STL & hash_set problem

[Unrul3r]

Hello,

I'm new to the forums and this is my first post (not sure if it's in the right place) and i'm also a beginner at programming in c++, so bear a little with me.

I'm trying to get the STL hash_set included in my code but i'm getting some wierd problems compiling (very big compiling error). Firstly, i don't know if i installed STL correctly (extracted to include dir in devc++). Second, i included the hash_set (#include <hash_set.h>) in a simple example program and getting the huge compile error. I think it's a very common problem but due to my ignorance i'm unable to solve it. I hope no additional information is required as i think many of you may already know what is going on.

Thanks,
Unrul3r
