静态插入时有关stl Map核心的信息

问题描述

dll.cpp:

#include <stdio.h>

#ifdef __cplusplus
extern "C" {
#endif

void show(){
    fprintf(stdout,"%s","dll show call.");
}

#ifdef __cplusplus
}
#endif

dll_1.cpp:

dll_1.cpp:

#include "dll.h"

map<string,value> g_map;

int register_funk(string xx,fn_cmd_handler_t fn, string dex) { // removed obscenity
    fprintf(stdout,"%s","core begin\n");
    fprintf(stdout,"%u",g_map.size());
    fprintf(stdout,"%s","core end\n");
    fprintf(stdout,"-------fn-%p",fn);
    fprintf(stdout,"%s","----\n");
    fprintf(stdout,"%s","----\n");
    g_map[xx].fn = fn; //---------->core at this, why ?? who can tell me????
    g_map[xx].des = dex;
    return 0;
}

dll_2.cpp:

dll_2.cpp:

#include "dll.h"

int samxxxx( int machine_id, vector<string> &vecValue );

static int __inss = register_funk("xxxx",samxxxx,"funk"); // removed obscenity

int samxxxx( int machine_id, vector<string> &vecValue )
{
    fprintf(stdout,"%s","ssss--------->");
    return 0;
}

dll.h:

dll.h:

#ifndef __xxxx__
#define __xxxx__

#include ,map>
#include <vector>
#include <string>
#include <stdio.h>
using namespace std;
typedef int ( *fn_cmd_handler_t )( int machine_id, vector<string> &vecValue );

typedef struct {
    fn_cmd_handler_t fn;
    string des;
}VALUE;


int register_funk(string xx,fn_cmd_handler_t fn, string dex);  // removed obscenity

#endif

//我建立了这个，所以使用
//g ++ -g -O2 -shared -Wall -o a.so * .cpp

//以下是exe文件

//and i build this so use
//g++ -g -O2 -shared -Wall -o a.so *.cpp

//the follow is exe file

//main.cpp
#include <dlfcn.h>
#include <stdio.h>

int main()
{
    void *handle = dlopen("/home/samuel/Temp/funk/a.so", RTLD_LAZY);
    fprintf(stdout, "%s\n", dlerror());
    dlclose(handle);
    return 0;
}

//i建立此用途
//g ++ main.cpp -rdynamic -ldl
当我在centos中键入此内容时
> ./a.out
它核心
谁能告诉我为什么?
非常感谢:)

//i build this use
//g++ main.cpp -rdynamic -ldl
when i type this in centos
>./a.out
it core
who can tell me why?
thanks a lot :)

推荐答案

#include "OtherClass1.h"
#include "OtherClass2.h"

class OtherClass3;

class CDll
{
public:
   CDll();
   ~CDll();
   void func();
   void func2();

private:
   std::map<x,y> m_Map;
   int m_BlahBlah;
   int m_XXX;
   OtherClass1 m_OtherClass1;
   OtherClass2 m_OtherClass2;
   OtherClass3* m_OtehrClass3;
};

// The only static variable in the DLL
CDll g_Dll;


// functions exported by the shared lib:
void shared_dll_func()
{
   g_Dll.func();
}

void shared_dll_func2()
{
   g_Dll.func2();
}
