#include <string> causes lots of '<blank>' has not been declared errors

Question

I'm trying to compile my 'graphics' engine, but am having a problem after including <string> (Debian Testing 64bit).

Here's the error:

jarrett@jarrett-g74s:~/projects/icebreak/ice_engine$ scons

scons: *** [build/engine/gui/GUI.o] Error 1
scons: building terminated because of errors.

The GUI.h is:

#ifndef GUI_H_
#define GUI_H_

#include <string>

#include "IGUI.h"

namespace icee {

namespace engine {

class GUI : public IGUI {
public:
    GUI();
    virtual ~GUI();

    virtual int initialize();
    virtual void destroy();

    virtual void render();
    virtual IGUIComponent* load(std::string filename);
};

}

}

#endif /* GUI_H_ */

and GUI.cpp is:

namespace icee {

namespace engine {

#include <berkelium/Berkelium.hpp>

#include "GUI.h"

GUI::GUI() {

}

GUI::~GUI() {

}

int GUI::initialize() {
    if (!Berkelium::init(Berkelium::FileString::empty())) {
        return -1;
    }

    return 0;
}

void GUI::destroy() {

}

void GUI::render() {

}

GUIComponent* GUI::load(std::string filename) {

}

}

}

and IGUI.h looks like this:

#ifndef IGUI_H_
#define IGUI_H_

#include <string>

#include "IGUIComponent.h"

namespace icee {

namespace engine {

class IGUI {
public:
    IGUI();
    virtual ~IGUI();

    virtual int initialize() = 0;
    virtual void destroy() = 0;

    virtual void render() = 0;
    virtual IGUIComponent* load(std::string filename) = 0;
};

}

}

#endif /* IGUI_H_ */

So far I'm kind of stumped. I tried to install build-essentials, but it was already installed. After some googling it seemed like the issue was that there was some missing dependencies somewhere, but I don't know where...

Anyone have any ideas?

Cheers

Answer 1

Your problem is where the includes are:

namespace icee {

namespace engine {

#include <berkelium/Berkelium.hpp>

#include "GUI.h"

move them outside of the namespace.
