完美编译运行PCRE on Windows , Solved the __imp__pcre_exec __imp__pcre_compile __imp__pcre_free Errors

写写英文吧，好长时间不写都有点不熟练了when I compile the following codes which test the pcre , I got the unreferenced error __imp__pcre_exec __imp__pcre_compile __imp__pcre_free Errors,my Codes are follows:

//packing pcre usual functions.

#ifndef _PCRE_H_
#define _PCRE_H_
#include <pcre.h>
#include <string>
#include <vector>
#include <string.h>
using namespace std;

const int VECSIZE = 30;

struct MatchResult
{
	string name;
	vector<string> value;
};

class Pcre
{
public:
	Pcre();
	~Pcre();

	//Add a regrex, pass in name and regrex
	int AddRule(const string &name, const string &patten);

	//clear all the regrex
	void ClearRules();

	//match all the regrex, also return all the string match to every regrex
	vector<MatchResult> MatchAllRule(const char content[]);

private:
	const char *error;
	int erroffset;
	int ovector[VECSIZE];
	vector<pcre*> re_arr;
	vector<string> patten_name;
};
#endif

Pcre.cpp

#include "Pcre.h"
#include <stdio.h>

Pcre::Pcre()
{
	re_arr.clear();
	patten_name.clear();
}

Pcre::~Pcre()
{
	for(int i=0; i<re_arr.size(); i++)
        {
                pcre_free(re_arr[i]);
        }
}

//Add a regrex patten and compile it.
int Pcre::AddRule(const string &name, const string &patten)
{
	pcre *re = pcre_compile(patten.c_str(), PCRE_MULTILINE|PCRE_UTF8|PCRE_NO_AUTO_CAPTURE, &error, &erroffset, NULL);
        if(re == NULL)
        {
                printf("pcre compile failed, offset %d: %s\n", erroffset, error);
		return -1;
        }
	else
	{
		re_arr.push_back(re);
		patten_name.push_back(name);
	}
}

//clear all the rule
void Pcre::ClearRules()

	for(int i=0; i<re_arr.size(); i++)
	{
		pcre_free(re_arr[i]); 
	}
	re_arr.clear();
	patten_name.clear();
}

//match all regrex, if any match, return the matched patten name and it's values
vector<MatchResult> Pcre::MatchAllRule(const char content[])
{
	vector<MatchResult> result_arr;
	int length = strlen(content);
	char buf[512];
	for(int i=0; i<re_arr.size(); i++)
	{
		MatchResult result;
		result.name = patten_name[i];
		int cur = 0;
		int rc;
        	while(cur<length && (rc = pcre_exec(re_arr[i], NULL, content, length, cur, PCRE_NOTEMPTY, ovector, VECSIZE)) >= 0)
        	{
                	for(int j=0; j<rc; j++)
                	{
				memset(buf, 0, sizeof(buf));
				strncpy(buf, content+ovector[2*j], ovector[2*j+1]-ovector[2*j]);
                        	result.value.push_back(buf);
                	}
                	cur = ovector[1];

 Google it , I found the thread about the error, a comment gives the solutions:

Building under Windows:

If you want to statically link this program against a non-dll .a file, you must
define PCRE_STATIC before including pcre.h, otherwise the pcre_malloc() and
pcre_free() exported functions will be declared __declspec(dllimport), with
unwanted results. So in this environment, uncomment the following line. */

//#define PCRE_STATIC

try it ... successful !!!!
