Pre-requisites for HTMLRenderer in 17.1 on Linux

[AndyS|Dyalog]

This post is a little previous as we have not yet released 17.1. However, the documentation will refer to this post so that we can more easily keep the list of pre-reqs up to date.

This post lists the pre-reqs which are needed in order to use the HTMLRenderer for various versions of commonly used distributions. The pre-reqs for installing 17.1 on Linux can be found here.

If you try to create an HTMLRenderer object and get a LIMIT ERROR, the most likely causes are:

ENABLE_CEF has been set to 0
You are missing pre-req filesets
You are not running in a supported environment (perhaps X has not been configured
properly)

There is more information in the HTMLRenderer User Guide - the technical overview. It also explains how to determine if you have missing pre-reqs.

Below is a list of distributions/versions which we have tested, as of 2019-05-15, with latest filesets installed.

We have included the commands needed to install the pre-reqs, but remember that it will need to be run with root privileges - either su beforehand or run sudo command. In some cases there are other commands that could be used and you can always use the distribution's GUI-based software management tool instead.

Debian 8.2, 9.8, 9.9  : no pre-reqs needed
Fedora 29, 30         : dnf install libXScrnSaver
