some questions about Boost libraries
hello all .
i have just downloaded the latest boost source codes and compiled them, and configured the stuff as i should have!
and then i tried to compile some examples to see how stuff works, and also to check if everything went well! .
one of the examples ran well! but the other one which you can see below, gave me couple of errors!
Code:
#include<iostream>
#include<boost/filesystem/operations.hpp>
namespace bfs=boost::filesystem;
int main()
{
bfs::path p("second.cpp");
if(bfs::exists(p))
std::cout<<p.leaf()<<std::endl;
}
and errors:
Code:

my question is , how should i know which header file needs which *.lib file!
i think the above errors are due to the absence of a lib file of some kind!
so please help me on this !
and the second question is how can i find more about classes, functions and other useful stuff in boost , just like what we have in C++ Reference [C++ Reference] with examples for each of them , so that i can understand how to use them in my program .
thank you all in advance
