Native Build von Qt5 on Raspberry Pi 3 errors: Unable to query physical screen size, defaulting to 100 dpi. To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
I have created a GUI (with QtDesigner (Qt5) as external tool of PyCharm), and want to run on my Raspberry Pi 3. I've used this guide link text
I get this error message:
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
In my "output" file I have "FontConfig ............. No" instead of "FontConfig ............. Yes",
I also have at
pi@raspberrypi~/opt/qt5$ which qmake /usr/bin/qmake
pi@raspberrypi~/opt/qt5$ which qmake /usr/local/qt5/bin/qmake
I also have a full-screen GUI on my Raspberry Pi without font-text, although I did exactly the same.
I need help please
Did you try to set the QT_QPA_EGLFS_PHYSICAL_WIDTH etc?
thx for your reply, yes i try to set all QT_QPA_EGLFS_PHYSICAL_WIDTH = 194, QT_QPA_EGLFS_PHYSICAL_HEIGHT= 110
QT_QPA_EGLFS_DEPTH= 20 (all im mm for 7" Touchscreem Display). But i'm still having the same problems.
Does anyone have any other suggestions?
