[Boost-users] boost::thread

Does using thread classes from boost need additional library files other than header files ? I am getting the following error when I use the thread class: /usr/include/c++/3.2.3/bits/stl_heap.h:188: undefined reference to `boost::thread::thread[in-charge](boost::function0boost::function_base > const&)' I also see 'libboost_thread-gcc-mt-d-1_31.so.1.3.0' library under boost/bin/... Does this have to be used ? Thanks in advance Raja
