Question

我确信答案是直截了当地盯着我，但由于这个原因我无法取得任何进展......首先是一些代码：

对象/ testObject.h：

#include <irrlicht.h>
#include "../maths.h"

using namespace irr;

#ifndef testObject_H
#define testObject_H

class testObject : public scene::SAnimatedMesh
{
    public:
        testObject(IrrlichtDevice* device);
        virtual ~testObject();
    protected:
        const char* meshInfoLocation;
        int totAnims;
    private:

};

#endif

对象/ testObject.cpp：

#include "testObject.h"

testObject::testObject(IrrlichtDevice* device) : scene::SAnimatedMesh()
{
    io::IrrXMLReader* modelInformation = io::createIrrXMLReader(meshInfoLocation);

    while(modelInformation->read())
    {
        if(modelInformation->getNodeName() == "totAnims") totAnims = stringToInt(modelInformation->getAttributeValue("totAnims"));
    }
}

testObject::~testObject() { } //Incomplete, but should still compile...

编译此代码时，出现以下错误：

我在解决时尝试了以下方法：

合并标头和cpp文件。
清空所有方法体并删除#includes，以便重要的是类结构。
谷歌搜索（没有任何运气......）

感谢您的帮助！

我使用mingw32（www.mingw.org）中的gcc4.8.1编译代码（将它们放入文件中，并替换丢失的类型）。编译似乎没问题。我想问题可能是

#include <irrlicht.h>
#include "../maths.h"

代码：

//#include <irrlicht.h>
//#include "../maths.h"

//using namespace irr;

#ifndef testObject_H
#define testObject_H
#include <tuple>
namespace scene {
  typedef  std::tuple<int,int> SAnimatedMesh;
};
typedef int IrrlichtDevice;

class testObject : public scene::SAnimatedMesh
{
    public:
        testObject(IrrlichtDevice* device);
        virtual ~testObject();
    protected:
        const char* meshInfoLocation;
        int totAnims;
    private:

};

#endif

//#include "testObject.h"

testObject::testObject(IrrlichtDevice* device) : scene::SAnimatedMesh()
{
  /*
    io::IrrXMLReader* modelInformation = io::createIrrXMLReader(meshInfoLocation);

    while(modelInformation->read())
    {
        if(modelInformation->getNodeName() == "totAnims") totAnims = stringToInt(modelInformation->getAttributeValue("totAnims"));
    }
  */
}

testObject::~testObject() { } //Incomplete, but should still compile...

int main() {}

<list of =“”functions =“”> </list>的多重定义
