Hi! This is most probably a "newbie question", but I really don't see what exactly wrong I'm doing, so will appreciate any inputs. Basically, what I'm trying to do is: using namespace boost::posix_time; using namespace boost::this_thread; time_duration td = milliseconds(2000); sleep(&td); And it works ok with Visual Studio and Windows. Once I get it to linux and try to compile with gcc, this is what I get: g++ -c -Wall -I/home/gsed/boost/ main.cpp -o main.o In file included from /home/gsed/boost/boost/thread/thread.hpp:17:0, from includes.h:12, from main.cpp:1: /home/gsed/boost/boost/thread/pthread/thread_data.hpp: In function void boost::this_thread::sleep(const TimeDuration&) [with TimeDuration = boost::posix_time::time_duration*]: main.cpp:47:11: instantiated from here /home/gsed/boost/boost/thread/pthread/thread_data.hpp:138:13: error: no match for operator+ in boost::get_system_time() + rel_time /home/gsed/boost/boost/date_time/time.hpp:139:15: note: candidates are: time_type boost::date_time::base_time<T, time_system>::operator+(boost::date_time::base_time<T, time_system>::date_duration_type&) const [with T = boost::posix_time::ptime, time_system = boost::date_time::counted_time_system<boost::date_time::counted_time_rep<boost::posix_time::millisec_posix_time_system_config>

ie it's trying to perform a boost::posix_time::ptime + time_duration operation, but for some reason can't decide between operator+(boost::date_time::base_time<T, time_system>::date_duration_type&) and operator+(boost::date_time::base_time<T, time_system>::time_duration_type&) And I'm absolutely not sure why. Win version works well I guess because there's another include file used and the whole thing is arranged differently. Again, any inputs or advice are greatly appreciated. Thanks! -- Take care, Alexey Malakhov
