[Boost-users] undefined reference to Thread ( Newbie )

Hello all, I am trying to compile and use the Boost 1.54 libraries and have run into a dead end. I compiled and installed the libraries like mentioned in the documentation: ./bootstrap.sh./b2 install I even tried a complete reinstall using: ./bootstrap.sh./b2 threading=multi install I have linked using -lboost_thread and -L<path to boost>/bin.v2/libs. boost_system is also linked in the same manner. i am still getting the following linker errors: undefined reference to boost::thread::start_thread_noexcept() undefined reference to boost::thread::join_noexcept() I am using gcc 4.6.3 on Ubuntu 12.04 in eclipse. Does anyone know how i can fix this? Best, Sahil
