Why not try with the defaults, no option at all?
Header files (.h) are "included" in the source .c files.

Then try options when it works.
Here is the simplest possible makefile, called from emacs with "make =
-k".
(I guess you'll not worry about some French in it :-).

# Makefile pour main
# -o : output, nom du fichier de sortie
# Objects : fichiers objets =E0 inclure dans le fichier de sortie

objects=3D main.rel serial.rel

main: $(objects)
         sdcc -o main.hex --model-large $(objects)
# la fa=E7on de les r=E9unir

.SUFFIXES: .rel
.c.rel:
         sdcc --model-large -c $<
# la fa=E7on de produire .rel =E0 partir de .c

Thanks for your help
1- I modified my Makefile as you proposed so stdout is
.\sdcc\bin\sdcc -c main.c -I.\sdcc\include
.\sdcc\bin\sdcc -c serial.c -I.\sdcc\include
.\sdcc\bin\sdcc main.rel serial.rel -o agitateur.ihx

No error in compilation... Code size is 4893 bytes but doesn't work.

2- I tested to automaticly concatenate the 2 .c files with
		$(RM) -f onefile.c
		$(CAT) serial.c main.c > onefile.ctemp
		$(MV) onefile.ctemp onefile.c
		$(CC) onefile.c  -I.\sdcc\include -o onefile.ihx
		$(RM) onefile.c
No error in compilation... Code size is 4897 bytes and it works =
!!!!!!!!!

Strange 4 bytes difference ??????????
