[RESOLVED] Console Application
-
Hello All,
I develop a application that will every X seconds read a file.
This already be done, but I have a big problem: I need keep the app running! I Use QTimer to Define the time of app read the file, but after read the first time the app stops to run.
I just need keep this console app alive until send some kill signal or shutdown the machine.Any one can help me?
Thanks all! -
U should create "QApplication":qt-project.org/doc/qt-5/qapplication instance and call its "exec":http://qt-project.org/doc/qt-5/qapplication.html#exec method.

I'm using QCoreApplication! As you can see:
@
#include <QCoreApplication>
#include <control/control.h>int main(int argc, char argv[])
{
QCoreApplication a(argc, argv);
Control control = new Control(&a);
control->start();
return a.exec();
}@I will try QApplication...

I got this error:
/usr/bin/ld: cannot find -lGL
collect2: error: ld returned 1 exit status
make: *** [KismetLog] Error 1
17:25:54: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project KismetLog (kit: Desktop Qt 5.3 GCC 64bit)
When executing step "Make"I add to .pro this: "QT += core xml xmlpatterns widgets" and change the main:
@
//#include <QCoreApplication>
#include <QApplication>#include <control/control.h>
int main(int argc, char argv[])
{
// QCoreApplication a(argc, argv);
QApplication a(argc, argv);
Control control = new Control(&a);
control->start();
return a.exec();
}

QApplication is only for GUI apps.

Related, but you could use QFileSystemWatcher instead of timer for reading the file... Unless there is a reason why you want to read it every fixed amount of time. :-)
