The following code piece does not compile for me:
#include <iostream>
#include <boost/thread.hpp>
int main(int argc, char* argv[])
{
boost::thread thread(
[]() {
std::cout<<"hello";
}
);
}
With the error :
no matching function for call to ‘boost::thread::thread(main(int, char**)::<lambda()>)’
I feel like I am making a very stupid mistake here, but it has been sometime, and i still fail to find it.
You need to capture io_service
by reference to get the above code snippet to compile:
void start_thread(boost::asio::io_service &io_service)
{
boost::thread tcp_thread(
[&io_service]() { // <-- you missed a & here
io_service.run();
}
);
}
Note that the io_service
does not implement copy semantics.
