错误：expected constructor, destructor, or type conversion before ‘typedef’ 的解决方法

错误现象：

/*交易指令结构体*/
class TradeData {

public:

CT_STRUCT value;

TradeData(CT_STRUCT * _value)
{
memset(&value,0,sizeof(value));
memcpy(&value,_value,sizeof(value));

{
memset(&value,0,sizeof(value));
}

//序列化对象
std::string serialize();

//把字符串解释称结构体
bool TradeData::unserialize(std::string str);

};

#endif

原因：config.h里面的USING_PTYPES 没包含ptypes头文件所致。
