pre fanusikov make

[Radovan Augustin]

Dobry den,

vas Makefile je v poradku.
make obsahuje implicit rule:
    { "%", "s.%",

"$(GET) $(GFLAGS) $(SCCS_OUTPUT_OPTION) $<" }
vid make -p


reseni je v Makefile pouzit target .PHONY:

.PHONY: bin
nebo spoustet make s prepinacem -r

make -r

taky jine suffixy nez '.bin' by nefungovali, napr '.asdf'

Co je zle na tomto makefile? Tabulatory su tam, kde treba. Preco nestaci
napisat "make", a musim napisat "make s.bin" aby mi to vyrobilo ten s.bin?
Ak do TARGET dam nieco ine, napr. "TARGET=t", tak "make" vytvori bez reci
t.bin.

(Podotykam, ze som to sam nedokazal vyriesit, musel mi napovedat kolega).
