I am using Dev-C++ 4.9.8.0 and lambda expression.
I builded a class and put it into a dll made by myself.
The dll will be used by else's programs which contain the functions that I do not know. All I know is just the function type.So I used the boost function library.
............
class classA{
.................
public:
boost::function theunknownfunc;
........................
and a member function in classA used such function:
double classA::function1( int& q, const int& n){
double result=0.0;
int loopvalue=1, totaltime=thenumbern;
int innern=1;
( for_loop(var(loopvalue)=1,var(loopvalue)<=var(totaltime),++var(loopvalue),
(var(result)+=
( bind(&classA::theunknownfunc,this,_2)*bind(&classA::function2,this,_1,_2)),
++_2,_2%=_1)))
(q,innern);
return result;
}
.................
but the complier told me that:
instantiated from `RET boost::lambda::lambda_functor_base::call(A&, B&, C&, Env&) const [with RET = void, A = int, B = int, C = const boost::tuples::null_type,<.............
instantiated from `T::sig
