compilation regex-0.12.tar.tar regex.exe

Version imprimable

Bonjour,

Je tente d'installer la biliiothèque regex avec cygwin 1.7.
Regex.exe à été compilé avec $ make test

Je l'ai placé dans cygwin/bin

J'obtiens,
Code:

1 2 3 4 5 6 7 etc rex.c:13: error: `REG_EXTENDED' undeclared (first use in this function) rex.c:19: warning: implicit declaration of function `regexec' rex.c:21: warning: implicit declaration of function `regfree' rex.c:39: warning: implicit declaration of function `regerror' etc
Qu'est-ce qui ne va pas?

Merci de votre attention,

Tu as oublié de faire un include du .h de la bibliothèque regex dans ton programme

L'include est dans le même dossier que ce programme copié collé du tutoriel regex. . .

Il est aussi dans C:/cygwin/usr/local/include/regex.h

#include <stdio.h>
#include <stdlib.h>
#include <regex.h>
 
int main (void)
{
   int err;
   regex_t preg;
   const char *str_request = "www.developpez.com";
   const char *str_regex = "www\\.[-_[:alnum:]]+\\.[[:lower:]]{2,4}";
 
/* (1) */
   err = regcomp (&preg, str_regex, REG_NOSUB | REG_EXTENDED);
etc
