Linking problem Windows 7 (64 bit) Qwt 6.1.0-rc3 + Qt 5.0.2

"VisualDiscretizerWin.exe - Entry Point Not Found
The procedure entry point __gxx_personality_sj0 could not be located in the dynamic link library libstdc++-6.dll"

The dll file is not accessable from the release sub-folder, so what you could do is copy the libstdc++-6.dll file to release sub-folder (it can be found in MinGw\bin folder).

Further you need other dlls, copy all the required dlls to release sub-folder

Thanks! I copied the libstdc++-6.dll file in the folder, and now it's not giving that error anymore.

However, it's getting weirder. After I copied the .dll inside the release folder, the executable crashed with no messages (!) every time I tried to run it, even after recompiling everything :-O The current main.cpp file is:

// main class for the visual discretizer application
 
// Qt/Qwt classes
#include <QApplication>
 
// local classes
#include "Interval.h"
#include "VisualDiscretizerMainWindow.h"
 
using namespace std;
 
int main(int argc, char* argv[])
{
	cout << "Wow, now I am running!" << endl;
 
	// create qt application
	QApplication app(argc, argv);
 
	// associate it to main window
	QMainWindow* mainWindow = new QMainWindow;
	Ui::VisualDiscretizerMainWindow vdMainWindow;
 
	// execute
	vdMainWindow.setupUi(mainWindow);
 
	// show window
	mainWindow->show();
 
	// return
	return app.exec();
}

// main class for the visual discretizer application

// Qt/Qwt classes
#include <QApplication>

// local classes
#include "Interval.h"
#include "VisualDiscretizerMainWindow.h"

using namespace std;

int main(int argc, char* argv[])
{
	cout << "Wow, now I am running!" << endl;
	
	// create qt application
	QApplication app(argc, argv);
	
	// associate it to main window
	QMainWindow* mainWindow = new QMainWindow;
	Ui::VisualDiscretizerMainWindow vdMainWindow;
	
	// execute
	vdMainWindow.setupUi(mainWindow);
	
	// show window
	mainWindow->show();

	// return
	return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Do you have any advice?

Can you use the debugger and see where it is crashing.

BTW mainWindow is not being deleted!
