I'm trying to make a form application under Arch Linux with Qt and C++, but when I try to run my application which is below:
firstWindow.h
#include <QMainWindow>
#include <QLabel>
#include <QPushButton>
#include <QLineEdit>
#include <QLayout>
class firstWindow:public QMainWindow
{
Q_OBJECT
public:
QLabel *lbl;
QPushButton *btn;
QLineEdit *row;
firstWindow():QMainWindow()
{
setWindowTitle("First Window");
QWidget *win = new QWidget(this);
setCentralWidget(win);
lbl = new QLabel("Hello Universe", win);
btn = new QPushButton("Click Click", win);
row = new QLineEdit(win);
QVBoxLayout *main = new QVBoxLayout(win);
main->addWidget(win);
QHBoxLayout *nextTo = new QHBoxLayout();
nextTo->addWidget(row);
nextTo->addWidget(btn);
main->addLayout(nextTo);
resize(200,50);
win->show();
}
};
After compiling it, I get this error:
#qmake -project
#qmake
#make
# ./QtFirstWindow

Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported
It doesn't stop or kill the application, but it also doesn't run it. I think that error isn't about the code that I wrote, because it is a little sample. So how can I deal with that? Any idea?
