[GTK+ C] Chronomètre : problème de structure +jouer un son

Version imprimable

Bonjour,

j'ai fait un petit programme en GTK+ avec trois fichiers : main.c, fonctions.c et header.h (Source ci-dessous)
Le programme fonctionne mais j'ai deux soucis :

- si j'ai le malheur d'ajouter un champs, voire augmenter la taille d'un des tableaux de ma structure GADGET, mon programme ne démarre pas.. je pense à un problème de mémoire mais je n'arrive pas à le résoudre . Est ce du à l'appel périodique d'une fonction. J'ai toujours utilisé cette structure et jusqu'ici je n'ai jamais rencontré ce problème.

- J'aurais aimé jouer un son quand le chrono arrive à 0. Comment faire ?

Merci pour vos réponses.

pour jouer des sons, essayes avec fmod. C'est très puissant et simple d'utilisation

Merci pour ta réponse :)

Mais n'y a t-il pas plus simple ? Je n'ai pas vraiment envie d'ajouter une autre bibliothèque et apprendre à l'utiliser pour faire un vulgaire "pouet" ou un "tsoin tsoin" quelconque.
En revanche j'aimerais mettre autre chose que :
Code:

1 2 printf("%c",7);
J'ai toujours mon problème de mémoire aussi... :oops: (dans mon programme ;) )

Comment émettre un bip sonore ? ?

J'aurais aimé pouvoir envoyer un autre son qu'un bip. :)

Et j'ai toujours mon p'tit problème de mémoire ... :oops:

Pour ton problème de mémoire, as-tu tenté de lancer ton programme avec valgrind pour voir si ça te donne une piste ?

J'aurais aimé pouvoir envoyer un autre son qu'un bip. :)

Dans ce cas il faut passer par une autre bibliothèque pour lire un fichier audio. Regarde du côté de fmod, je crois qu'elle est spécialisée dans ce domaine ;)

ok merci Gege2061.. je crois que je vais me contenter de mon petit bip pour l'instant. :)
Pour la mémoire j'ai testé le programme avec gdb.. c'est ça ?
Rapelle de la structure :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 typedef struct GADGET GADGET; struct GADGET { GtkWidget * fenetre[1]; GtkWidget * VBox[1]; GtkWidget * HBox[2]; GtkWidget * bouton[4]; GtkWidget * entree[3]; time_t temps; gboolean chrono; //valeur retournée dans la fct° périodique guint test; //numéro du processus };
si par exemple je mets GtkWidget * entree[4]; à la place de GtkWidget * entree[3] j'obtiens : (avec 3 tout va bien)

si quand j'écris valgrind, tu lis gdb, va voir un opticien au plus vite ! :-p

rhoooooooo :lol:
Je croyais que c'étais pareil... je connais pas valgrind
Bon je me renseigne :P

Edité : ça m'a l'air bien compliqué. Je n'arrive pas à le faire fonctionner.
Une petite aide serait la bienvenue ;)

J'ai peut être mal cherché mais je n'ai pas trouvé d'explication claire pour installer fmod dans codeblocks sous Linux Debian .. je crois y être arrivée après qq essaies voilà comment je m'y suis prise pour ceux qui cherchent : (Je n'ai pas encore appris à utiliser cette bibliothèque donc je n'ai pas encore pu voir si mon installation est vraiment correcte. En tout cas quand je compile le mini programme je n'ai aucune erreur).

1. Déjà il faut télécharger la bibliothèque fmod 3 (et pas ex) ici

2. Vous décompactez le fichier téléchargé où vous voulez (je vais l'appeler "chemin")

3. Vous créez un dossier FMOD dans /usr/include/ ainsi :

Code:

# mkdir /usr/include/FMOD

4. Vous y copiez les 4 header du dossier /api/inc/ que vous avez téléchargé :
Code:

1 2 3 4 5 #cp /chemin/api/inc/fmoddyn.h /usr/include/FMOD/fmoddyn.h #cp /chemin/api/inc/fmod_errors.h /usr/include/FMOD/fmod_errors.h #cp /chemin/api/inc/fmod.h /usr/include/FMOD/fmod.h #cp /chemin/api/inc/wincompat.h /usr/include/FMOD/wincompat.h
5. Vous renommez le fichier libfmod-3.75.so du dossier "api" en libfmod.so pour qu'il soit reconnu puis vous le copiez dans le dossier /usr/lib/
Code:

1 2 #cp /chemin/libfmod.so /usr/lib/libfmod.so
6. Dans codeblocks ouvrir un nouveau projet console que vous pouvez appeler fmod

7. Inclure fmod avec
Code:

1 2 #include <FMOD/fmod.h>
8. Dans les options de compilations du projet ( Project/build options/ compiler settings/Other options/) mettre : -lfmod

9. Vérifier si tout se passe bien en compilant le projet. Vous pouvez utiliser ce fichier main.c
Code:

1 2 3 4 5 6 7 8 9 10 11 12 #include <stdio.h> #include <stdlib.h> #include <FMOD/fmod.h> int main() { FSOUND_Init(44100, 32, 0); FSOUND_Close(); return 0; }
J'obtiens :

Citation:

Checking for existence: /home/pseudo/programmation/FMOD/bin/Debug/fmod
Executing: xterm -T fmod -e /usr/bin/cb_console_runner /home/pseudo/programmation/FMOD/bin/Debug/fmod (in /home/pseudo/programmation/FMOD/.)
Process terminated with status 0 (0 minutes, 2 seconds)

10. Enregistrer le projet en tant que template utilisateur (Save project as user-template ) pour pouvoir ouvrir des projets FMOD rapidement.

Les compléments d'information sont les bienvenus. Merci :D

Edité : [valgrind] m'a l'air bien compliqué. Je n'arrive pas à le faire fonctionner.
Une petite aide serait la bienvenue ;)

il suffit de faire "valgrind ./monprogramme" et d'attendre et ensuite d'analyser le résultat, c'est pas trop compliqué à lancer normalement, c'est l'analyse du résultat qui peut être plus complexe :)

J'ai installé valgrind, et ensuite j'ai tapé valgrind monprogramme dans le dessier du programme. J'obtiens :
Code:

1 2 valgrind: ChronoGTK: command not found
Alors je suis allée faire un tour dans google pour trouver des tuto... c'est pour ça que je trouvais ça compliqué.
J'ai veriéfié j'ai bien valgrind dans /usr/bin/ pourtant :?

Valgrind va te donner un tas d'information lors du fonctionnement de ton programme. La lecture de ces informations n'est pas très simple mais tout de même faisable.

La ligne de commande est la suivante pour une utilisation classique :

Code:

valgrind --leak-check=full ./monprogramme

Tu dois être dans le répertoire de monprogramme et il doit y avoir l'option "-g" lors de la compilation.

Merci ! Je viens d'essayer et ça marche. Voici le résultat, effectivement je n'y comprends pas grand chose ... :oops:

La partie intéressante se trouve ci-dessus, valgrind commence par te dire qu'à la ligne 24 de fonctions.c, tu fais un test sur une valeur qui n'a jamais été initialisée, idem pour le GtkWidget que tu passes en argument à gtk_widget_destroy à la ligne 26. Le crash semble découler de l'utilisation de cette zone mémoire que tu n'as jamais initialisée

Merci ! C'est magique.
La fonction concernée dans fonctions.c est :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 //choix chrono ou décompte void accueil(GADGET *p_gadget) { if (p_gadget->VBox[0]) // ligne 24 { gtk_widget_destroy(p_gadget->VBox[0]); //ligne 26 } p_gadget->VBox[0]=gtk_vbox_new(TRUE,0); gtk_container_add (GTK_CONTAINER(p_gadget->fenetre[0]),p_gadget->VBox[0]); p_gadget->bouton[0]= gtk_button_new_with_label("Chronomètre") ; p_gadget->bouton[1]= gtk_button_new_with_label("Décompte") ; gtk_box_pack_start(GTK_BOX(p_gadget->VBox[0]),p_gadget->bouton[0],TRUE,TRUE,0); gtk_box_pack_start(GTK_BOX(p_gadget->VBox[0]),p_gadget->bouton[1],TRUE,TRUE,0); gtk_widget_show_all(p_gadget->fenetre[0]); g_signal_connect(G_OBJECT(p_gadget->bouton[0]), "clicked", G_CALLBACK(chrono), (gpointer)p_gadget); g_signal_connect(G_OBJECT(p_gadget->bouton[1]), "clicked", G_CALLBACK(decompte), (gpointer)p_gadget); g_signal_connect(G_OBJECT(p_gadget->fenetre[0]), "destroy", G_CALLBACK(quitter), NULL); }
Quand le programme commence rien a été affiché dans la fenêtre et je détruis la boîte gadget.Vbox [0].
Je pensais que ce test allait éviter le problème, et bien non... suis je bête, on ne peux pas voir si une valeur non initialisée existe !! :roll:
Il m'a suffit d'initialiser la boîte avant d'appeler la fonction et le problème a été réglé.
En tout cas m erci à tout le monde.
