FAILED: ninja: ‘device/khadas/kvim3-kernel/4.9/kvim3.dtb’, needed by ‘out/target/product/kvim3/dt.img’, missing and no known rule to make it

你好，我在编译的过程中遇到了该问题，我们查看了您的git仓库，发现并没有提交kvim3-kernel相关的内容，仅有kvim3l-kernel的内容。我们使用khadas-vim3-r-32bit Branch进行编译，在 **android_device_khadas**仓库中并未找到相关内容。 非常着急

kvim3-kernel这个是编译kernel生成的
你将out目录删除，新建build.sh脚本内容如下

#!/bin/bash

PROJECT_PATH=`pwd`
echo $PROJECT_PATH
	
#build uboot
if [ "$1" == 'u' ] || [ "$1" == 'n' ]; then	
	echo "build uboot"
	cd bootloader/uboot
if [ "$2" == 'n' ] || [ "$1" == 'n' ]; then
	#make distclean
	#make clean	
	echo "build uboot n"
fi	
	./mk kvim3 --vab 2>&1 | tee ../../build_vim3_11_uboot.log
	cp build/u-boot.bin ../../device/khadas/kvim3/bootloader.img
	cp build/u-boot.bin.sd.bin ../../device/khadas/kvim3/upgrade/
	cp build/u-boot.bin.usb.* ../../device/khadas/kvim3/upgrade/
	cd -
fi

#build kernel
if [ "$1" == 'k' ] || [ "$1" == 'n' ]; then
	echo "build kernel"
if [ "$2" == 'n' ] || [ "$1" == 'n' ]; then
	make distclean
	#make clean
fi	
	./mk kvim3 -v 4.9 -j50 2>&1 | tee build_vim3_11_kernel.log
fi

#build android
if [ "$1" == 'a' ] || [ "$1" == 'n' ]; then
	echo "build android"
	cd ${PROJECT_PATH}
if [ "$2" == 'n' ] || [ "$1" == 'n' ]; then
	#make clean
	#rm -rf out/
	cd common
	make clean
	make mrproper
	make distclean
	cd -
fi	 
	#export ALLOW_MISSING_DEPENDENCIES=true
	export BOARD_COMPILE_ATV=false
	export BOARD_COMPILE_CTS=false
	. build/envsetup.sh
	lunch kvim3-userdebug
	make installclean
	make -j80  2>&1 | tee build_vim3_11_android.log
	#make otapackage -j80 2>&1 | tee build_vim3_11_ota.log
	#xz -zk out/target/product/kvim3/aml_upgrade_package.img
fi

使用./build.sh，编译失败的话将生成build_vim3_11_uboot.log，build_vim3_11_kernel.log，build_vim3_11_android.log上传给我看看

小哥，我检查了下Log,还是应为缺少一些必要的库，如bc、rsync，当前kernel已经顺利编译成功了。谢谢，幸苦。
