Hi All, I came across this strange error. Binding of overloaded member
functions works with boost bind, but not with boost lambda bind. Here
is the example
Following builds and works fine
#include "boost/function.hpp"
#include "boost/bind.hpp"
class Operations
{
public:
void Fun1( int i ){ std::cout<<"\nfunction with one arg\n"; }
void Fun1( int i, double d) {std::cout<<"\nfunction with two args\n"; }
};
-----------------------
int main()
{
Operations op;
typedef boost::function fptr;
fptr func1 = boost::bind( &Operations::Fun1, &op,1);
fptr func2 = boost::bind( &Operations::Fun1, &op, 1, 2.2 );
return 0;
}
------------------------
While following Does not compile
int main()
{
using namespace boost::lambda;
Operations op;
typedef boost::function fptr;
fptr func1 = bind( &Operations::Fun1, &op,1);
fptr func2 = bind( &Operations::Fun1, &op, 1, 2.2 );
return 0
}
-------------------------
This spits out massive error, as shown below. I think gist of which is
it can't figure out which function to instantiate, when using lambda
bind. Can some body please point out what am I missing here ?
(Sorry for long email, I didn't wanted to clutter the email with this
error message, bu thought most of you will figure it out just from
looking at it.).
Any help will be appreciated, and thanks in advance.
