<DIV><FONT face=Arial size=2>I recently resolved problems with creating and
debugging a KDE MDI project (KScribble example) using KDE2. So, I moved on
to creating and debugging a Qt MDI project (QScribble example which is the same
as the KScribble example only created by choosing Qt MDI project in the
wizard). I overcame two problems when the linker could not find the
libqt.so.2 library. I created a link to the Qt 2.1 library (in the
/usr/lib/qt-2.1.0/lib directory). Also, the autoconf warned about not
finding the KDE2 libraries, so I added "--prefix=/opt/kde2". That seemed
to solve the build. The program runs fine until I decide to exit.
When simply running the program I get a segmentation fault error. When I
run the debugger, the debugger stops at the "isLastView()" method. The
status line says: "No source: 0x804fffa in QScribbleDoc::isLastView
(this=0x1) at qscribbledoc.cpp:73". I understand that the this pointer
(=0x1) is invalid. I did not touch this part of the code (it was generated
by the wizard). If I close the child window within the app, the same
routine is called with a valid pointer. This does not happen in the KDE
MDI project (KScribble). The two (KScribble and QScribble) source codes
are almost identical. Is this a bug or am I missing
something?</FONT></DIV>
