Название: QT debug Отправлено: PoX от Октябрь 13, 2012, 16:55 Dear Team,
I have one question. I have a program written by QT 4.3.3. My program had worked in the past. But after format of OS the program couldn't work. It says: "QWidget: Must construct a QApplication before a QPaintDevice". I have not changed anything in source of Program. Just have installed OS, QT and want to use the program. Maybe anyone can suggest what is the problem? OR Please help me to debug the program and find the problem. How can I do it on Linux via Command Line. I have used Debian linux, when my program had worked. Now I have tried on Debian and Centos and the same problem. Thanks in advance.
