I've been trying to track down what the maximum number of arguments that can be added to boost::function<> is. I'm starting to believe that the maximum number is 10 arguments. As it seems that when I input 11 arguments VS complains with this error: Error 1 error C2079: 'my_func' uses undefined class
'boost::function<Signature>' Error 2 error C2440: 'initializing' : cannot convert from 'void (__cdecl *)(const char *,affine_transformation_range *,int,int,double,int,int,int,int,int,char)' to 'int'
My declaration looks like as follows:
function

That sounds right. You can increase the limit by
#define BOOST_FUNCTION_MAX_ARGS 20
#include

The absolute limit without modifying boost/function/detail/maybe_include.hpp is 50 arguments.

Steve, thanks so much for that trick! It worked like a charm. -- Ryan Lovelett Ryan.Lovelett@gmail.com (352) 286-8637

So now I've hit the next logical error in this that, I believe is a related issue. boost::bind() only allows for 10 arguments, so I assume I'm going to either have to specify a processor that allows bind to take 20 arguments. Or am going to have to extend bind to allow it to take more? Any help pointing me in the right direction would be greatly appreciated. -- Ryan Lovelett Ryan.Lovelett@gmail.com

For bind, there is no PP symbol which can adjust the limit. Take a look at the header boost/bind.hpp. Everything is written out explicitly. In Christ, Steven Watanabe
