AM5718: I have an issue with QT5 running on am5718 board.

Hello,

Are you able to run other Qt examples located in the directory "/usr/share/qt5/examples"?Also, have you tried to disable Weston while running your application?

Regards,
Krunal

Hello Krunal.

Now, I've begun to think that this problem is not related with QT but with my linux system somehow. 

I've changed the compilation setting back to original when there was no 61850 shared library linked.

And I compiled the application, executed it and got the following error.

My colleagues didn't get such errors after the compilation of the same code. Is there a problem with my linkage of my shared library to affect the Linux system somehow. I've googled the possible solution to my error but still have no clue. 

Please save me from this endless swamp of debugging. 

Thank you!
