Question

EDIT: aList was being referenced as a pointer in this version of my code, but not in my current version which still has the same problem.

I had this code perfectly working before trying to split it in an interface file and an implementation file. But when I splitted it, the compiler tells me I’m calling push_back() with incorrect parameters. So I understand it cannot reference the type of the object I’m pushing it, although it’s the same (afaik, of course :D).

#ifndef _MYHEADER_HPP_
#define _MYHEADER_HPP_
class A{
public:
    std::string someString;
};

class B{
public:
    std::vector<A> aList;
public:
    void addA();
};

#endif /* _MYHEADER_HPP_ */

//implementation file

#include <string>
#include <vector>
#include "myheader.hpp"

void B::addA(){
    A a;
    a.someString = "Hola";
    // Here compiler says : Invalid arguments 'Candidates are: void push_back(const A &)' line 18 Semantic Error
    aList.push_back(a);
}

AFAIK, std::vector always do a copy of the object to push, and that copy gets stored into the vector, so I think it’s not a problem of ‘a’ being stack allocated, am I right?

What I’m doing wrong?
Thanks.

Ok, after more than 3 hours looking for the root of the problem, I found that Eclipse CDT IDE had a corrupted cache file about my code. So, compiling from command line was everything fine, I had to delete that cache file and then Eclipse reported no errors.
