Re: [Boost-users] boost bind() error for creating thread

thanks, But, this time, I got strange errors : I cannot find where my code is wrong. Any help is really appreciated. /tmp/ccnnkCEQ.o: In function `thread_data_base':/boost_1_45_0v/include/boost/thread/pthread/thread_data.hpp:67: undefined reference to `vtable for boost::detail::thread_data_base'/tmp/ccnnkCEQ.o: In function `interruption_checker':/boost_1_45_0v/include/boost/thread/pthread/thread_data.hpp:97: undefined reference to `boost::detail::get_current_thread_data()'/tmp/ccnnkCEQ.o: In function `boost::condition_variable::wait(boost::unique_lockboost::mutex&)':/boost_1_45_0v/include/boost/thread/pthread/condition_variable.hpp:55: undefined reference to `boost::this_thread::interruption_point()'/tmp/ccnnkCEQ.o: In function `boost::shared_mutex::lock()':/boost_1_45_0v/include/boost/thread/pthread/shared_mutex.hpp:129: undefined reference to `boost::this_thread::disable_interruption::disable_interruption()'/boost_1_45_0v/include/boost/thread/pthread/shared_mutex.hpp:137: undefined reference to `boost::this_thread::disable_interruption::~disable_interruption()'/boost_1_45_0v/include/boost/thread/pthread/shared_mutex.hpp:137: undefined reference to `boost::this_thread::disable_interruption::~disable_interruption()'/tmp/ccnnkCEQ.o: In function `boost::shared_mutex::lock_shared()':/boost_1_45_0v/include/boost/thread/pthread/shared_mutex.hpp:59: undefined reference to `boost::this_thread::disable_interruption::disable_interruption()'/boost_1_45_0v/include/boost/thread/pthread/shared_mutex.hpp:66: undefined reference to `boost::this_thread::disable_interruption::~disable_interruption()'/boost_1_45_0v/include/boost/thread/pthread/shared_mutex.hpp:66: undefined reference to `boost::this_thread::disable_interruption::~disable_interruption()'/tmp/ccnnkCEQ.o: In function `~thread_data':/boost_1_45_0v/include/boost/thread/detail/thread.hpp:42: undefined reference to `boost::detail::thread_data_base::~thread_data_base()'/boost_1_45_0v/include/boost/thread/detail/thread.hpp:42: undefined reference to `boost::detail::thread_data_base::~thread_data_base()'/tmp/ccnnkCEQ.o: In function `thread, boost::_bi::list1lab1::Server* > > >':/boost_1_45_0v/include/boost/thread/detail/thread.hpp:204: undefined reference to `boost::thread::start_thread()'/tmp/ccnnkCEQ.o: In function `~auto_ptr':/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../include/c++/4.1.2/memory:259: undefined reference to `boost::thread::~thread()'/tmp/ccnnkCEQ.o: In function `~thread_group':/boost_1_45_0v/include/boost/thread/detail/thread_group.hpp:34: undefined reference to `boost::thread::~thread()'/tmp/ccnnkCEQ.o: In function `boost::thread_group::join_all()':/boost_1_45_0v/include/boost/thread/detail/thread_group.hpp:74: undefined reference to `boost::thread::join()'/tmp/ccnnkCEQ.o:(.rodata._ZTIN5boost6detail11thread_dataINS_3_bi6bind_tIvNS_4_mfi3mf0IvN4lab16ServerEEENS2_5list1INS2_5valueIPS7_EEEEEEEE[typeinfo for boost::detail::thread_data, boost::_bi::list1lab1::Server* > > >]+0x10): undefined reference to `typeinfo for boost::detail::thread_data_base'collect2: ld returned 1 exit statusmake: *** [lab2_server] Error 1 Date: Tue, 6 Sep 2011 02:50:50 +0400 From: i.nixman@gmail.com To: boost-users@lists.boost.org Subject: Re: [Boost-users] boost bind() error for creating thread threadGroup.create_thread(boost::bind(&lab1::Server::Run, &server)); 2011/9/6 Jack Bryan Hi, I using boost::bind() to create thread.
