# 'make' has an implicit rule for updating a ‘.o’ file #
|

# from a correspondingly named ‘.c’ file #
|
||||
# using a ‘cc -c’ command. #
|
||||
# Implicit rules are listed and applied in a predefined order (C before P...) #
|
||||
# Predefined implicit rules are implemented in make as suffix rules #
|
||||
# The default suffix list is: .out, .a, .ln, .o, .c, .cc, .C, .cpp, .p,... #
|
||||
# Rules whose suffixes fail to be on the list are disabled. #
|
||||
# You can define your own implicit rules by writing pattern rules. #
|

#------------------------------------------------------------------------------#
|
||||
|
||||
# If there are many implicit rules with the same target pattern,
|
||||
# the rule that actually applies is the one whose prerequisites exist or can be made

# ex: a .o can be made from a .c (C compiler) or a .p (Pascal compiler)

# More docs :
|

# https://www.gnu.org/software/make/manual/
|
||||
|
||||
# Makefiles contain five kinds of things:
|
||||
# explicit rules, implicit rules, variable definitions, directives and comments.
|
||||
|
||||
|
||||
# Variables automatiques --------------------------------------------------
|
||||
# $@ fait référence à la cible de la règle (au nom de la cible).
|
||||
# $< fait référence à la première dépendance.
|
||||
# $? fait référence aux noms de touess les dépendances plus récentes que la cible.
|
||||
# = les fichiers qui ont été modifiés après la compilation de code la plus récente
|
||||
# $^ fait référence aux noms de touess les dépendances avec des espaces entre eux.
|
||||
|
||||
# Variables implicites -------------------------------------------------
|
||||
# VPATH Équivalent utilitaire de la variable PATH de Bash. Vide par défaut.
|
||||
# Les chemins sont séparés par le signe deux-points (:).
|
||||
# CC Le programme pour compiler des fichiers C.
|
||||
# La valeur par défaut est cc. (Habituellement, cc pointe vers gcc.)
|
||||
# CPP Le programme qui exécute le préprocesseur C.
|
||||
# La valeur par défaut est $ (CC) -E.
|
||||
# LEX Le programme qui transforme les grammaires lexicales en code source.
|
||||
# La valeur par défaut est lex. (Vous devriez remplacer cela par flex.)
|
||||
# LINT Le programme qui lint votre code source. La valeur par défaut est lint.
|
||||
# RM La commande pour supprimer un fichier. La valeur par défaut est rm -f.
|
||||
# CFLAGS Contient tous les indicateurs du compilateur C (cc).
|
||||
# CPPFLAGS tous les indicateurs du préprocesseur C.
|
||||
# .PHONY Spécifie des cibles qui ne ressemblent pas au nom d'un fichier.
|
||||
# Un exemple est la cible "make clean" ; où clean est une valeur de .PHONY
|
||||
|
||||
# Syntaxe de Base
|
||||
# Règles : Une règle se compose d'une cible, des dépendances et des commandes.
|
||||
# Elle est généralement structurée comme suit :
|
||||
# cible: dépendances
|
||||
# commande
|
||||
#
|
||||
# La cible (target) est le fichier à générer,
|
||||
# les dépendances (prerequisites) sont les fichiers requis pour construire la cible
|
||||
# et les commandes (recipe) sont les instructions exécutées pour créer la cible.
|
||||
#
|
||||
# A simple makefile consists of “rules” with the following shape:
|
||||
# target ... : prerequisites ...
|
||||
# recipe
|
||||
# ...
|
||||
# A target is usually the name of a file that is generated by a program;
|
||||
# examples of targets are executable or object files.
|
||||
# A target can also be the name of an action to carry out, such as ‘clean’
