没有办法整体编译通过ldd2的源代码！！请求帮忙

在redhat9.0或者debian（2.4.27内核）下面就是没有办法整体编译通过ldd2（linux设备驱动程序，2nd）的源代码，会出现一大堆错误。提示如下：
zxh@debian:~/testSource/Ldd2/ldd2-samples-1.0.1$ make

for n in misc-progs misc-modules skull scull scullc scullp scullv sbull spull snull short shortprint pci simple usb allocator; do make -C $n || exit 1; done

make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/home/zxh/testSource/Ldd2/ldd2-samples-1.0.1/misc-progs'
make[1]: Entering directory `/home/zxh/testSource/Ldd2/ldd2-samples-1.0.1/misc-modules'

make[1]: *** [sleepy.o] 错误 1
make[1]: Leaving directory `/home/zxh/testSource/Ldd2/ldd2-samples-1.0.1/misc-modules'
make: *** [subdirs] 错误 1

尤其是这句提示“gcc: cannot specify -o with -c or -S and multiple compilations”不知道什么意思？但是如果在各个目录下面单个编译某个文件，都能够成功，也可以加载，我单个编译各个模块的makefile是这样的（这时debian的，如果在redhat9.0下面，就把kernel-headers-2.4.27-2-386换成linux-2.4.20-8就这可以）：
TARGET := hello
WARN := -W -Wall -Wstrict-prototypes -Wmissing-prototypes

#INCLUDE := -isystem /lib/modules/`uname -r`/build/include
CFLAGS := -O2 -DMODULE -D__KERNEL__ ${WARN} ${INCLUDE}
CC := gcc

${TARGET}.o: ${TARGET}.c
clean:
rm -rf *.o
