $(QMAKE_TARGET) $(INSTALL_ROOT)/opt/qtsimplecalc/$(QMAKE_TARGET)
    -$(STRIP) $(INSTALL_ROOT)/opt/qtsimplecalc/$(QMAKE_TARGET)

uninstall_target: FORCE
    -$(DEL_FILE) $(INSTALL_ROOT)/opt/qtsimplecalc/$(QMAKE_TARGET)
    -$(DEL_DIR) $(INSTALL_ROOT)/opt/qtsimplecalc/ 


install: install_target  FORCE

uninstall: uninstall_target  FORCE

FORCE:
