[fsshl]

I like to compile some source, its Makefile is
----------------------------------------------------
# cat Makefile
# SPECapc Makefile for UNIX and Linux systems
# Contents \uffff Copyright 2001, Standard Performance Evaluation

# You must set the flags below as required to compile on the target
system

# hp8k ANSI needed for prototypes
# COPTS = -Ae
CFLAGS = $(COPTS) -O -c

clean:
        rm $(PRO_MACHINE_TYPE)/utilities.o
$(PRO_MACHINE_TYPE)/proescore.o $(PRO_MACHINE_TYPE)/config.o
$(PRO_MACHINE_TYPE)/proescore $(PRO_MACHINE_TYPE)/config

all: config proescore


config: $(PRO_MACHINE_TYPE)/config.o $(PRO_MACHINE_TYPE)/utilities.o
        $(LINKER) -o $(PRO_MACHINE_TYPE)/config
$(PRO_MACHINE_TYPE)/config.o $(PRO_MACHINE_TYPE)/utilities.o $(LDFLAGS)


proescore: $(PRO_MACHINE_TYPE)/proescore.o
$(PRO_MACHINE_TYPE)/utilities.o
        $(LINKER) -o $(PRO_MACHINE_TYPE)/proescore
$(PRO_MACHINE_TYPE)/proescore.o $(PRO_MACHINE_TYPE)/utilities.o -lm
-lX11

$(PRO_MACHINE_TYPE)/utilities.o: utilities.c
        $(CC) $(CFLAGS) utilities.c -o$(PRO_MACHINE_TYPE)/utilities.o

$(PRO_MACHINE_TYPE)/proescore.o: proescore.c
        $(CC) $(CFLAGS) proescore.c -o$(PRO_MACHINE_TYPE)/proescore.o

$(PRO_MACHINE_TYPE)/config.o: config.c
        $(CC) $(CFLAGS) config.c -o$(PRO_MACHINE_TYPE)/config.o

----------------------------------------------------------------------------------
so I type make, but it response
---------
# make
rm /utilities.o /proescore.o /config.o /proescore /config
rm: cannot remove `/utilities.o': No such file or directory
rm: cannot remove `/proescore.o': No such file or directory
rm: cannot remove `/config.o': No such file or directory
rm: cannot remove `/proescore': No such file or directory
rm: cannot remove `/config': No such file or directory
make: *** [clean] Error 1
------------------

for me, it seems Makefile did not call c compiler before clean(rm)

please help
