No rule to make target 'VLCQtWidgets/WidgetVideo.h', needed by 'ui_mediaplayer.h'



  • Hy guys, I am developing a media player using vlc-qt. So what I have done till now is I have clone the git repository of vlc-qt and have build that using BUILDING.md and in my '''pro''' file of Qt I have added the path of my vlc-qt installation like below

    INCLUDEPATH+= /home/vinay/vlc-qt/build/include
    LIBS+= -L/home/vinay/vlc-qt/lib -lVLCQtCore -lVLCQtWidgets
    

    and I am trying to make same editor as shown by this example https://github.com/vlc-qt/examples/tree/master/simple-player

    But here What It has done is that he creates one widget in UI file and then promote it to header WidgetVideo.h and class VlcWidgetVideo So I have done the same. The path for header and class I provided in my promoted widget was

    class name:VlcWidgetVideo
    header: VLCQtWidgets/WidgetVideo.h
    

    But when I build my project it shows me below error

    No rule to make target 'VLCQtWidgets/WidgetVideo.h', needed by 'ui_mediaplayer.h'.  Stop.
    

    When I include the header in the project like

    #include "VLCQtWidgets/WidgetVideo.h
    

    The file is included without showing error it meanas my project is able to access this file but when I run this it shows no rule error.
