Da li se fajl D2AS6INC.F zove ovako ili d2as6inc.f ?

Promenio sam na velika slova ali sad ide:
f77 -O3 -C SURFCE.F -O SURFCE.O
surfce:
gcc: SURFCE.O: No such file or directory
f77 -O3 -C PHASE.F -O PHASE.O
phase:
gcc: PHASE.O: No such file or directory
f77 -O3 -O SURFACE SURFCE.O PHASE.O
gcc: SURFACE: No such file or directory
gcc: SURFCE.O: No such file or directory
gcc: PHASE.O: No such file or directory
Sad ga uopste ne vidi mada sam izmenio i makefile.

Evo kako mi izgleda makefile:
#
F77= f77
FLAGS= -O3

# Executable
SURFACE: SURFCE.O PHASE.O D2AS6INC.F
$(F77) $(FLAGS) -O SURFACE SURFCE.O PHASE.O

# Object files
SURFCE.O: SURFCE.F PHASE.F D2AS6INC.F
$(F77) $(FLAGS) -C SURFCE.F -O SURFCE.O
PHASE.O: PHASE.F
$(F77) $(FLAGS) -C PHASE.F -O PHASE.O

Mogu da dobijem jedan ls -l tog direktorijuma gde se nalaze potrebni fajlovi.

Naravno da mozes:
milenko@hp6830s:~$ ls surface
