Jared, std::bind1st was not meant to "freeze" operations, but just for simple currying scenarios. As such, it expects a binary function as input. For a more generic binder, use boost::bind. In fact, just replace std::bind1st with boost::bind (and, yes, you can then skip that mem_fun altogether) and include <boost/bind.hpp>. I.e., your problem had nothing to do with boost::function.

I'm sure I'm missing something pretty fundamental here. I'm trying to set a boost::function to a member function without any parameters. The following code fails to build (using VS 2005, haven't tested anything else). If I set it to a non-member function it works fine.

#include <functional> #include <boost/function.hpp>

class test { public: int GetInt() { return 1; } };

int _tmain(int argc, _TCHAR* argv[]) { test inst; boost::function<int ()> getter;

// Getting several errors where it appears that <int ()> isn't being handled // as a signature when being handled by mem_fun. Not sure whether that is related. getter = std::bind1st( std::mem_fun(&test::GetInt), &inst);
