[QT] I can't debug my applications

[claudio-cit]

Hello guys, I'm new here. I hope you can help me.

I'm using code::blocks with QT and MinGW installed on Windows Xp.

I've done a new QT4 project and specified the QT folder.

The c++ code is ok, because I can compile by terminal the release and it works.

I get a lot of errors building and running the debug: it doesn't link the QT libraries. How I can specify the right place where to pick them to codeblock?

Thank you, C.

p.s.

CODE:

#include <QApplication>
#include <QFont>
#include <QPushButton>
#include <QWidget>
 
class MyWidget : public QWidget
{
    public:
        MyWidget(QWidget *parent = 0);
    };
MyWidget::MyWidget(QWidget *parent)
    : QWidget(parent)
{
    setFixedSize(200, 120);
 
    QPushButton *quit = new QPushButton(tr("Quit"), this);
    quit->setGeometry(62, 40, 75, 30);
    quit->setFont(QFont("Times", 18, QFont::Bold));
 
    connect(quit, SIGNAL(clicked()), qApp, SLOT(quit()));
}
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    MyWidget widget;
    widget.show();
    return app.exec();
}

#include <QApplication>
#include <QFont>
#include <QPushButton>
#include <QWidget>

class MyWidget : public QWidget
{
    public:
        MyWidget(QWidget *parent = 0);
    };
MyWidget::MyWidget(QWidget *parent)
    : QWidget(parent)
{
    setFixedSize(200, 120);

    QPushButton *quit = new QPushButton(tr("Quit"), this);
    quit->setGeometry(62, 40, 75, 30);
    quit->setFont(QFont("Times", 18, QFont::Bold));

    connect(quit, SIGNAL(clicked()), qApp, SLOT(quit()));
}
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    MyWidget widget;
    widget.show();
    return app.exec();
}

How did you install QT libraries?

[claudio-cit]

I installed QT 4.4 with MinGW and followed the go-ahead-buttons during the installation. How do I should? Is there something to set up and/or compile?

[claudio-cit]

I've tried with this comand:

C:\Qt\4.4.0\src>qtvars.bat compile_debug

and now this is the situation:

1. I click on Tools > qmake
2. I click on Bulid > Build
3. I click on Build > Run

and after the 3rd step I get an allert:

"It seems that this project has not been built yet. Do you want to build it now?"

4. Obviously I click yes but it just build it without running. I've checked also on process list.
If I click no it open the dos prompt and behave like if the program was launched, but it's not.

But actually after 3rd step it's already built and if I go on the folder and I click it, it runs.

Pretty strange, isn't it? It's pretty annoying too.. who knows how to fix it?
