---------------------------------
actually I also tried to install that boost lib follow its install instuction
, after that(maybe not fully success, I am not sure)
I found there is
libboost_thread.so
--------
root@eric-laptop:/home/eric/boost1/boost_1_46_1# ls -l -a /usr/local/lib/libboost_thread.so

hope these help any advencer to debug to make it success to compile/link
thanks a lot in advance, Eric
