These instructions are for J901 beta and show how to:
- get base system from a zip or tar.gz release package
- handle security issues - allow downloaded programs to run
- update base, all addons, and Jqt ide
- create desktop launch icons for J user interfaces: jconsole, JHS, and Jqt
- run and play a bit with each of the user interfaces
- update JE (J Engine) with bug fixes and advanced hardware support
Following assumes you are installing J in your home folder. Installing in a protected folder requires extra privileges at one or more steps to enable writes and is for advanced users. Examples use Fred as your home folder.
J901 installs have a JE (J Engine) that runs on basic hardware (not an advanced hardware version). An initial install can be updated to an advanced hardware version (avx or avx2) if the hardware supports it.
J901 for Android is available here J901 install.
