有一个在我的代码编译错误 '*'(还没有找到解决方案)之前:错误C2143:语法错误:缺少';'
#include <iostream>
#include <vector>
#include "command.h"
extern std::istream *instream;
extern std::vector<command> commands;
这里是command.h头文件:
#define CMD_RETURN_TYPE_NONE 0
#define CMD_RETURN_TYPE_STRING 1
#define CMD_RETURN_TYPE_CHAR 2
#define CMD_RETURN_TYPE_INT 3
class command {
public:
virtual int getReturnType(void);
virtual char getOpName(void);
virtual void* call(void);
}
抛出下一个编译错误

我还没有找到解决方案,该如何解决?
什么是'command'? 'command.h'分别。 –
@πάνταῥεῖ是啊,command.h,这是抽象类 –
请[edit](http://stackoverflow.com/posts/34653404/edit)你的问题添加这样的信息。 –
