使用方法(单独编译模块)或者放到内核目录中编译

• make CC=your_compiler_path KERNELDIR=your_kernel_dir

举例(以hello模块为例)

编译内核时没有指定O选项

• cd debug/hello
• make CC=/3288androidsrc/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-gcc KERNELDIR=/3288androidsrc/kernel

编译内核时有指定O选项

• cd debug/hello
• make CROSS_COMPILE=/3288androidsrc/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- KERNEL_DIR=/3288androidsrc/kernel KERNEL_BUID_OUTPUT=/3288androidsrc/out/target/product/rk3288/obj/KERNEL
