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