did you find a solution for this compilation errror ? regards Clark Sims-2 wrote:

I can compile the following code fine in boost 1.33.1 but it generates compiler errors in version 1.39. I am using visual studio 2005.

I will post the code, and then post the compiler errors:

#include <iostream> #include <boost/thread/thread.hpp> #include <boost/thread/xtime.hpp> #include <boost/thread/recursive_mutex.hpp>

using namespace std; //using namespace boost; using boost::mutex; using boost::thread; using boost::recursive_timed_mutex; using boost::xtime;

boost::recursive_timed_mutex hello_mutex;

void hello( int thread_id, int iter) { cerr << thread_id << " : " << iter << endl; }

void rand_xtime( xtime* xt) { xtime_get( xt, boost::TIME_UTC); //xt.nsec += (rand() % 1000000000); xt->sec += 1 + rand()%5; }

void say_hello( int thread_id) { for (int iter=0; iter<5; iter++) { xtime xt; rand_xtime( &xt); thread::sleep(xt); rand_xtime( &xt); { recursive_timed_mutex &refer_hello = hello_mutex; const xtime& refer_xt = xt; recursive_timed_mutex::scoped_timed_lock lock1( refer_hello, refer_xt); if (lock1) { hello( thread_id, iter); } } } }

void hello1() { say_hello( 1); }

void hello2() { say_hello( 2); }

int main() { boost::thread thrd1(hello1); boost::thread thrd2(hello2);

thrd1.join(); thrd2.join();

return 0; }
