Blank screen in RaspberryPi
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? :(
I recompiled and reinstalled everything from scratch and it worked, UNTILL I installed something in raspberrypi (gpac, for MP4Box tool), and blank screen come again :(
That's strange :|
there is a
Buffer creation failederror, before above errors.
@MajidKamali What do you use on the device? X11? Framebuffer? ...?
eglfs. device is a raspberry pi 3 B+
