Eclipse C++ - output to window DOS

Answer 1

A simple solution, which I've been using for ages now, is opening a command prompt yourself and running the executable manually. An advantage of this method is that you can set your "DOS" window's size to anything you want. (Right now I'm using a 120x50 window with 8192 lines of scrollback buffer.) Another one is that you will never lose your console output; in fact, you'll be able to see outputs from past runs. (8192 lines is A LOT unless you're printf-debugging a tight loop.)

An alternative to terminating your program from the taskbar is using the red icons on the top right corner of the Eclipse "Console" window.

Answer 2

It sounds like your application isn't terminating on its own and you didn't build in any sort of interface that would allow you to kill the program. This sounds like a bug in your code and not an Eclipse issue. If issuing a Ctrl+C in the console won't kill your program, then look into coding something that will let you kill your app with keystroke or input sequence.

If you want to run your app in a command console, then open a normal command console, browse to the folder containing your project, and run the compiled executable from the console instead of doing it through the Eclipse interface.

Answer 3

Is your program's entrypoint main() or WinMain()? There may also be a setting/link option for the "subsystem," console or Windows I think they're called in Visual Studio.

Anyway, if your program is starting up via WinMain, the expectation is that you'll have a Windows form of some sort through which the user can control the program. If you use main(), then your program should automatically trigger the opening of a console window.

Look up AllocConsole() on MSDN (or google it) if you are using WinMain() intentionally and want a console window to also open up. There's some trickery also available via google search that can hook stdout to this console, but at this time I don't remember what it is. (You basically redirect the stdout handle to your new console.)

Good luck.
