编译kernel的时候发生以上错误。
解决办法如下：
ricks@ubuntu:~/share/project/ql-ol-sdk$ cd ql-ol-kernel/ ricks@ubuntu:~/share/project/ql-ol-sdk/ql-ol-kernel$ make mrproper arch/arm/boot/dts/Makefile:525: warning: overriding commands for target `dtbs' arch/arm/boot/dts/Makefile:525: warning: ignoring old commands for target `dtbs' CLEAN scripts/basic CLEAN scripts/kconfig CLEAN include/config include/generated
make clean 和 make mrproper的区别请参考 https://www.cnblogs.com/ricks/articles/9400334.html
