Narrow your problem down and provide a Short, Self Contained, Correct (Compilable), Example. –Yu Hao Dec 11 '13 at 8:56 A couple of suggestions: in the main recipe, you can write: $(COMPILER) -o $@ $^ $(LDFLAGS) and put -pthread in LDFLAGS. In the other rules you can write once: %.o: %.c and as recipe: $(COMPILER) $(CCFLAGS) -c -o $@ $< (and not give the .h to the compiler!) and later add dependency
