• RADIUSdesk uses the ExtJS toolkit for the GUI
• The version used is the GPL version 7.0 (The Non-GPL version is already at 7.4)
• We assume you have standard install of the Git code of RADIUSdesk.

• Go to this URL: https://www.sencha.com/products/extjs/cmd-download/
• Select under the Installers without JRE Included the LINUX 64-BIT link and download the latest installer.
• As the link states, there is no JRE bundled with the installer, you have to install a JRE on your system for the JRE to work correct.
• Install a JRE on Ubuntu 20.04

sudo apt install default-jre

• Unzip the Sencha Command file

unzip SenchaCmd-7.4.0.39-linux-64-no-jre.zip 
#This is the output
#Archive:  SenchaCmd-7.4.0.39-linux-64-no-jre.zip
#  inflating: SenchaCmd-7.4.0.39-linux-amd64.sh  

• Run the installer shell (using the file which was produced during the unzip)

 ./SenchaCmd-7.4.0.39-linux-amd64.sh
#This might be needed (!=== REPLACE '/home/system' with the user you are logged in as===!)
export PATH=$PATH:/home/system/bin/Sencha/Cmd/7.4.0.39

• Depending if you are on a system with some desktop (like Xfe) or without one, the installer will ask you some questions about the install. Just select the defaults to complete the install.
• After the install, you should be able to run the Sencha command

sencha help

• A git repo with the GPL version of ExtJS 7.0 is here: https://github.com/tremez/extjs-gpl

• We will create a dev area to test our changes and see if they are working.
