在Linux内核中单独编译KO文件

在当前模块目录下创建Makefile： obj-m := mxt224.o

然后再该模块目录下打开终端输入：make -C /home/kernel_path/ M=$(pwd) modules

/home/kernel_path/ 是内核所在路径

或者用该makefile:

 #set KERNELDIR and CROSS_COMPILE path yourself
 #
 ifneq   ($(KERNELRELEASE),)
  obj-m   :=   mxt224.o
 else
  KERNELDIR   :=   /home/stone/stone_share/Project/t11/t11-2.3/kernel
  #KERNELDIR   :=   /home/bee/bee_share/mini6410/linux-2.6.36-android/linux-2.6.36-android
  #KERNELDIR   :=   /opt/mini6440/linux/linux-2.6.36
  PWD   :=   $(shell pwd)
  #CROSS_ARCH := ARCH=arm CROSS_COMPILE=/usr/local/arm/4.5.1/bin/arm-linux- #6410-linux-2.6.36
  CROSS_ARCH := ARCH=arm CROSS_COMPILE=/usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi-
 default:
  $(MAKE) $(CROSS_ARCH) -C  $(KERNELDIR)   M=$(PWD)   modules

 install:
  $(MAKE)  $(CROSS_ARCH) -C  $(KERNELDIR)   M=$(PWD)   modules_install
 clean:
  rm   -rf   *.o   *~   core   .depend   .*.cmd   *.ko   *.mod.c   .tmp_versions *.symvers *.d *.markers *.order

 .PHONY:   modules   modules_install   clean  main
 endif
