[Solved] QDesktopServices::openUrl segfaults (qt5, linux)

[t.j.a.devries]

Newbie, having this simple program main.cpp:

@
#include <QString>
#include <QDesktopServices>
#include <QUrl>

int main()
{
QString str = "http://qt-project.org/";
QDesktopServices::openUrl(QUrl(str));
return 0;
}
@

and this .pro file:

@
QT += core gui

TARGET = openTest
TEMPLATE = app
CONFIG += console

SOURCES += main.cpp
@

It segfaults on the openUrl statement.
Archlinux, standard Qt5.01 package.

What am I doing wrong?

thanks in advance!

Maybe it needs event loop to be present? I doubt it, though. Try with QUrl::fromUserInput();

Well, everything :)

Your project setup is wrong, and the code in main.cpp is also wrong.
You can not use QDesktopServices in a console application, and you are also missing QApplication instance.

Here is correct .pro file:
@
QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = openTest
CONFIG -= console

TEMPLATE = app

SOURCES += main.cpp
@

The correct main.cpp:
@
#include <QApplication>
#include <QString>
#include <QDesktopServices>
#include <QUrl>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QString str = "http://qt-project.org/";
QDesktopServices::openUrl(QUrl(str));
return a.exec();
}

Thanks, that solved it. Turns out the a.exec() is not needed.

Funny thing is that in qt4 the code I originally posted did work.
