Hi everyone, I've graduated and no longer have the VPN environment needed to test this package. So I discard it and anyone is welcome to adopt it for future updates. Thanks for your support!

libxml2.so.2 is required to run this package. The following patch adds the dependency and applies @hacktor 's fix.

I've downloaded the package, but it's not functioning properly. The use of runlevel in line 9 of MotionPro.sh isn't supported in ArchLinux, and the variable var is never utilized. Thus, I've commented them out.

Another issue is that MotionPro doesn't terminate correctly when you close it, preventing relaunch. My solution is simply adding sudo pkill -f MotionPro -9 to the end of 'MotionPro.sh'.

Sorry for the late update after finding the comment notification in my junk email. I have updated the packet using the patch provided by @beekaysee, and thank you for your patch.

In case someone else can no longer connect because it's out-of-date, here's a patch to update it. The patch also removes the libQt5-files since they don't support wayland.
