无法编译项目:locale.h文件中的错误

Question

我正在尝试编译一个具有以下标题的项目:locale.h;

locale.h文件:

class LOG4CXX_EXPORT Locale
{
public:
       ...

protected:
    Locale(const Locale&);
    Locale& operator=(const Locale&);
    const LogString language; <-- error
    const LogString country;  <-- error
    const LogString variant;  <-- error
}; // class Locale

有人能给我一些建议吗？

我收到了这个错误.我不确定是什么问题.

/LOGGER/include/log4cxx/helpers/locale.h:42:41: error: field ‘language’ has incomplete type
                     const LogString language;
                                     ^
/LOGGER/include/log4cxx/helpers/locale.h:43:41: error: field ‘country’ has incomplete type
                     const LogString country;
                                     ^
/LOGGER/include/log4cxx/helpers/locale.h:44:41: error: field ‘variant’ has incomplete type

您正在使用 std::basic_string，但没有包含相应的头文件：

#include <string>
