一、先了解编译驱动需要什么？

1、完整编译kernel的环境，驱动编译需要依赖kernel的生成物；
2、编译器及编译选项；
3、将所需环境变量配置在当前mk里；
注意只适用于ko模块编译

二、配置makefile

1、在Android系统编译LOG上找到编译器信息（一般都会打印出来）

如下
[2025-03-06T15:17:09.378Z] make -C /home/code/android/kernel/5.15_14 ARCH=arm CROSS_COMPILE=/home/code/android/prebuilts/mtk_toolchain/gcc-arm-linux-gnu-5.5.0-ubuntu/x86_64/bin/arm-linux-gnueabi- LOADADDR=0x20008000 NM=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-nm AR=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-ar LD=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/ld.lld OBJDUMP=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-objdump OBJCOPY=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-objcopy LLVM=1 LLVM_IAS=1 CC=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/clang O=/home/code/android/out/target/product/mt9633/obj/KERNEL_OBJ/5.15_14 BUILD_NUMBER= mtk_dtv_platform=mt5873 olddefconfig
[2025-03-06T15:17:09.378Z] make[2]: Entering directory ‘/home/code/android/kernel/5.15_14’
[2025-03-06T15:17:09.378Z] make[3]: Entering directory ‘/home/code/android/out/target/product/mt9633/obj/KERNEL_OBJ/5.15_14’

2、基于源MK构造 可独立运行的makefile

ccflags-y += -DANDROID_PLATFORM
KDIR ?= /home/builder/code/android/out/target/product/mt9633/obj/KERNEL_OBJ/5.15_14
ARCH ?= arm
CROSS_COMPILE ?= /home/code/android/prebuilts/mtk_toolchain/gcc-arm-linux-gnu-5.5.0-ubuntu/x86_64/bin/arm-linux-gnueabi-
OTHER_PARAMS ?= LOADADDR=0x20008000 NM=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-nm AR=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-ar LD=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/ld.lld OBJDUMP=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-objdump OBJCOPY=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/llvm-objcopy LLVM=1 LLVM_IAS=1 CC=/home/code/android/kernel/build-master/prebuilts/clang/host/linux-x86/clang-r487747c/bin/clang

all: modules
modules:
make -C $(KDIR)M=$(PWD) ARCH=$(ARCH)CROS{S}_{C}OMPILE=$(CROSS_COMPILE) $(OTHER_PARAMS) modules
$(CROSS_COMPILE)strip --strip-debug aic8800_fdrv/aic8800_fdrv.ko
$(CROSS_COMPILE)strip --strip-unneeded aic8800_fdrv/aic8800_fdrv.ko
$(CROSS_COMPILE)strip --strip-debug aic_load_fw/aic_load_fw.ko
$(CROSS_COMPILE)strip --strip-unneeded aic_load_fw/aic_load_fw.ko

//$(CROSS_COMPILE)strip --strip-debug 裁剪ko，去掉冗余信息，由于Android系统会统一后处理，不会体现在单个模块的mk里，需要加上

3）进入docker，在此makefile目录下敲make

4）最后根据项目不同 动态调整！

三、源MK
