Qt Building Error While Building Cross Compile for Raspberry pi 4

Faruk

Hello.

I struggle for cross compiling for Raspberry pi 4. My OS is Ubuntu 20.04. I builded cross compile platform and I have been run simple quick application. (I created project on PC and I could see output window on Raspberry pi screen).

I want run more big project on Raspberry pi4 with cross compile. I want edit code on my PC and I want see output on Raspberry pi 4. I have been worked this project on Raspberry pi 4 without qt.

I tried run qmake for .pro file and I compiled the resulting makefile file. It's working. I want do same process with cross compile but I have errors this place. Qt does not find some .so files but I checked and this files are exist on the specified path.

P.S. I used this commands when I building cross compile. https://github.com/PhysicsX/QTonRaspberryPi/blob/main/qt5.14.2onRaspberrypi

My .pro file this:

QT += quick widgets serialport multimedia
CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Refer to the documentation for the
# deprecated API to know how to port your code away from it.

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.

And my compiled output(Just errors): https://pastebin.pl/view/cbeede8a

How can I fix error ?

Thanks
