Bonjour,

Je suis en train de faire une simulation en C++ sous eclipse. À partir d'un moment donné, quand je lance l'exécution du programme, eclipse se ferme brusquement sans aucun signalement d'erreur.

Est-ce que quelqu'un peut m'aider pour cela.

Merci,

[therwald]

Es-tu certain qu'il n'y a aucun signalement d'erreur, rien du tout? (logs, message dans la console...?)
Sinon, on aura beaucoup de mal à aider sans plus d'informations...

Merci,

Voici ce que log file indique:

Parfois, cela indique "java heap space"; ensuite je modifie le fichier eclipse.ini mais Eclipse disparaît pendant l'exécution du programme.

On dirait que le problème vient de org.eclipse.ui.ide.prefs :

java.io.FileNotFoundException: C:\eclipseC\configuration\.settings\org.eclipse.ui.ide.prefs (Access is denied)

Essaye de changer les droits d'accès à ce fichier (fichier de configuration des préférences d'Eclipse)

Je suis l'admistrateur de la machine; j'ai donc tous les droits. Le problème persiste. Eclipse ne disparaît plus, mais le programme plante:
