高手们,这些未解决的外部变量我都有定义了啊,怎么还会不认呢?怎么解决啊?

不要乱引用你的头文件啊,主意包含和被包含关系,自己理理啊,问题不大

首先强调一点，这些不是compile error,
而是 link error.

是你缺少包含相应的lib文件

GoldenFall

#include "stdafx.h"加在.cpp文件的开始.

too strange.
Can type chinese?
Add follow codes to your *.cpp.
then the first lnk can be cleared.
the last two lnk i can't test, you need to try yourself.


extern "C" __declspec(dllimport)
BOOL KernelIoControl(
                                         DWORD dwIoControlCode,
                                         LPVOID lpInBuf,
                                         DWORD nInBufSize,
                                         LPVOID lpOutBuf,
                                         DWORD nOutBufSize,
                                         LPDWORD lpBytesReturned);

extern "C" __declspec(dllimport)
BOOL InterruptInitialize(
  DWORD idInt,
  HANDLE hEvent,
  LPVOID pvData,
  DWORD cbData
);

楼主在写驱动还是应用程序？
如果是驱动,你要把Coredll.lib Link进来，因为KernelIoControl和InterruptInitialize都在这个Lib中。
还有CEDDK.lib也要，READ_PORT_UCHAR和WRITE_PORT_UCHAR在这个Lib中。


如果应用程序，也可以像上面那样做。
但建议还是LoadLibray和GetProcAddress来加载。
KernelIoControl和InterruptInitialize在CoreDll.dll里，另两个不知道在哪个DLL里，你自己找找看。

把链接库的路径加上试试看
