Program crash

[Pragya]

Hi all,
I am having the following pro file

TEMPLATE = lib
TARGET = myplugin
HEADERS = myplugin.h
SOURCES = myplugin.cpp
QT += sql
QT += gui
CONFIG += qt plugin


In the class implementation when i am trying to create any object say qDebug, it crashes.


bool myplugin:: open( )
{
qDebug() << "error" ; // crashes
return true;
}

even I tried creating QMessageBox , the program crashes.
Can anyone sort out my problem.

I'm sure it's not the qDebug() statement that causes the crash. Have you tried debugging?

[Pragya]

I am calling the built library from another application, there
the statement such as qDubug causes crash.

[wysota]

Does it work if you remove the qDebug() call? And what happens if you call qDebug() from that other application? Is is a Qt based app?

[Pragya]

Yes it works when I remove it, the other application is Qt application

[wysota]

Again, do qDebug() statements work inside the other app?

[Pragya]

Yes it works.

Did you try debugging?
