C ++ .obj lnk1120和lnk2019

Question

所以我开始为我的c ++程序创建一个传递器而且我已经有一段时间出现这个错误了。在项目中包含.obj文件时出现了错误但是我刚刚将它删除了我还有这些错误。

我知道这只是我对象的传球者的开始，但它仍然不应该在.obj文件中出现错误，此时实际方法甚至不被调用

以下是错误：

error LNK1120: 1 unresolved externals \Debug\FP3DA   Framework.exe  FP3DA Framework

error LNK2019: unresolved external symbol "class GameObject __cdecl object(void)" (? object@@YA?AVGameObject@@XZ) referenced in function "public: class GameObject __thiscall passer::fileRead(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >)" (?fileRead@passer@@QAE?AVGameObject@@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z) passer.obj  FP3DA Framework

以下是目前不完整的传球手代码：

    #include "passer.h"
using namespace std;


GameObject passer::fileRead(std::string filename)
{
    GameObject object();
    string MaterialLib;
    char fileChar;
    // Open File
    ifstream File;
    File.open(filename.c_str());

    //Check open correctly
    if(!File.good())
        cerr << "Can't open file" << endl;


    //if open
    if(File)
    {
        fileChar = File.get();

        switch(fileChar){

        case 'm': //Material 'mtllib'
            fileChar = File.get();
            while(fileChar != ' ')
                fileChar = File.get();

            fileChar = File.get();

            break;

        case '#':
            fileChar = File.get(); // Next Character from #_
            fileChar = File.get(); // Next Character from #__
                if(File.get() != ' ')
                {
                    //name of object
                }
                else
    //                  File.getline; // Next Line


             break;

        case 'v':
            fileChar = File.get();

            //get vertices

            break;

        case 'vn':
            fileChar = File.get();

            //get vertex normal

            break;

        case 'vt':
            fileChar = File.get();

            //get vertex texture

            break;

        //   fileChar = File.getline;
             break;
        }


    } //file closed



    //READ MATERIAL FILE



    return object();


}//end of file reader method

    passer::passer(){}

    passer::~passer(){}
