Bonjour,

Voici une information qui pourrait �tre utile � tous ceux qui se plaignent de la lenteur de la compilation de l'EDI lorsque les projets deviennent imposants :

Je serais tr�s heureux de tester. J'ai donc t�l�charg� le zip, mais... Comment �a s'installe ? Il contient deux BPL, que faut-il en faire ? J'ai essay� d'installer ce composant, mais aucune diff�rence.

Bonjour,

Il faut l'installer comme un paquet de composants (*.bpl) ordinaire.

Voila ce qu'on peut apprendre sur le thread du newsgroup ( http://groups.google.com/group/borland.public.cppbuilder.non-technical/browse_thread/thread/5abe3bfd133f745a/84c2667dc99b4ffe ) :

Thanks to tips from Graham Thompson I could install the .bpl in BCB5.
I did see nothing happen. And I could not imagine that installing
a .bpl could influence the compiler. I still don't understand. But the
results are amazing. My main project compiled in two minutes. I reported
that a year ago or so. Now it contains 288 units and it compiles and links
in about 30 seconds.

The package uses the "initialization" section to re-initialize the
compiler's callback functions.

Note : pour l'instant, je ne l'ai pas test� sur un projet de taille importante, je n'ai donc pas pu constat� l'effet de ce patch. N�anmoins, de nombreuses personnes de ce newsgroup l'ont test� avec de tr�s bons r�sultats.

Pas mal !

Test� sur un projet de 55 fiches..

compilation complete normale 2 minutes...
compilation complete avec le fix : 45 secondes ....

Bonjour,

L'auteur du patch a cr�� un site pour diffuser et am�liorer son plugin :

hum...c'est pas mal...mais un ou deux d�tail qui tra�ne.
par exemple, ne compile que les fichiers enregistr�s...pas forc�ment super pratique.

mais sinon c'est bien
