I hope that helps.I vote for using fsteams like bb wrote in his postdandymcgee wrote:Use rdbuf to redirect std::cout to a file:

This is exactly why I recommended rdbuf. Marauder and Falco are overlooking the fact that certain libraries assume std::cout INTERNALLY. I'm not sure that Lua does this, but I know for a fact that SDL does. Though you could try to change and recompile them, it is much easier to just forward the standard out stream to a log file.shawk wrote:But I need lua to print to it also so if lua print function only uses std::cout I would have to make a different function for lua to access the ofstream
Log debuglog("debug.log", true);
debuglog << "Player triggered warp tile at (" << ev.x << "," << ev.y << ")" << std::endl;
Of course, you probably shouldn't instantiate a log in a function that runs more than once, unless you change Log::open to use append mode.Code: Select all

Actually, I seem to have remembered incorrectly. By default, SDL redirects stdout to stdout.txt in the working directory. You have to use some similar hack if you want stdout to go to a console window instead without having to recompile the library with NO_STDIO_REDIRECT set. So it's essentially the opposite of the OP's problem, my bad.Falco Girgis wrote:2) SDL, a C library, uses cout, a function of the C++ standard library? Orly?
