Qt Source code of Jessie Image not working in Buster Image?

[SHUBHAM SINGH RAO]

Hello everyone
I tried to shift and run my source code from raspbian jessie to raspbian buster.
But it is showing errors like
QMainWindow: No such file or directory

Same error with QtGui, QtSql,QFileDialog, QAbstractButton etc.

Why its not running basic libraries of Qt in buster?

Did you installed all needed parts of Qt on buster?
Also, if you have copied the build directory delete it, run qmake and rebuild.
