Erreur lors de la compilation d'un programmeC

et ton fichier include "internal.h", il se trouve où ?
Est-ce un fichierfait maison ?

de même #include <header>
#include "header.h"
résultat==>erreur: header : Aucun fichier ou dossier de ce type
erreur: header.h : Aucun fichier ou dossier de ce type
erreur: internal.h : Aucun fichier ou dossier de ce type

Re,

Si ça ne te déranges et si tu veux bien sûr tu peux coller ici le code pour essayer une compilation chez moi.

En fait, essaie de copier le fichier dans /usr/include

Si ça ne te déranges et si tu veux bien sûr tu peux coller ici le code pour essayer une compilation chez moi.
bien sûr que non.
voilà le code:

Vu que tu utilise le internal.h qui se trouve dans /usr/include/ecl alors mets

#include <ecl/internal.h>

je le met mais de même ecl/internal.h : Aucun fichier ou dossier de ce type.
je doute qu'il y a une bibliothèque qui me manque, je ne saie pas lequel ?

Affiche

ls -l /usr/include/ecl/internal.h 
dpkg --get-selections ecl

hamhoum@TALEL-PC:~$ ls -l /usr/include/ecl/internal.h

Mais tu n'as pas répondu à toutes mes questions ;-)

pour le main il existe dans le code :extern int ping_main(int argc, char **argv){
pour le code je l'ai téléchargé de forum.. j'ai oublié le nom du forum.
