我正在尝试将 jsoncpp 集成到一个项目中。我的平台是 32 位 xubuntu，gcc 版本为 4.7.2。我尝试使用 debian 包，也是从最新的 jsoncpp 源构建的，两者都导致相同的问题。

我使用 CMake 进行构建。已成功找到 jsoncpp 包含和库。但是当我将包含添加到我的 CMake 包含时，我的空 brConfig 类（在第 51 行中只有一个 #include）的构建失败并出现以下错误：

在我看来，这个问题是由 std::string 包含调用的。知道出了什么问题吗？

这是我的简单课程：

#ifndef BINREV_CONFIG_H__
#define BINREV_CONFIG_H__

#include <string>      // compile fails here if I add JSON includes to CMAKE

namespace binrev{
namespace brCore{

class CORE_LIBRARY_API brConfig
{
   public: 
     brConfig();     
     virtual ~brConfig();

};
}//ns-brCore
}//ns-binrev
#endif //BINREV_CONFIG_H__
