I'm trying to use bind with boost.thread in order to make a thread of a class member function with an input argument, but I can't get it to compile. To narrow the problem, I went to the bounded_buffer.cpp program in the libs/thread/tutorial dir. I added an int arg to sender, and then changed boost::thread thrd1(&sender); to int x = 99; boost::thread thrd1(boost::bind<void>(&sender, _1)(x)); and several other combinations including removal of <void>. In the above case, gcc results in /mnt/shared/Projects/boosttest/src/bounded_buffer.cpp:77: error: call of overloaded `bind(void (*)(int), boost::arg<1>&)' is ambiguous /usr/include/boost/bind.hpp:1132: note: candidates are: boost::_bi::bind_t<R, F, typename boost::_bi::list_av_1<A1>::type> boost::bind(F, A1) [with R = void, F = void (*)(int), A1 = boost::arg<1>] I got this syntax from the bind doc (http://www.boost.org/libs/bind/bind.html). What am I doing wrong? thanks, Jason
