Re: Phoebus on ARM64

["Kasemir, Kay via Tech-talk" <tech-talk at aps.anl.gov>]

The JavaFX graphics lib doesn’t always include binaries for linux-aarch64.

For example, version 21.0.7 only has ..-linux.jar

https://repo1.maven.org/maven2/org/openjfx/javafx-base/21.0.7/

Version 23 does include ..-linux-aarch64.jar,

https://repo1.maven.org/maven2/org/openjfx/javafx-base/23/

Fundamentally you pick the version in the phoebus/pom.xml file by changing this line:

    <openjfx.version>21.0.7</openjfx.version>

.. but changing the JFX version might have other side effects.

In general, it’s probably not the best idea to include the display (and alarm server, archive, …) in the IOC.

EPICS is a distributed system where the IOCs perform the sampling and certain control aspects, displays then run on client machines and so on.

Has there been any thought of porting the Phoebus CSS software to ARM64?

 

I have a little BeagleBoard AI-64 system running Linux and XFCE that I’d like to get into a stand-alone test system.  I’ve got the IOC handled, all the drivers managed, and I’m down to display software.

 

Building Phoebus fails miserably.
