Building OpenNebula from source on Ubuntu 20.04

Hi All,

I am building OpenNebula from source on Ubuntu 20.04. This is the documentation that I am following - However, I am not able to run scons to compile OpenNebula. The error I am getting is in the current results section below.

Versions of the related components and OS (frontend, hypervisors, VMs):
OS - Ubuntu 20.04 (Canonical-Ubuntu-20.04-2020.10.14-0)
The machine is a Bare Metal running on Oracle Cloud (BM.DenseIO2.52).

Steps to reproduce:
Spin up a BM.DenseIO2.52 compute instance with Ubuntu 20.04 image on Oracle Cloud. Install a VNC server and a desktop environment to connect to the machine using VNC Viewer (This step is optional). Git clone the repo. Download all the libraries required and mentioned here for Ubuntu 20.04 - Change to the directory “one”. And then run scons.

Current results:

Error searching for xmlrpc-c libraries. Please check this things:

  • You have installed development libraries for xmlrpc-c.One way to check
    this is calling xmlrpc-c-config that is provided with the development
  • Check that the version of xmlrpc-c is at least 1.06. You can do this also
    $ xmlrpc-c-config --version
  • If all this requirements are already met please send log
    TypeError: unsupported operand type(s) for +: ‘NoneType’ and ‘str’:

Expected results:
No error

Appreciate your help. Thanks!
