nanopi m4模块编译错误

wkangk

make -C /lib/modules/4.4.167/build M=/home/wkangk/work/pcf8591 modules
make[1]: *** /lib/modules/4.4.167/build: No such file or directory.  Stop.
Makefile:10: recipe for target 'kernel_modules' failed
make: *** [kernel_modules] Error 2


为什么/lib/modules/4.4.167/build 这个目录下什么都没有, 该怎么解决这个问题

我的 Makefile

1. KERNELDIR ?=/lib/modules/$(shell uname -r)/build
   
2. 
   
3. CURRENT_PATH := $(shell pwd)
   
4. 
   
5. obj-m := pcf8591.o
   
6. 
   
7. build: kernel_modules
   
8. 
   
9. kernel_modules:
   
10.         $(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) modules
    
11.        
    
12. clean:
    
13.         $(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) clean
