Run console application directly from directory using double click

[atomic]

Hi,

I have a simple console application and when I compile and run in Qt Creator it works fine, when I run it from terminal ( Ubuntu ) it works fine but when I try run it directly from directory using double click it doesn't work - nothing happens.

But GUI application ( using widgets ) I can run directly from directory using double click...

Maybe someone know what I am doing wrong?

Most likely cannot find the libraries it depends on.

What does the program do?
I.e. how did you determine that it did not run?

This application doesn't do anything - it is a simple example for console application.

Because I don't see the console.

I am suprised that the gui application without all dependency works fine...
But ok, I will try to copy to directory all dependency and then see if it works.

Why would you? Programs do not open terminals on their own.

Thanks Wysota,
I just starting with linux system and I thought that console application I can run equivalent how in windows.

Update:
I wrote bash script which can run my console application



#!/bin/bash
gnome-terminal -e "./name_of_my_app"


and in file properties I check - allows the file to be executed.

Now it works fine.
Thanks one more time.

If it does nothing, it is difficult to know if it has run at all.
Not that it matters, because it wouldn't have done anything anyway :)

Since your other programs work I would just assume this one does as well and just does what it is supposed to do: nothing

You can.
If the program does nothing, then it won't do anything on Windows either.

It is like that it also worked fine before.
But since "working" means not doing anything it is nearly impossible to determine whether running it in a terminal changed anything.

You should really implement some functionality that affects the system in some way, e.g. writing a file, before you determine that it does indeed not run when launched directly.

In my experience, running even a "do-nothing" program on Windows (up to and including Win 7) by double-clicking the file name will at least briefly post an MS-DOS command window. Maybe this is happening too quickly to be noticed or the window is behind others, but I am certain that it is still happening. One way to test would be to simply add a sleep() statement with a few seconds' delay to main().

It depends whether the program has the console activated or not.

Well, yes. I don't know if I have ever written a non-GUI app that didn't include console activation. I suppose servers / services would not ordinarily activate a console. In Visual Studio at least, it takes a little bit of effort to create a non-console, non-GUI app.
