C getline() seem not working !?

[lucrol]

Hello,
In a C program writen with Code::Blocks 13.12, I try to use the getline() function, but the compiler send an error

undefined reference to 'getline'

(I put #include <stdio.h> in my header).
Here is my test code :

Code

/* Test_getline.c : acquisition sécurisée d'une ligne de texte
*/
#include <stdio.h>
#include <stdlib.h>

int main()
{
  int bytes_len = 80;                                 // taille de la chaîne
  int bytes_read;
  char *my_string;

  my_string = (char *) malloc(bytes_len + 1);          // +1 pour \n

  puts ("Saisir une ligne de texte : ");
  if ((bytes_read = getline(&my_string, &bytes_len, stdin)) == -1)
    {
      puts("Erreur de saisie !");
      return -1;
    }
  else
    {
      printf("Saisie de %d caractères : %s", bytes_read, my_string);
      return 0;
    }
}

What's the matter ?
Bests regards.

it work on linux

Code

# gcc test.c -o test
# ./test
Saisir une ligne de texte :
vxcvxcv
Saisie de 8 caractères : vxcvxcv

Both getline() and getdelim() are GNU extensions. They are available
since libc 4.6.27.

it work on linux

Yes, but don't works on Windows ! (C::B v13.12)
Need a specific Library ?

first of all: Codeblocks is not a compiler....

your question is 100% compiler (or libc) specific, and so this forum is the wrong place to post such questions.
