Hi, I have problems with the attached code (test.cpp, extracted from the original class only with the relevant code). The member template constructor of CCycleThread takes an argument and passes this to boost bind. The binding is to a another member template method which is the thread function for boost thread: boost::thread(boost::bind(&CCycleThread::execute<T>,this,t) The template parameter type is deduced by the argument type passed by the user. If the type is an ordinary function the code works fine. If the argument itself is another boost bind object the compilation fails! I tested the following within the constructor: auto test = boost::bind(&CCycleThread::execute<T>,this,t) // -> ok test(); // -> compile error The call of the operator() of the bind object is the problem. Interestingly, if one binding is boost::bind and the other one is std::bind the code works. Any ideas what's the problem? How can I fix this? Using std and boost bind is more a hack than a real solution :/
