arm-linux-gnueabihf- ->  aarch64-linux-gnu-

更改编译器出错需更改 ARCH=arm64

export ARCH=arm  ->  export ARCH=arm64

Makefile

# kernel path
KDIR := /home/rksdk/kernel/
obj-m += RF433.o

# export ARCH=arm
# export CROSS_COMPILE=arm-linux-gnueabihf-
# CROSS_COMPILE
export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-

all:
        make -C $(KDIR) modules  M=`pwd`        

.PHONY : clean
clean:
        make -C $(KDIR) modules clean  M=`pwd`
