我有一个这样的全局结构：-
struct MachineList
{
BSTR AccountId;
BSTR MachineId;
BSTR Make;
char* Make1;
BSTR Model;
char* Model1;
BSTR SerialNumber;
BSTR IpAddress1;
char* IpAddress;
BSTR Port1;
int Port;
BSTR LocationCode;
SOCKET Sock;
BSTR Status;
} MACHINELIST,*PMACHINELIST;
int MachineCount=-1;
我有一个 XML，我对其进行解析并将其存储在如下结构中：- 我想将通过解析填充的每个结构添加到 stl 列表中，因此我添加了以下代码
vector<struct MACHINELIST > SS;
现在我收到以下错误：-
错误 C2371：'MACHINELIST'：重新定义；不同的基本类型错误 C2512：'MACHINELIST'：没有适当的默认构造函数可用
