SEGV error when running an application on arm

[wowy]

Hi,

I am trying to run a little application on my target (simply a window, no button, no text, just a window) but when i try to run it like :
./app -qws

Nothing appear on screen and i get a "SEGV" message on the terminal.
After searching for this kind of error i often read that i could happen because a program try to have acces to a part of the memory who either don't exist on which it don't have the right to use. (i chmod 777 the program to give it all rights)

I know the compiler is working because i can generate a little .c file which will make a print 'hello world' on the terminal but now i would like to use the screen with my board

In Qt creator the files are :
mainwindow.h :

#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
    Q_OBJECT
public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
private:
    Ui::MainWindow *ui;
};
#endif // MAINWINDOW_H

A main.cpp:

#include "mainwindow.h"
#include <QApplication>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}

and a mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}
MainWindow::~MainWindow()
{
    delete ui;
}

Hi,

Did you try running your application through the debugger ?
