各位牛人，小弟有一事不明，给分100
我在appprot.h 中定义如下
#ifndef APPPROT_H
#define APPRPOT_H
struct app_solo_head
{
char app_state_flag;
char app_data_type;
int len;
char app_serve_type;
char node_type;
}；
#define APPHEADBUF_SIZE sizeof(app_solo_head)
extern app_solo_head *apphead;
extern char appheadBUF[APPHEADBUF_SIZE];
#endif
我在appprot.cpp 中定义如下
#include "stdafx.h "
#include "appprot.h "
struct app_solo_head *apphead;
char appheadBUF[APPHEADBUF_SIZE];
apphead = (struct app_solo_head *)( &appheadBUF[0] );
然后我编译了一下，出现如下三个错误，请大虾帮忙;
Compiling...

[解决办法]
apphead = (struct app_solo_head *)( &appheadBUF[0] );不能放到全局空间中，应该放到函数中
[解决办法]
错误的根源就在于
apphead = (struct app_solo_head *)( &appheadBUF[0] );
这条语句. 不过倒不是它本身有什么错,而是你把它放错了地方: 它不能出现在全局定义中.
须知全局定义只能是declare(变量声明之类),而不能是这种statement语句
修改方法有两种:
1.把它放到main()或其它任何函数体中.
或者:
2. 将这三行:
struct app_solo_head *apphead;
char appheadBUF[APPHEADBUF_SIZE];
apphead = (struct app_solo_head *)( &appheadBUF[0] );
修改成:
char appheadBUF[APPHEADBUF_SIZE];
struct app_solo_head *apphead = (struct app_solo_head *)( &appheadBUF[0] );
