Even after you post the screen shot:

No way!


Translation: show us the error, crystal balls are after all not anymore as good as they used to be in the 1920th.

The error is:
'QtSingleApplication': No such file or directory at the line: #include <QtSingleApplication>

Ok, franco, let's play a teacher-student stunt. My question is - what to do to make an include file visible for the compiler in a Qt project?

Include the folder, I searched such file in my Qt installation and I can not find it

[wysota]

What do you mean by "include the folder"? What folder? And include it where?

include the folder to the 'additional include path' of my visual studio.
The folder where such include should be stored

So how do you add a folder to a list of directories where your compiler looks for includes?

In the project settings, I don't know why you think to me as a student when I'm not. Is not the first additional path that I added to the
project. Simply I can not find such include, maybe it's part of the commercial version of Qt that I don't have.

Who said it was part of Qt?

The link sent to me http://doc.qt.nokia.com/solutions/4/...plication.html
by Lykurg. I think that's is part of Qt

[wysota]

Then you think wrong. Look at the URL. And then open the URL and click the "Home" link.

If you can't even read a thread correctly and get my name right, I'm not surprised your struggling to use something that is clearly not a part of Qt. You have been told where it can be downloaded, and the package itself comes with instructions on how to install it and use it with your application.

You can't expect us to do everything for you. Some things you have to do for yourself.

Let me explain what Lykurg meant - in his short ironic post he noticed that your post that the compiler gives you an error doesn't bring you (or anybody else) even a step closer to solving the problem because you are not providing any relevant information. A possible response to "the compiler gives error" might be "then fix it". Then you would probably say "How?" and Lykurg would say "I don't know" or something similar. By the way, your screenshot also qualifies for a "no way!" response. If you want help, don't expect us to guess what your problem looks like.

Edit: Yeah, well... I was right about the "no way" thing about a screenshot
