我的Makefile是这样的
obj-m:=a.o
ssr-objs:=b.o c.o d.o

KDIR:=/lib/modules/$(shell uname -r)/build
PWD:=$(shell pwd)
EXTRA_CFLAGS := -ffast-math -DREDHAT9 -mhard-float -O2 -Wall -fomit-frame-pointer
#EXTRA_CFLAGS := -ffast-math -mhard-float -O2 -Wall -fomit-frame-pointer
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
clean:
rm -rf *.o

[root@mytest kernel]# make
make -C /lib/modules/2.4.20-8/build SUBDIRS=/home/ssr_linux/src/kernel modules
make[1]: Entering directory `/usr/src/linux-2.4.20-8'

The present kernel configuration has modules disabled.
Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled.

make[1]: *** [modules] Error 1

make menuconfig
然后进入Loadable module support, 选中Enable loadable module support

上午重新编译内核....失败,,,我把过程写上

1:  cd /usr/src/linux-2.4.20-8
2:  make mrproper
3:  make menuconfig (那个Enable loadable module support本来就是*的,我没做其它的就直接保存退出)

4:  make dep
5:  make bzImage
6:  make modules
7:  make modules_install
8:  cp System.map /boot/System.map-2.4.20-8-10-new
cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.20-8-10-new
10: cd /boot
rm -rf System.map
rm -rf vmlinuz
11:  ln -s System.map-2.4.20-8-10-new System.map
   ln -s vmlinuz-2.4.20-8-10-new vmlinuz

12:  vi /boot/grub.grub.conf
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-

      root (hd0,0)
      kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
      initrd /initrd-2.4.20-8.img

title Red Hat Linux (2.4.20-8-new)
      root (hd0,0)
      kernel /vmlinuz-2.4.20-8-10-new ro root=LABEL=/
      initrd /initrd-2.4.20-8.img

重启系统:进2.4.20-8-new失败
进原来的内核2.4.20-8之后
