linux交叉编译的Makefile

本文使用的交叉编译工具为arm-none-linux-gnueabi-gcc

其目录在   /pkg/asw/compilers/gnu/codesourcery/arm-2006q3-27/bin

内核树目录在/home/sein/work/router/lct_kernel/kernel

输出文件：hello.ko

 

先export交叉编译工具的位置

export PATH=/pkg/asw/compilers/gnu/codesourcery/arm-2006q3-27/bin:$PATH

 

 

以下是Makefile的内容
