我一直在按照说明操作(https://github.com/android-rpi/device_arpi_rpi4/blob/arpi-11/README)用于为Raspberry Pi 4构建Android 11，并且在执行make时遇到了问题。在我的世界里，我无法弄清楚我错过了什么或做错了什么。我试图解决的实际错误是什么？我的假设是缺少依赖关系。

此特定错误的问题与虚拟机没有足够的RAM/swap有关。该构建需要16Gb的RAM/交换，而虚拟机远远不够。扩展交换文件解决了这个问题。现在我还有其他的问题要解决，但那是一个不同的帖子。
- 尝试重新同步代码库
repo sync --force-sync - 然后尝试重新构建
source build/envsetup.sh && lunch rpi4-eng && make ramdisk systemimage vendorimage
以下是在我的案例中安装的所有构建工具：sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig kpartx python-mako gcc-arm-linux-gnueabihf libssl-dev
在WSL2下，内存可能不够。谷歌搜索一种增加内存的方法。而且，我的回购出现了问题，然后我运行了以下代码
cd .repo/repo && git pull && cd - && repo sync
