List used header files as dependencies for the object files that use them, that way when a header is modified the objects that use it get rebuilt.

The problem is that the compiler generate other files when I do this

Abdelhaq El Amraoui What kind of other files? What i meant was just to have an explicit recipe for each object file - like module1.o: module1.c header1.h header2.h $(CC) $(CFLAGS) -c
lt; -o $@ (c file should be the first dependency in the list so that
lt; becomes it)

Also you can try using -MMD gcc option: https://codereview.stackexchange.com/questions/2547/makefile-dependency-generation/11109#11109 (never done it myself, but maybe that's what you need)
