Re: [Boost-users] The callback of the timer inside a thread is not called

it worked! Thank you so much Igor. I changed it this way: int main(int argc, char* argv[]) {    boost::asio::io_service::work work(io_service);    boost::thread thrd_io(boost::bind(&boost::asio::io_service::run, &io_service));    boost::thread workerThread(workerFunc); ... }

Can I ask why we needed io_service::work? in windows, it did not require it.

It's not a matter of platform, it's just a timing. You had a race condition, which produced different results under different circumstances.
