Stdout and stderr redirection question

SDL Development
1

Very strange question, hopefully someone can explain this to me:

I have a singleton class whose constructor is called before main (a
global object, essentially). If I put a cout or cerr statement in the
constructor, the stdout.txt and stderr.txt files, whichever I write
to, don’t get created. If I leave those statements out of the
constructor, or comment them out, the txt files show up and are filled
with my debug statements. Everything else works fine either way.

Is there a simple answer why this happens?

Thanks,

simply because SDLmain hasn’t redirected to files yet since it hasn’t been called.
writing to stdout/stderr before that redirect happens, makes the output go nowhere, until SDLmain runs through.

that’s what I think anyways.

I had the same problem. I tried on MSVC++ 6, MSVC.net, and KDevelope. It
worked on KDevelope but not on the MSVC versions. Also, make sure your
program is calling exit (ie. setting up esc to exit) and you are not just
closing the window.

how about a link to the source code?
