I cant use console application
-
hi
when i build a console program i cant see results in terminal page . just opened a empty terminal page and doesnt show anythings!
i dont know why and i'll be happy if anyone helps me
-
Can you please post your written code to see, what's wrong?
I am not sure, what you meen with "doesn't show anything". Which system are you using? -
This is far too vague to say anything helpful.
Please say at least which platform you are on and show a meaningful piece of your code.

thanks dears .
i have not any code. just i tested it and didnt get any result .
my simple code is :
@
#include <QCoreApplication>
#include <iostream>using namespace std;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
cout<<"aaaa";
//printf("ssss");
return a.exec();
}
@and i am in ubuntu 12.04 OS with qtcreator 2.5 and qt4.8.1 sdk.
when i execute that code a empty terminal box opens and i can write into but it doesnt any work!

this code is in .pro-file too :
@
QT += coreQT -= gui
TARGET = test1
CONFIG += console
CONFIG -= app_bundleTEMPLATE = app
SOURCES += main.cpp

I'm not quite sure about how this is on Linux, but on the Windows platform applications can be compiled as "Windows" or as "Console" applications. That's a Linker option. If you compile as "Windows", which is the default for GUI apps, then the app doesn't have a console. And even if you run it from a console - or allocate a console at runtime via AllocConsole() function - output to the console via "stdout" or "cout" doesn't work. Bummer! That's because the C Runtime never binds the stdout/stderr or cout/cerr to the console - because it doesn't expect a console to be there. There are some workarounds for that. Maybe on Linux there is a similar issue. I'm not quite sure. Maybe somebody more familiar with Linux can give an answer about that...
