Blank screen in RaspberryPi



  • Hi.
    I cross compiled Qt 5.12.3 for raspberry pi 3 B+ successfully with this link.
    But when I compile and deploy application to raspberry, screen is blank and lots of following error is shown in console:

    QOpenGLShaderProgram::uniformLocation(qt_Matrix): shader program is not linked
    QOpenGLShaderProgram: could not create shader program
    QOpenGLShader: could not create shader
    QOpenGLShader: could not create shader
    shader compilation failed: 
    ""
    

    Screen is a common HDMI monitor.
    What should I do? :(
    Thanks
