Problème pour la compilation du driver IOHIDFamily sous Tiger

[claque2000]

Voila, pour un projet, je dois modifier l'extension IOHIDFamily, une des fonctionnalités de cette extension étant prise en charge par mon projet d'une façon autre que dans l'extension. Le problème qui se pose à moi est la compilation du module en lui même. J'ai téléchargé les sources de IOHIDFamily-164, correspondantes au module IOHIDFamily pour 10.4.1. Et en fait, la compilation me sort 77 erreurs, qui sont toutes un problème avec absolutetime. Y'a-t-il des headers à télécharger, comment compiler un module du noyau sous tiger ?

Pour plus de clarté, voici les erreurs affichées par Xcode lors de la compilation :

etc..

D'après les erreurs, ça ne me semble pas être un problème de header manquant. Est ce que ce serait gcc4.0 qui soit trop restrictif ?
Merci pour votre aide.

Essaye de faire un simple cast.

Sinon, ça vient du fait que le KPI a changé depuis Tiger. Il y a certainement une structure de remplacement sur le site d'Apple.

Le cast devrait fonctionner.
Pour les constantes, essaye de les redéclarer.

Sinon, tu as les mailing list d'Apple ou les gens te répondront rapidement.
Pour les drivers, c'est le meilleur moyen d'obtenir des réponses?

 

[claque2000]

Bon plein de casts explicites et redéfinition des fonctions et ça marche. Merci

 

[SuperCed]

Tu devrais poster quand même la question sur la mailing list Apple pour savoir si ça va pas poser problème dans le futur.

Et tiens nous au courant

 

[claque2000]

La question a été posée et la réponse qui m'a été faite est que Tiger utilise gcc4.0 par défaut avec Xcode mais le système en lui même aurait été compilé avec gcc3.3 et gcc4.0 est plus restrictif et tout cast doit etre explicit si c'est pas une conversion triviale de float vers int par exemple.

Bonjour,

Sous Xcode, dans les setting de la target, GCC compiler settings, tu peut choisir GCCv3.3.

A ce propos, as-tu eu l'occasion de tester un peu plus en détail gcc 4?

Génère-t-il un code plus rapide à l'éxécution?
Compile-t-il aussi vite que CodeWarrior?

As-tu testé les fonction de vectorisation automatique? Doit-on donner des indications au précompilateur comme pour VAST-C?

Un peu.

Je n'ai pas vue de difference perceptible.

Compile-t-il aussi vite que CodeWarrior?

Tu compare une deux chevaux avec une ferrari...

As-tu testé les fonction de vectorisation automatique? Doit-on donner des indications au précompilateur comme pour VAST-C?

Non, je n'ai pas essayé cela.

J'ai voulu mettre des coups de boule pour ta réponse, mais a priori, je dois en donner à d'autres avant...
