编译现有代码库时出现编译错误

Question

在Mac OS上使用原生构建设置构建现有代码时，我在编译阶段遇到了一些基本的奇怪错误。

你们有没有什么想法，因为我已经看到，它也在这个论坛之前讨论过，没有任何好的理由。我看不到包含任何冲突的文件。但是我仍然无法编译代码，因为出现了这个错误。

源代码类似于下面给出的代码，并出现编译错误

$ cat a.h
    #include <string>
    #include <sstream>

    namespace brijesh {
        typedef std::string String;

        template<class T>
        String toString(T value) {
            std::ostringstream buffer;
            buffer << value;
            return buffer.str();
    }

$ cat b.h
    #include "a.h"
    namespace brijesh {
        class Platform {
            public:
                static String getName();
        };
     }

$ cat b.cpp
     #include "b.h"

     namespace brijesh {

         String Platform::getName()
         {
             String  name = "UNKNOWN";
     #ifdef  LINUX
              name = "linux";
     #endif
     #ifdef  MACOSX
              name = "Mac";
     #endif
              return name;
         }
     }

用于编译的标志

看起来您正在尝试使用OSX10.3开发人员工具(Xcode等人)，并试图以OSX10.4为目标，这显然是行不通的。或者更改您的构建命令以删除不兼容的标志，例如-mmacosx-version-min=10.4，或者升级到更新版本的OS X+ Xcode +SDK。
