<功能列表>多重定义

Question

我敢肯定，答案是直视我的脸，但由于这个原因，我还没有能够取得任何进展......首先一些代码：

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... 

当我编译THI S码，我得到以下错误：

我已经试过以下是解决：

• 结合头和cpp文件。
• 清空所有的方法体并删除#includes以便所有重要的是类结构。
• 谷歌搜索（没有任何运气...）

感谢您的帮助！

我从mingw32（www.mingw.org）使用gcc4.8.1编译你的代码（把它们放到文件中，并替换丢失的类型）。汇编似乎是确定的。我想这个问题可能是

#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() {}
