Stdout e cout in Win32

SDL Development
1

(I’m using Win32, and I tryed console and windows compilation)

Is there a way to redirect std::cout to the file stdout.txt ?
With printf it works, but std::cout don’t…–
Bye!

2

in this i would be interested too!!

there is a solution to redirect cout to a fltk - textoutput-window,
but it is rather complicated, reimplementing the buffered working
principle of ostream. ( search for “fltk log” )

isn’t there a simpler solution ?

Cool - i’ve tested it in release mode under visualc++ - and the
redirection works already in sdl, if you build a non-console project !!
Only with a console project cout outputs to the console. So - for me
everything is fine. Just try to switch off the console - go to the
linker settings and choose under system : “/SUBSYSTEM:windows” instead
of “/SUBSYSTEM:console” !!!

As I said in my first message, I tryed both windows and console subsytem…
(I always use the windows subsyste, however…) and it doesn’t work…

This is my test program:

#include “SDL.h”
#include

int main(int argc, char *argv[]) {
printf(“i’m printf”);
std::cout << “i’m cout”;
return 0;
}

The stdout.txt file is only:
i’m printf

I’m using VC++ 6 with SP5, under WinNT 4 and WinME.
I’m using the latest version of SDL.–

I’ve found the problem !!!

It WORKS in release mode BUT it DON’T WORKS in debug mode !!!

Now… I’d like to understand why… I didn’t change any compilation/linking
options…
any idea ?–
Bye!

Ok, i’m using visual studio 2003 … And i use stl and “using namespace
std;” - but i do not think that this is the reason…

I use stl too (std::string for example).

Does your sample work only in release mode ?
Have you tryed the debug mode ?–
Bye!

If i use subsystem:windows in debug mode, my cout<<* output goes too
into stdout.txt !!

That’s correct. SDL redirects output to a file so that you have a record
of it for bug reports (it wouldn’t go anywhere else otherwise). You can
modify this behavior by changing the define in SDL_main.c and rebuilding
SDLmain.lib
