Re: [boost] using lambda's pointer to member function and, boost::function

try boost::lambda::bind(&aux::a, _1, x);

Thanks for your advice, but that's not the kind of solution that I'm looking for. There are some constraints on aux that forbids me to use bind. Please read the thread http://lists.boost.org/boost-users/2006/11/23754.php where I explain the whole situation. Thanks, Rodolfo Lima.
