[Boost-users] First time using the boost libs and stuck horribly

First of all, apologies if this information can be found somewhere else. I
couldn't find it anywhere on the internet. 

Now to the real problem. I'm simply trying to utilize the boost libraries
(filesystem in particular) in my program. I'm just trying to even run the
example programs. I'm using Visual C++ 6.0 sp5.
I figured out how to compile it by including the directory where boost is. So
the example program compiles perfectly fine. Then the shit hits the fan, every
reference to any boost object gets an unresolved external error. I have no clue
why this is happening, and the most frustrating part is I cannot find
information anywhere on the internet on how to make it work. I find lots of
references telling me how great it is, but I cannot use it!
