Installation of Qt Creator (Any version)

astello_

Thank you for your quick response.

The last attempt to install Qt Creator I installed the last version available in the Qt Website.

When I introduced (by hand) a "Hello World" program I got this error (“Extra characters after test expression”) for every code line.

Any suggestion?

Thank you again.

SGaist

Can you show your code as well as your pro file ?

astello_

//Code as an "Empty qt project"

#include <iostream>
using namespace std;

void main()
{
cout << "Hello World " << endl;

}

//.pro file here https://drive.google.com/file/d/0B0DYQ85rcVhoVzIzMVIyei1FTW8/edit?usp=sharing

SGaist

What does c++ code do in your pro file ?

astello_

I get no action. Only a message for every code line. The one I mentioned before.

SGaist

That's normal, the pro file is not the place to write c++ code. Create a new default widget project and you'll see

astello_

Yes, I suppose that the code has to be written in the .cpp file and that for each project, a .pro and a .cpp file are automatically created. Aren't they?

My .cpp file is not created.

SGaist

Did you create a new Qt Widget Application like a suggested ?

Hi dear SGaist :*

astello_, Dear friend follow me in below steps:

Run Qt Creator
Click on New project
Select Qt Widgets Application and press Choose
Type a name for ur project and click on Next
In this window select compiler and press Next **Note that if you use from MSVC you should download version of Qt Creator which is compatible with Visual Studio.
Here just click on Next and after it Finish
Look left side of Qt Creator and open main.cpp from Source folder
Add my new code line in main.cpp then Run it
@
#include "mainwindow.h"
#include <QApplication>

#include <iostream> // Add This Line
using namespace std; // Add This Line

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;

cout<<"Hello World :)"<<endl; // Add this line

w.show();
return a.exec&#40;&#41;;

}
@

After run "Hellow World :)" will print on Application output in bottom of Qt Creator
say ur experience after u doing it

@ a.jafarabadi Qt Creator can use MSVC or MinGW indifferently. It's Qt's version which must match.

dear SGaist yes, it's true. we all now always the least version is better :) and the least version have some sub-version which you better now. in that post i want to say if my friend using from visual studio compiler it's good that download Visual studio sub-version of qt

Thank you for your help.

You two are right. If I follow these steps I can do it, but what I need is to open an Empty Qt project.

Here, when I write my code and compile it, it is impossible to run in terminal.

I get the message: "Press return to close this window".

I feel that we are close to the solution but I can't find it.

What do you think?

Thank you again.

SGaist

What do you mean by run in terminal ?

In any case, running an application outside Qt Creator requires the same step as you would have to do in order to deploy it on another computer.

astello_

Run in terminal = Projects (on the left side Menu) -> Run -> Run in terminal marked

SGaist

What project did you create ?

astello_

Empty Qt project

SGaist

Do you mean a console application ?

astello_

Yes.

New File/project -> Other project -> Empty Qt project. That's what I need.

SGaist

Then it's not a console application. You asked for an empty project so you have to write everything yourself. What did you write for this project ?

astello_

#include <iostream>

using namespace std;

int main()
{
cout << "Hello" << endl;

}
