AnolisOS 8.4 ANCK内核，8.6也一样。
crun开发者的回复：
I am fine to add a workaround, but I'd like to understand what is going on.
What system are you running?
It seems your kernel has support for pidfd_open but not for pidfd_send_signal.
pidfd_open was added to Linux v5.3 while pidfd_send_signal to v5.1
是否是ANCK内核添加了5.3的特性又没有添加5.1的特性呢？

系统安装的有libQt5Gui.so.5，
[root@Longxi ~]# locate libQt5Gui.so.5
/usr/lib64/libQt5Gui.so.5
/usr/lib64/libQt5Gui.so.5.15
/usr/lib64/libQt5Gui.so.5.15.2

qt5-qtbase-gui-5.15.2-3.an8.x86_64
qt5-qtbase-common-5.15.2-3.an8.noarch
希望能更新安装方法或能给点建议，谢谢！
