Eclipse, Qt Widgets & gdb possible? [message #1646885]

I've got a project with about 40 classes employing Qt Widgets.

After much pain I've got the makefile to make it, now I'd like to use the MinGW gdb to debug it.

I've managed to get the following simple cpp file to compile and run with gdb :

For this I had to remove this option from the link command : -Wl,s

// Simp1.cpp

int main(int argc, char *argv[]) {

    int k = 0;    //<-----breakpoint

    return 0;
}

however when I add Qt classes to the mix it does not stop at the breakpoint.

Adding and removing -Wl,s to the link command has no effect.

Using the exact same compile commands and link commands as the QtCreator has no effect.

// Simp2.cpp

#include <QApplication>
#include "MyMainWindow.h"

int main(int argc, char *argv[]) {

    int k = 0;         //<-----breakpoint

    QApplication a(argc, argv);

    MyMainWindow mw;
    mw.show();

    return a.exec();
}

Question : is it at all possible to use MinGW gdb on a Qt class project in Eclipse?
yes or no?
