WSL2 - AOSP 11 模拟器无法启动，因为无法初始化 Qt 平台插件 (xcb)

Question

我正在尝试在我的 x86-64 机器（Intel cpu）上的 WSL2 Ubuntu 20 上为 android 11 构建 AOSP，构建（用于 aosp_arm64-eng）成功，但模拟器无法在我的 WSL2 上运行。

我尝试应用我在网上找到的修复程序，但没有任何帮助（修改环境变量、安装库等。（我还没有尝试过 LD_PRELOAD 技巧） 我认为它试图在 repo 中使用 Qt）。

（另见："Failed to load platform plugin "xcb" " while launching qt5 app on linux without qt installed）

流程是：

$ repo init -u https://android.googlesource.com/platform/manifest -b android-11.0.0_r50
$ repo sync
$ source build/envsetup.sh
$ lunch aosp_arm64-eng
$ m -j4
[build was successfull]

Answer 1

假设 WSL2，只需尝试在系统范围内安装它：

sudo apt-get install libx11-xcb1

或任何其他可能提供的libqxcb.so。

---

直接在 Windows 和 HAXM 上运行时，整体性能可能会更好。
我只是想知道，WSL2 将如何处理 KVM，因为它本身可能是一个仿真。
在 WSL2 上构建不是问题，但在没有 KVM 的情况下运行模拟器是： https://boxofcables.dev/kvm-optimized-custom-kernel-wsl2-2022/

Answer 2

好吧，最终我在远程 ssh 连接到 linux 服务器上尝试了它，并得到了类似的错误。

问题是模拟器需要一个图形环境。因此，要么使用获取构建输出图像并在 Android Studio 中使用它，要么使用 vncserver（和客户端）从 GUI 环境连接到它。
