Initialize structure with shared_ptr <void>

Question

I constantly encounter an error that makes sense no matching constructor for initialization of 'std::shared_ptr<void>', but I don’t know where to start.

Here is what I work for.

#include <memory>                                                                                                                                                             

struct Container {                                                             
  int type;                                                                    
  std::shared_ptr<void> payload;                                               

  Container(int t, const void *p) : type(t), payload(p) { }                    
};                                                                             

int main() {                                                                   
  return 0;                                                                    
}

I am trying to create a generic container using shared_ptrwith a type void. I was going to make a type switch, and then just pass the payload to the appropriate type.

I decided that I could just do something like Container ctn(1, new Data());that, but I think I might have it wrong too.

Thank.
