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__
