QXcbConnection

[ABILATA]

Dear,

I compiled the karbowallet and when I try to run the ./karbowanec file I got the following outcome:
./karbowanec
QXcbConnection: Could not connect to display
Aborted (core dumped)

Thank you in advance for your help, kind regards

It's strange. Try export DISPLAY=:0 then run wallet

I still got the same outcome:
~/karbowanecwallet/build$ ./karbowanec
QXcbConnection: Could not connect to display :0
Aborted (core dumped)

Is it some remote access? Or maybe it's root? Try export DISPLAY=:0.0

Thank you for your promptness and sorry for my delayed anwer. Yes, it is a remote access, I am doing it in a ubuntu server. Before I could test your suggestion I reinstalled the server (for a different reason) and started everything again. Unfortunatelly now I have a different problem:
karbowanecwallet-Sudo/src/AddressProvider.cpp:7:10: fatal error: QJsonArray: No such file or directory
#include

You need to fix your QT installation.

Indeed, that is like hell to solve for unexperienced people like me. Still trying...
