Hello All, I am new to boost and hence i would like to ask a few questions on multi threading feature of this library. I am ataching a program can some one help to find out why i am getting this error as given follows Master.cpp: In member function `void master::Master::createt()': Master.cpp:17: error: no matching function for call to `boost::thread::thread(<unknown type>)' /opt/boost/include/boost-1_33_1/boost/thread/thread.hpp:35: note: candidates are: boost::thread::thread(const boost::thread&) /opt/boost/include/boost-1_33_1/boost/thread/thread.hpp:38: note: boost::thread::thread(const boost::function0<void, std::allocator<boost::function_base> >&) /opt/boost/include/boost-1_33_1/boost/thread/thread.hpp:37: note: boost::thread::thread() Thanks Abhishek
