将C ++代码从VS迁移到Xcode

Question

我的代码在Visual Studio和Windows中运行良好，但在Xcode中我遇到了很多问题。首先，我想知道在我删除direct.h include（在Xcode，mac中）后，我收到以下错误

此外，我创建的类中的对象（这与direct.h无关）都无法初始化。 Xcode似乎不理解我的任何构造函数。错误消息如下所示。该示例适用于我的一个对象。有任何帮助吗？

这是我的一个课程。请注意，并非所有课程都没有加载!!

Answer 1

我找到了从https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man3/getcwd.3.html处理Xcode中的getwcd的方法。该解决方案类似于@Cyber​​建议的解决方案。我必须在头文件中进行以下更改;

//#include <direct.h> // for _getcwd WIN
#include <unistd.h> // for getcwd Mac

并使用

getcwd()

而不是

_getcwd() 

在我的功能中

void GetCurrentPath(char* buffer){getcwd(buffer,PATH_MAX);}

然后在我的函数main（）中使用了

//Curent path
    char current_path[PATH_MAX]; //CurrentPath[_MAX_PATH]; windows
    GetCurrentPath(current_path);
    cout << current_path << endl;

通过查看头文件解决了我的问题的第二部分。我曾使用Xcode创建空头文件hbv.h然后我错误地粘贴了我在#endif下面而不是#endif以上的VC ++中使用的旧版hbv.h文件中的代码

    #ifndef hbvOptimMAC_hbv_h
    #define hbvOptimMAC_hbv_h
    //<code defining classes was correctly pasted here>
    #endif
    //<code defining classes initially mistakenly pasted here>
