完美編譯運行PCRE on Windows , Solved the __imp__pcre_exec __imp__pcre_compile __imp__pcre_free Errors

寫寫英文吧，好長時間不寫都有點不熟練了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 regrexint AddRule(const string &name, const string &patten);//clear all the regrexvoid ClearRules();//match all the regrex, also return all the string match to every regrexvector<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

 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 !!!!
