Hi,
I am trying to run this make interface command and get the libQt5WebEngineCore.so.5.15.2 not found the error. Not sure what is the issue. Tried several things. The Vircadia build is in the root and at this location /vircadia/build and using Ubuntu 18.04
Using root to run this and stuck at this. Please help. thanks.

It is not not finding libQt5WebEngineCore.so.5.15.2, it is not finding libevent-2.1.so.6, libwebpmux.so.3, libwebpdemux.so.2, libwebp.so.6, libXss.so.1, and libsnappy.so.1.
These libraries should have been installed by vircadia-builder. What command are you starting vircadia-builder with? And are you actually using Ubuntu 18.04, or are you using another distribution with the Ubuntu 18.04 package base?

thanks so much Julian for your time.

This is an issue with the build instructions. vircadia-builder has nothing to do with this. vircadia-builder is a build script that is supposed to do a lot of this automatically. It should also work on Debian Buster.
Also keep in mind that you only need to compile Interface yourself to test development code. There is AppImages available for download.

It identifies itself as Ubuntu 18.04. If you don't know more than I do, this isn't Debian 10, but Ubuntu 18.04.
