While I've successfully used boost::bind before, I cannot seem to get this
simple test case to work.
#include <boost/bind.hpp>
#include <iostream>
using namespace boost;
using namespace std;
struct X
{
void f( int i )
{
cout << i << "\n";
}
};
int main( int argc, char * argv[] )
{
X x;
bind( &X::f, &x, 6 )(); // works
bind( &X::f, &x, _1 )( 6 ); // error!
return 0;
}
It fails during compilation with the following error messages:
callback.cpp: In function `int main (int, char **)':
callback.cpp:20: no match for call to `(boost::_bi::bind_t<void,
boost::_mfi::mf1<void, X, int>, boost::_bi::list2<boost::_bi::value<X

Suggestions?
