Hi there!
I'am currently developing a game in C++ and SDL.
And I want to have a dos prompt in the background that sais what is going on in the game.
What input is going on what entity are getting created and so on.
I have a dos prompt up but it's just empty, I've included iosteam, and is using namespace std, and I've written "cout << "It's alive"; but the window is empty.
What could be the problem?

There are a couple ways to do this.  Right now SDL is redirecting the output to stdout.txt.  The way I use is to just put "#undef main" right before your main function.  I've seen a few people who said that was bad, but I never got why, and I've never had problems.

On certain platforms SDL likes to do things before and after program execution; an alternate solution is to rewrite your main function like so:

Code:

int main ( int argc, char** argv )
{
    freopen( "CON", "w", stdout ); //on windows and mac

    // the rest of your code
}

You can also compile SDL with a certain flag (NOCONSOLE or something like that) and you won't even need to do the above.  That's how I do it, for reasons I don't recall.


If you're only developing for Windows, #undef main is probably fine though.

You can use the #undef main only on Windows...
