# Test 2 : Compilation où le résultat existe déjà
|
||||
|
||||
## Description
|
||||
Ce test vérifie que si l'exécutable `main` est déjà présent et que `main.c`
|
||||
n'a pas été modifié, alors `Bake` ne tente pas de recompiler.
|
||||
|
||||
## Fichiers utilisés
|
||||
- `main.c` : Fichier source inchangé.
|
||||
- `Bakefile` : Contient les règles de compilation.
|
||||
- `main` : Exécutable déjà généré.
|
||||
|
||||
## Résultat attendu
|
||||
Aucun message indiquant la compilation ne doit apparaître.
