You need to build the thread library. See http://www.boost.org/more/getting_started/unix-variants.html If you've already compiled the library, try -lboost_thread. If you didn't install the libraries to a system location, then you'll also need -L/path/to/compiled/libraries

int main() { boost::thread myThread(threadFun); // Create a thread that starts // running threadFun boost::thread::yield(); // give up the main thread's timeslice // so the child thread can get some work // done.

// Go do some other work...

myThread.join(); // The current (i.e., main) thread will wait // for myThread to finish before it returns }

I think you are not linking pthread. you need to link both ( -lpthread -lboost_thread ). g++ -static -I(Path to boost include) -L(path to boost library) yourfile.cpp -lboost_thread -lpthread -o yourOutputExe.out (plz ignore any typo). Thanks. Kaz On Tue, May 24, 2011 at 6:15 AM, Eric Lin wrote:
