Linker error on linux

[Dominik Werder]

Hi all!
I just wanted to try Crypto++.
So I compiled it successfully on Linux (Slackware), gcc version 3.3.4
I tried the following (at the bottom) simple code (it does nothing useful  
yet) from the FAQ and tried to compile it with: g++ -o test  
-I../software/crypto -lcryptopp cr.cpp 2> err
It finds the libcryptopp.a, but gives me hundreds of linker errors,  
starting with:

could anybody help me with this??? I tried for two days now...
