Quelqu'un peut-il me venir en aide?

Bonjour.

Je ne vois pas de problème particulier dans ce que tu nous montres. Comme l'option "-Wdeprecated-declarations" est activé tu as des warnings pour les fonctions obsolètes. Mais elles sont toujours utilisables.

Puisque tu es sous Linux installe si ce n'est déjà fait Devhelp. Ca va te permettre d'avoir la documentation des bibliothèques sous la main. Ensuite installe libgtk2.0-doc.

tu pourras voir que gtk_type_init (); est obsolète (extrait de la doc.) :

gtk_type_init ()

void
gtk_type_init (GTypeDebugFlags debug_flags);
gtk_type_init is deprecated and should not be used in newly-written code.

Ainsi que GTimeVal :

struct GTimeVal

struct GTimeVal {
glong tv_sec;
glong tv_usec;
};
GTimeVal has been deprecated since version 2.62 and should not be used in newly-written code.
Use GDateTime or guint64 instead.

Oui effectivement ça marche en fait, merci de m'avoir répondu si vite
