Yocto build: "unable to find a match"

I am trying to build a custom QT application. However bitbake is unable to find the application, while building rootfs.

I tried a number of things:

  1. Added ALLOW_EMPTY_${PN}
  2. Added FILES_${PN}
  3. Removed _ and - from application name
  4. added IMAGE_INSTALL += qtsimplecalc. If I remove this, it builds, but the application is missing from rootfs.
  5. Even github repo. was not getting cloned, so I manually cloned it.

Here is qtsimplecalc.bb

Solution

  • This error is usually due to an empty package, which means that there is something wrong with your do_install that is not installing something in the ${D} folder which is ${WORKDIR}/image

    The issue is that you are inheriting qmake5 after you defining your own do_install and qmake5 has its own do_install that will run the install target on the generated Makefile out of your simpleCalculator.pro file:

    ####### Install

install:  FORCE

uninstall:  FORCE

FORCE:

    The simple solution to this is to move inherit qmake5 before your do_install.

    Also, here is the version of the recipe that uses the git URL instead of local files:

    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"

    You can check the do_install script run.do_install under ${WORKDIR}/temp.

    To make the install process handled by qmake, you can add the following to simpleCalculator.pro file:

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

    and then remove your custom do_install task in the recipe.

    This will activate the original do_install of the qmake5 class that will trigger make install target which will have the following content:

    ####### 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:
