Bonjour
J'ai un problème lors de la compilation de mon makefile

Voila mon makefile

OPT = -Wall
CPPFLAGS=-I/usr/include/ImageMagick
LDFLAGS=-L/usr/lib -lMagickWand

all : menu projet.o Statistiques.o graph.o SelectionTrancheAge.o SelectionPays.o clean

menu: menu.c menu.h projet.o Statistiques.o SelectionTrancheAge.o SelectionPays.o graph.o
gcc `Wand-config --cflags --cppflags` `Wand-config --ldflags --libs` -o menu menu.c projet.o Statistiques.o SelectionTrancheAge.o SelectionPays.o graph.o $(OPT)

projet.o: projet.c projet.h
gcc -o projet.o -c projet.c $(OPT)

Statistiques.o: Statistiques.c Statistiques.h projet.o SelectionPays.o
gcc -o Statistiques.o -c Statistiques.c projet.o SelectionPays.o $(OPT)

SelectionTrancheAge.o: SelectionTrancheAge.c SelectionTrancheAge.h
gcc -o SelectionTrancheAge.o -c SelectionTrancheAge.c $(OPT)

SelectionPays.o: SelectionPays.c SelectionPays.h
gcc -o SelectionPays.o -c SelectionPays.c $(OPT)

graph.o : graph.c graph.h
gcc `Wand-config --cflags --cppflags` `Wand-config --ldflags --libs` -o graph.o -c graph.c

clean:
rm *.o


Et voila les erreurs affichées

compilé sur une autre machine j'ai ces erreurs
