QMAKE_EXTRA_COMPILERS dependencies issue



  • All

    I have Qt project which contains .ts-file and .qrc-file containing reference to generated .qm-file. We do not store .qm-files in our version control system. The issue here is that when I check out source code and run "make", I'm getting error

    @RCC: Error in 'CoreGeneral.qrc': Cannot find file 'core.general_en.qm'@
    

    I created updateqm.pri files to get .qm files generated before build, this file I include to my .pro files

    @!contains(QMAKE_EXTRA_COMPILERS, updateqm) {
    updateqm.input = TRANSLATIONS
    updateqm.output = ${QMAKE_FILE_BASE}.qm
    updateqm.commands = $$[QT_INSTALL_BINS]/lrelease -idbased ${QMAKE_FILE_IN} -qm ${QMAKE_FILE_BASE}.qm
    updateqm.CONFIG += no_link target_predeps
    QMAKE_EXTRA_COMPILERS += updateqm
    PRE_TARGETDEPS += compiler_updateqm_make_all
    }
    @
    But again, I'm getting this error, though .qm files eventually get generated.
    Compile output looks like this

    @C:\Qt\Qt5.2.1\5.2.1\msvc2012\bin\lrelease -idbased core.general_en.ts -qm core.general_en.qm
    C:\Qt\Qt5.2.1\5.2.1\msvc2012\bin\uic.exe PSGHTMLDisplay.ui -o GeneratedFiles\ui_PSGHTMLDisplay.h
    C:\Qt\Qt5.2.1\5.2.1\msvc2012\bin\rcc.exe -name CoreGeneral CoreGeneral.qrc -o GeneratedFiles\qrc_CoreGeneral.cpp
    RCC: Error in 'CoreGeneral.qrc': Cannot find file 'core.general_en.qm'

    Updating 'core.general_en.qm'...
    Generated 108 translation(s) (0 finished and 108 unfinished)@

    So, for me it looks like RCC starts processing .qrc file before lrelease finished generating .qm-files.

    Is there any approach to avoid this issue?

    P.S. I tried using QMAKE_EXTRA_TARGETS to create pre-build event that will be generating .qm-files before any other target will be started but it didn't work for me. I used approach described here "link":http://blog.mgsxx.com/?p=2180

    Briefly, the approach of creating pre-build event is like below

    @# создаем файл-заглушку
    !exists($$OUT_PWD/.beforebuild) {
    system(@echo aaa > $$system_path($${OUT_PWD}/.beforebuild))
    }

    QMAKE_EXTRA_TARGETS += before_build makefilehook
     
    makefilehook.target = $(MAKEFILE)
    makefilehook.depends = .beforebuild
     
    POST_TARGETDEPS += .beforebuild
     
    before_build.target = .beforebuild
    before_build.depends = FORCE
    before_build.commands = @echo our command@

    Hi and welcome to devnet,

    It's been some times since I've used that but shouldn't you rather use PRE_TARGETDEPS ?

    I used all combinations but with no luck, unfortunately
