【应用开发】核心板3588运行QT异常，如何解决？

Question

首先在Firefly开发板上烧写的是官方提供的统一固件

操作系统是ubuntu20.04

qt5-default、qtcreator安装都是正常的

在命令行下直接运行qtcreator时，运行不了，直接报错了

firefly@firefly:~$ qtcreator
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
arm_release_ver of this libmali is 'g6p0-01eac0', rk_so_ver is '5'.
ConnectionServer error: "QLocalSocket: Remote closed" "/tmp/QtCreator-PbOtcS/ClangBackEnd-46368"
Segmentation fault (core dumped)

但是用sudo时却能显示出qt的界面，但命令行窗口输出也同样出错了

firefly@firefly:~$ sudo qtcreator
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
arm_release_ver of this libmali is 'g6p0-01eac0', rk_so_ver is '5'.
error: XDG_RUNTIME_DIR not set in the environment.
QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

尝试执行下面语句，发现还是解决不了问题

# wayland协议
sudo apt install qtwayland5
export QT_QPA_PLATFORM=wayland

有朋友知道这该如何解决吗？

虽然不知道具体是啥原因，但是使用 apt-get install qtwayland5-examples 却解决问题了，可能是自动下载了之前缺少的东西，然后才能正常的运行QT，奇奇怪怪。
