你倒数第二张图表示已成功同步代码了，你最后一张执行那命令是什么意思？
请问，编译安卓10需要的内存是多少？16G内存是否可以?>
已经全部编译成功，但在目录 **rockdev/Image-aosp_arm下没有找到1

这样文件，到在Image-rk3399_Android10有文件但也是不全的！
请问这种情况是否正常?
怎么不全？？？？？？？？？？？？？？、？
没有update.img文件，在文件内没看到此文件
在SDK根目录下。。。。。。。。。。。。。
编译安卓7的时候出现以下错误，该如何解决.

jack不支持多用户同时编译，你是不是同时编译android 7.0和android 10.0啦？
其实你遇到的这些问题，都可自行在网上找到答案。
明白了！我编译的时候不小心输入个android10的编译命令
执行./mkimage.sh前要先执行下面命令：
source build/envsetup.sh
lunch rk3399_Android10-userdebug
有编译过了的，不编译source build/envsetup.sh
lunch rk3399_Android10-userdebug这连个后面是编译不过的
你是编译android 9.0代码吗？android 7.0，android 9.0，android 10.0你是怎么管理代码的？分为三个目录吗？
要不你删掉out目录重新编译看看。
android7/9/10是分开单独的unbuntu系统下的
第一个是android 7.1的固件，第二个是android 9.0的固件。估计你之前有在这个代码目录编译过android 7.1
