Thread Problems (i think)

I can't understand why "Cout Test" did not printing. I think this is thread problem.

But you application doesn't use threads... Does the application output anything at all for you?

i think signals and slots are using threads.
app output only via qDebug() or cerr.

What operating system are you using?

Ubuntu 7.04 Feisty
does this matter?

Does this output anything?

Code:

---

#include <iostream>
int main(int argc, char **argv){
  std::cout << "TESTING" << std::endl;
}

---

Compile it using qmake please, just like you would for a regular Qt app.

yeap! output TESTING =))

Seems to be missing std::endl.

std::endl is not obligatory at all

cout works only on stdout, so you need to tell qmake this is a console app.
Therefore add CONFIG += debug console to the pro file.

In a GUI app you can try to output something to cerr. It might work.

But lack of it prevents the output buffer from being flushed. Try adding it like J-P suggested.

He's using Linux, so that's not the case here. That is why I asked about the OS he uses.
