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=/home/zeroway/3288/src/3288_4.4/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-gcc KERNELDIR=/home/zeroway/3288/src/3288_4.4/kernel

编译内核时有指定O选项

  • cd debug/hello
  • make CROSS_COMPILE=/home/zeroway/3288/51/src/3288_5.1_v2/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- KERNEL_DIR=/home/zeroway/3288/51/src/3288_5.1_v2/kernel KERNEL_BUID_OUTPUT=/home/zeroway/3288/51/src/3288_5.1_v2/out/target/product/rk3288/obj/KERNEL
