代码make后出现的错误----为什么会出现这个错误，怎么改？

joyce@ubuntu:/mnt/hgfs/Share_With_Ubuntu/clink_test$ make
gcc -g -D_GNU_SOURCE -c collect.c
/tmp/ccrRmuk9.s: Assembler messages:

make: *** [collect.o] Error 1

makefile内容如下：

CC     = gcc
CFLAGS = -g -D_GNU_SOURCE
LFLAGS =
OFILES = collect.o process.o util.o source_db.o
HEADERS = clink.h

FILES = COPYRIGHT Makefile clink.doc clink.h collect.c process.c util.c  source_db.c

%.o: %.c $(HEADERS)
    $(CC) $(CFLAGS) -c $<

clink: $(OFILES)
    $(CC) $(LFLAGS) -o clink $(OFILES) -lm

tar:
    rm -f clink.1.0/*
    cp $(FILES) clink.1.0
    tar -cvf clink.1.0.tar clink.1.0
    tar -czf clink.1.0.tar.gz clink.1.0

注意：makefile中source_db的部分是我自己加的，请小板车指点为什么会出现这个错误
