The "2 minute" tutorial is rather buggy.

This one is my fault. I am not linking to the proper library.

Yeah, but how to find which is the proper library??

I managed to get it to compile with the following, but it involved a lot of (intelligent) guess work:

g++ boost_example.cpp -o run -lboost_filesystem-mt

The problem is that nowhere it is said what the name of the library is:
http://www.google.com/search?hl=en&q=site:http://www.boost.org/+"boost_filesystem-mt"

Is there an intelligent way to know the name of the library to link to at compile time? (Linux/Kubuntu)
