Question

I’m using the latest Qt SDK (2.4.0) and am having problems getting the visual studio 2008 CDB working properly. I have a experienced the following 2 problems which I think are related

1. I have an assert that is failing. When that assert fails I see the Visual Studio dialog box asking me if I’d like to Abort, Retry, or Ignore. If I choose Retry, the program does not break as it should, instead it just continues executing. However, if I put a break point before that assert, and then step over that line within the debugger then when I hit Retry the program does break as expected.

2. All break points that are in place before execution starts are hit correctly. However, if I attempt to add a break point after execution starts then that break point is ignored. But, if while stopped, I add more break points, then those are correctly hit.

It would appear that the debugger is only working once I manually stop it with a break point. Does anyone know what is going on here?

For your first question I guess you doesn’t allocate an “object” you use.
Something like:

//header file:
class Foo : blabla
{
public:
    Foo();
private:
    QSomething *m_fie;
};

//source file:
Foo::Foo()
{
   m_fie->IWant2UseItNow();
}

if your debugger doesn’t work you could try add:

#include <QDebug.h>

and several print string. i.e.:

//source file:
Foo::Foo()
{
   qDebug() << "1";
   m_fie->IWant2UseItNow();
   qDebug() << "2";
   ...
}

For your last question qtcreator helps you work less. It does not do something better then other IDE, but it’s integrated with qt. It can help you avoid a lot of .pro file configuration. Infact to debug your app correctly you should define in your project file:

CONFIG +=    debug_and_release

or at least:

CONFIG += debug

qtcreator does it for your.
