我正在尝试编译我的“图形”引擎，但在包含 <string> 后遇到问题(Debian 测试 64 位)。
这是错误:

GUI.h是:
#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_ */
和GUI.cpp是:
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) {
}
}
}
和IGUI.h看起来像这样:
#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_ */
到目前为止，我有点难过。我尝试安装 build-essentials，但它已经安装好了。经过一些谷歌搜索后，问题似乎是某处缺少一些依赖项，但我不知道在哪里......
有人有什么想法吗？
干杯
最佳答案
您的问题是哪里包含:
namespace icee {
namespace engine {
#include <berkelium/Berkelium.hpp>
#include "GUI.h"
将它们移出命名空间。
