QFontDatabase: Cannot find font directory /usr/local/qt5pi/lib/fonts.

[K-Str]

Hello,
in the past I got a lot of good tips here. Thank you!
Now I got an quiet old problem and I know there is only a little knowledge missing.
But I couldn't find a simple solution.
When I start an application (widget) created by
Qt Creator 4.8.0-rc1 (4.7.84)
Based on Qt 5.12.0 (GCC 5.3.1 20160406 (Red Hat 5.3.1-6), 64 bit)
Built on Nov 23 2018 01:25:42
From revision 7c17edcce2
I get some errors :
QFontDatabase: Cannot find font directory /usr/local/qt5pi/lib/fonts.
On the raspberry there is no directory /usr/local/qt5pi/lib/fonts.
In the widget I write some text (font = Ubuntu, 10).
I get some errors on ma LCD-display ( 3.5" with HDMI).
Please has somebody any idea?

Hi,

@K-Str said in QFontDatabase: Cannot find font directory /usr/local/qt5pi/lib/fonts.:

Cannot find font directory /usr/local/qt5pi/lib/fonts.

Do you have that folder on your desktop machine ? If so, simply copy it over to your RPi.

thank you for your tip.
I found a lot of directories called font on my host.

But I have no idea which one I should take.
Which one would you recommend?
