Virtuoso installation stuck on "VAD Sticker vad_dav.xml creation" on 2nd attempt

Question

I've been attempting to install virtuoso-opensource as per the README here: https://github.com/openlink/virtuoso-opensource

The first time I ran make, it breezed passed "VAD Sticker vad_dav.xml creation" to "Starting Virtuoso Server" and then complained netstat: command not found.

I installed netstat via sudo apt-get install net-tools, ran make again and now it's always stuck on "VAD Sticker vad_dav.xml creation" even after starting from scratch after deleting the repo folder and re-cloning it again. make install gets stuck at the same point.

Does anyone have any ideas as to how to get past this?

I'm running Ubuntu Server 20.04.1 LTS on an AWS EC2 instance.

Answer 1

I'll note the requirement for netstat to build VADs.

By far the most common cause of hang at that stage is a stagnant virtuoso pid lurking.

pkill virtuoso and run make again.
