Quote:But it seems there are some things in the MoodePi OS setup that prevent it from loading the current Linux REW and/or the necessary JRE. I’m just not smart enough to identify them.

Quote:But if the MoodePI OS could be configured such that we can install the latest JRE, we could just install the latest REW via SSH and run it that way on an as needed basis.

Sorry, it *is* configured to install recent Java (openjdk-11-jre).

The thing is, REW doesn't want a recent version (which leads to it trying to install the AMD64 JVM). As the above posts about the REW Linux Installer pointed out, REW wants Java 8. One needs only the JRE so let's get the openJDK version...

Starting Installer ...

This will install REW on your computer.

OK [o, Enter], Cancel [c]

Where I had previously downloaded the REW installer script and marked it as executable.

I don't see a problem.

Of course, you'll now have the challenge of input and display once you get it running. Since the REW GUI creates an Xwindow, you could run it remotely from some other host running an Xserver, but that's outside the scope of moOde.

I still think an RPi4B running RaspbiOS Desktop is a better approach.

ETA - In response to Tim's last post, moOde 8 is built on RaspiOS Bullseye but I just confirmed the same procedure works on a moOde 7.6.1 player which is built on RaspiOS Buster.

RE: Ability to house REW - Marrahm - 02-22-2022

Tim, it is not easily installable on the new bullseye. I have tried with both the 32 and 64 bit kernels after doing a clean install with update/upgrade. Situation is the same:

-installing “default” open Java works fine, but it installs the newest version, which REW does not seem to like b/c it still tries to install its internal v8 JRE

-Internal JRE still fails after checking the installed JRE status, unpacking the internal JRE and posting following error:
“The architecture or bitness (32/64) of the bundled JVM might not match your machine.”

Since this seems like an REW issue and not a Moode issue, I’ll see what that team says about it. If they used the current JRE, that seems like it would solve everything, but I’m sure thats easier said than done. Thanks for taking a look at it.

I have to think the internal JRE is 32B and not 64, so I’ll try that next. The only 64b v8 JRE that I could find (on OpenJDK) will not load either as it has a list of dependencies that cannot be resolved, presumably b/c they don’t exist for bullseye yet.

Mike

You can choose either the default 32-bit kernel or the optional 64-bit kernel in moOde 7.6.1 but in either case the root filesystem is 32-bit. Period.

ETA: I think you'd get where you want to go a lot faster if you started posting to the official REW forum or to diyaudio.com.

Kent,

this is on the new Bullseye OS for moode 8? If so, did you install any other repositories from stock? When I tried to install open8 JRE it was unable to find it in the bullseye reps.

@Marrahm

Fresh out of the box, a virgin 32-bit RaspiOS Bullseye with Desktop running on a Pi400:

Code:
pi@raspberrypi:~ $ apt-cache search openjdk-8-jre

libreoffice - office productivity suite (metapackage)

openjdk-8-jre - OpenJDK Java runtime, using Hotspot JIT

openjdk-8-jre-headless - OpenJDK Java runtime, using Hotspot JIT (headless)

openjdk-8-jre-zero - Alternative JVM for OpenJDK, using Zero/Shark

This thread is very getting far afield of moOde and moOde issues. The official REW forum is the place for questions about REW on Raspberry Pi OS with RPi hardware.

Kent
