编译错误C3861 Visual Studio 2010

Question

我收到两个错误，无法弄清楚我的生活... 我在过去的几个小时在谷歌研究它。我现在正在哪里。 这是我收到的编译错误。

2 IntelliSense: identifier "RegisterShader" is undefined c:\users\administrator\documents\visual studio 2010\projects\test\dllmain.cpp 18 20 

Error 1 error C3861: 'RegisterShader': identifier not found c:\users\administrator\documents\visual studio 2010\projects\test\dllmain.cpp 50 1

几种方法可以做到这一点：

dllmain.cpp

#include "stdafx.h" 
#include "typedefs.h" 

extern tRegisterShader RegisterShader; 

剩下的是你已经拥有它。

typedefs.h

#ifndef TYPEDEFS_H 
#define TYPEDEFS_H 

#define OFF_REGISTERSHADER 0x00715690 

typedef float vec_t; 
typedef vec_t vec2_t[2]; 
typedef vec_t vec3_t[3]; 
typedef vec_t vec4_t[4]; 
typedef int qhandle_t; 

typedef int (* tRegisterShader)(char* szName, int unk); 

extern tRegisterShader RegisterShader; 

#endif

或者，您也可以通过将在EXTERN的typedefs.h底部的 “发布” 在typedefs.cpp定义的变量后一种方法在发布头文件中定义的类型的全局变量时很常见，其中变量在匹配的.cpp文件中定义。在头文件中声明它为extern有效地将它公开给任何人，包括头文件（包括你的dllmain.cpp）。
