IMO boost::function doesn't supports move semantics. I will take a look at
std::function. Could you post the error with std::function?
code:
#define BOOST_THREAD_VERSION 4
#include
#include <functional>
int main()
{
boost::packaged_task t1;
std::function f2(boost::move(t1));
}
error:

I initially though behavior was different when using boost::move() and
std::move() to move t1 but boost::move actually is std::move on C++11
compiler. Hope this helps.
