Hi Dennis,

please note that this is not the correct forum for this topic.
The "Installation and Configuration" forum is more appropriate, here.

You need to specify the namespace for file streams.
i.e., the line above should look like the following:

   std::ofstream outFile("outfile.txt",std::ios::app);

This happens because g++ does not enforce ISO/ANSI setup for
compilation, while VC++ on Windows does.
The fix above should solve your problem.

Cheers, Gabriele
