sudo make 时候出现的问题

[vsfly]

make文件是这样的：

# Linux or Windows:
CC = gcc -Wall -O4 -march=i486
# CC = icc -w1 -O3 -march=i486

# Macintosh:
ifeq ($(HOSTTYPE),powerpc)
  CC = cc -pipe -O3 -Wall -fno-common -arch ppc
endif

LIBS=-lm
OBJ=svdlib.o svdutil.o las2.o

svd: Makefile main.o libsvd.a
	${CC} ${CFLAGS} -o svd main.o libsvd.a ${LIBS}
	mv -f $@ ${HOSTTYPE}/$@
	ln -s ${HOSTTYPE}/$@ $@
main.o: Makefile main.c svdlib.h
	${CC} ${CFLAGS} -c main.c

libsvd.a: ${HOSTTYPE} ${OBJ}
	rm -f $@ ${HOSTTYPE}/$@
	ar cr $@ ${OBJ}
	ranlib $@
	mv -f $@ ${HOSTTYPE}/$@
	ln -s ${HOSTTYPE}/$@ $@
svdlib.o: Makefile svdlib.h svdlib.c
	${CC} ${CFLAGS} -c svdlib.c
svdutil.o: Makefile svdutil.c svdutil.h
	${CC} ${CFLAGS} -c svdutil.c
las2.o: Makefile las2.c svdlib.h svdutil.h
	${CC} ${CFLAGS} -c las2.c
clean: 
	rm *.o

$(HOSTTYPE):
	if test ! -d $(HOSTTYPE); \
	then mkdir $(HOSTTYPE); fi

Ubuntu下 sudo make后出现

rm -f libsvd.a /libsvd.a
ar cr libsvd.a svdlib.o svdutil.o las2.o
ranlib libsvd.a
mv -f libsvd.a /libsvd.a
ln -s /libsvd.a libsvd.a
ln: 创建符号链接 “libsvd.a”: 操作不允许
make: *** [libsvd.a] 错误 1

sudo allows a permitted user to execute a command as the superuser or another user.
Pls makesure you got a superuser permission.
I could successful exec those commands under Ubuntu.

你手动运行一下命令吗
还有，弄到根目录去做什么？
