[SOLVED] new to c++, two errors while compiling headers

[Manuel Di Criscito]

Hi, i am new to c++, i am using code::blocks.
I was using Lazarus for object-pascal programming with a good knowledge but now i decided to learn c++, adding a challenge to my programming way.

Trying to port my .pas game to .cpp using SDL2 game engine.

header.h

class CTexture
{
public:
  SDL_Texture Load( string Dir );
}

header.cpp

SDL_Texture CTexture::Load( string Dir )
{
  ...
  // This function will load texture from disk ( i know how to do it, my problem is other)
  ...
}

Errors found:

In header.h

error: 'string' has not been declared
error: candidate is: SDL_Texture CTexture::Load(int)

In header.cpp

error: prototype for 'SDL_Texture CTexture::Load(std::string)' does not match any in class 'CTexture'

So.. what should i do!?
Please, help.
Thanks

Have you #included the header file required for the string class and how are you scoping the items in the std:: namespace?

[Manuel Di Criscito]

In header.h

#ifndef HEADER_H_INCLUDED
#define HEADER_H_INCLUDED
#include "SDL.h"
#include "SDL_image.h"
#include <iostream>
#include <string>
#include <windows.h> 

In header.cpp

#include <iostream>
#include <string>
#include <windows.h>
#include "header.h"
#include "SDL.h"
#include "SDL_image.h"

using namespace std;

Hnm.. What is std:: namespace..?
Help

It is the namespace where all the standard C++ classes are defined. In your header you will need to properly scope these items.

header.h from above:

class CTexture
{
public:
  SDL_Texture Load( std::string Dir ); // Note the proper scoping for the std::string class.
}

Thanks.. but new error appeared on header.cpp

error: return type 'SDL_Texture { aka struct SDL_Texture}' is incomplete

Why?

I just saw this post a bit before you answered me.. it now works! Thanks!
