Bonjours a tous,

J'ai un petit probleme: mon programme est instable et il plante de facon plus ou moins aleatoire... (quand je dis plus ou moins c'est que je sais quelles manops faire pour le planter mais que cette meme manip ne le plante pas toujours...).
Donc avant de ma tourner vers vous j'ai cherché... et j'ai utiliser pour la premiere fois un debugger: GDB (sous linux ) apres quelque correction ca va mieux mais j'ai toujours ces 3 rapports de GDB que je ne comprend pas... (je les obtient en faisant "where" ):

Premierement celui ci, je n'y vois que des erreur GTK+ vous assi? si non vous avez peut etre une idee de ou ca vient ?

Et puis il y a celui la... comme vous pouvez le voir il y 2 lignes (12 et 13) qui m'indique mon code, or cette a cette ligne j'ai la fonction "gtk_list_store_clear( blabla )" qui detruit une list... sauf que je vois vraiment pas pourquoi des fois ca marche et des fois pas...

ET enfin ^^ j'ai ce rapport la (c'est le dernier ): la GDB me dis que il y un truc bizar ligne or il s'agit de ma boucle evenementiel "gtk_main();" qui gere tout mon affichage arggg surtout qu'elle plante aussi de facon aleatoire...

Voila voila, je n'ai pas eu d'autres rapports differents de la part de GDB (ouf!) donc si quelqu'un a eu la courage de tout lire et et a une idee a ma soumettre qu'il n'esite pas
Au pire si quelqu'un a une meillieur facon pour debugger du GTK+ qu'il n'esite pas non plus

Merci d'avance

[teuf13]

Plantage aléatoire + backtrace qui plante dans un malloc ou un free, ca sent la corruption mémoire. Pour debugger ça, valgrind est beaucoup plus adapté que gdb.

[bobyboby]

J'ai eu une fois un programme qui plantait au hasard et les erreurs montrées par le debugger n'étaient pas représentatives.
Il s'agissait d'un problème de memoire du a une variable ou un pointeur que j'avais ouiblié d'initialiser. vérifie bien de ce coté la, car si ca plante au hasard en général c'est que la valeur de ta variable prise par defaut est parfois possible parfois impossible et ca plante. En esperant que ça t'aide.

[teuf13]

Valgrind détecte ces cas là aussi et donne une indication sur le problème. Sinon, quand tu compiles avec gcc en -O2 -Wall -Werror, je crois que t'as un warning qui te préviens quand t'essaie d'utiliser une variable non initialisée

[DarkSubulba]

Salut,
Ca fais plaisir de voir que vous m'avais repondu, merci

Sinon, quand tu compiles avec gcc en -O2 -Wall -Werror, je crois que t'as un warning qui te préviens quand t'essaie d'utiliser une variable non initialisée

En faite j'utilise toujour l'argument -Wall et meme avec les autre je n'ai rien d'affiché, tout compile parfaitement...

Sinon j'ai testé valgrind, il est impressionnant! Mais j'avous pas comprendre la premiere erreur:

-------------------------- 2 ----------------------------

en effet dans mon programme cela est codé par:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
puts("-------------------------- 1 ----------------------------");
	gtk_init(&argc, &argv);
puts("-------------------------- 2 ----------------------------");

Autrement dis j'ai un probleme des le debut avec GTK_init
Il y a peut etre une erreur de type ou un truc que j'ai pas initialisé, pourtant je n'ai vu nul pars qu'il fallait faire autrement...

Alors que comment est organisé mon programme? comme ca:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
9
10
11
int main (int argc, char **argv) {
 
//blabla
// Plusieurs fonctions d'initialisations
//blabla
 
	Interface_graphique (argc, argv,ptr_global);					
 
return 0;	
 
}

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
9
10
11
12
int Interface_graphique (int argc, char **argv, GLOBAL *ptr_global) {
 
puts("-------------------------- 1 ----------------------------");
	gtk_init(&argc, &argv);
puts("-------------------------- 2 ----------------------------");
 
//blabla...
// tout ce qui concerne l'interface avec les GTK_connect pour les bouton etc...
//blabla
 
return 0;
}

et tout mes GTK_widget et autre sont declarer dans une structure appeler OBJETS et dans la quelle il y a egalement un pointeur vers la structur GLOBAL qui comporte plein d'infos initilaliser avant le lancement de ma fonction Interface_graphique.

Donc pour vous donner une idee je declare ma fenetre (dans la fonction_interface graphique) comme cela:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
objets.ptr_fenetre_principale = gtk_window_new (GTK_WINDOW_TOPLEVEL);						
	gtk_window_set_position (GTK_WINDOW(objets.ptr_fenetre_principale), GTK_WIN_POS_CENTER);

Voila, j'espere vous avoir donnée assez d'infos comprehensible et surtout utiles ^^
Je vais continuer a chercher mais j'avous etre depasser par cette erreur sur le GTK_init...

Bonne soirée a tous

[gege2061]

Bonjour,

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

gtk_init(argc, argv);

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

gtk_init(&argc, &argv);
