[Boost-users] Desperately in need of help!

Hi all!

I have an application which uses STLport 5.0.0, libtorrent (which in 
turn uses Boost). What I have done is that I have compiled the boost 
libraries for msvc7.1-stlport. I only uses three, i.e. filesystem, 
date_time and thread. My boost version is 1.33.1

So the problem occurs when my application is linking. Then I get a lot 
of LNK2005 link errors. I have no problems with compiling my code and 
use the boost libraries it's only when I'm about to link it fails. The 
errors says, in general, that a lot of things already are defined in 
libboost_xxx_mt-sp...
I guess that if I post some of my errors it will be easier for those who 
wants to help me :) So here we go...

1.

2.

I would really appreciate if anyone could help me out here. Since I am 
new to C++ etc. I have major difficulties in intepreting the error 
messages.

Best regards
