[Boost-users] problems running boost_thread library

I have tried to run an example using the latest release of boost and I got the following error: error while loading shared libraries: libboost_thread-gcc41-mt-1_34.so.1.34.0: cannot open shared object file: No such file or directory I have boost installed correctly and I just added -lboost_thread-gcc41-mt-1_34. the problem is not in the code because I have also tried with an empty main and the problem persists. and the fact is that all the libraries are in the same directory (/usr/local/lib) if any idea I'll appreciate it very much to you response me at yperaltag@gmail.com thanks in advance.
