If you do get everything working, you just include #include <boost/filesystem.hpp> .
And then the code is boost::filesystem::create_directory(directory_name).
You'll have to download and build boost - let us know if you need help with that :) Once it's installed it's easy, but it can be tricky to get that far if you're new...
In the "include" field, browse for the "include\boost-1_42" subfolder of your Boost installation -- it should be the path in the "base" field with "\include\boost-1_42" tacked on.
That's a misguiding tutorial, it would seem. There is no include/ directory. Just add the base boost directory as an include path. The header files are inside a directory in the main boost directory called boost/ (you can look!).
So if you add the base boost directory as a compiler search path, you can incude boost headers like this: #include <boost/header_file_name.hpp>
Visual Studio? Nonetheless, this problem won't be helped by switching IDEs. Can you tell me the absolute path where you put boost, and the absolute path of the boost folder containing "bjam.exe", "boost.css", "jamroot" and other files.
@OP
Okay, so that is the actual include folder. Presumably you can now continue with the Wiki guide.
However, kbw may have a point. We can see how this goes, but when it comes to building Boost, it might be tricky as I said. But there's no harm in trying :) Just don't get put off if it seems daunting at first.
