Hello,
a number of platforms currently fail to compile these tests with an error message similar to the following:
cxx: Error: ../boost/thread/pthread/thread.hpp, line 169: more than one instance of overloaded function "boost::bind" matches the argument list: (ambovlfun) function template "boost::bind<R,F,A1>(F, A1)" function template "boost::bind(R (T::*)(), A1)"
The code in question reads:
template <class F,class A1> thread(F f,A1 a1): thread_info(make_thread_info(boost::bind<void>(f,a1))) { start_thread(); }
The best fix here is probably
boost::bind( boost::type<void>(), f, a1 )
This fails (CXX 7.1 on Tru64) with: cxx: Error: ../../../boost/mem_fn.hpp, line 342: a pointer to a bound function may only be used to call the function (boundfuncalled) detected during: instantiation of "R &boost::_mfi::dm<R, T>::operator()(T *) const followed by a few 100 lines of error context.
1) make_thread_info(boost::bind(f,a1))
This will fail when f is a function object without a result_type typedef.
2) make_thread_info(boost::bind<void>(mem_fn(f),a1))
This will fail when f is not a member pointer.
It seems that these will be exposed by test_thread_launching. It only misses the cases "ordinary function with arguments" and "member pointer".
The alternative syntax should work in all cases; can you please test it?
See above for results. Do you consider it to be a compiler problem? Hmm, maybe modifying the tests to use boost::thread t(mem_fn(&this_type::locking_thread),this) would be the easiest way out? Markus
