如何使PCRE与Code :: blocks一起正常工作？

Question

I am facing some problems while working with PCRE in Code::blocks. I have downloaded PCRE from here . And did all the steps mentioned here . However I am getting a pcr3.dll missing error during execution.

The program can't start because pcre3.dll is missing from your computer. Try reinstalling the program to fix this problem.

My code :

#include <iostream>
#include <regex.h>
using namespace std;


 int main(){

 regex_t reg;

 string pattern = "[^tpr]{2,}";
 string str = "topcoder";

 regmatch_t matches[1];

 regcomp(&reg,pattern.c_str(),REG_EXTENDED|REG_ICASE);

 if (regexec(&reg,str.c_str(),1,matches,0)==0) {
       cout << "Match " ;
       cout << str.substr(matches[0].rm_so,matches[0].rm_eo-matches[0].rm_so) ;
       cout << " found starting at: " ;
       cout << matches[0].rm_so ;
       cout << " and ending at " ;
       cout << matches[0].rm_eo ;
       cout << endl;
  } else {
       cout << "Match not found.";
       cout << endl;
 }
 regfree(&reg);

  return 0;
 }

I am not sure how to fix this, any ideas?

PS: Above mentioned code is taken from this tutorial.

Answer 1

Copy the DLL to the same directory as the executable that you are running. If that works, you didn't install the DLL correctly or at least not in a way that it can be found by the programs in general. Check out the documentation of the DLL Search Order to get an idea how else you can make the system find the DLL. In particular, you need to know that there is a linker and a loader (aka dynamic/runtime linker/loader), but only one of them is configured inside CodeBlocks!
