REW Java version for RaspberryPi OS 32bit newest "Bookworm"

[jesperlykke]

Hi here...

(I used to have REW running on the old Raspberry 32bit "Buster" version, but I need a newer version for other stuff on my RPI toolbox.)... Therefore ::

I'm trying to install the java 8 package, but it's not "possible" on the Bookworm release (32bit).
Is there another version that can run REW.

I'm trying to install REW so to mainly use the "signal/tone/sine" generator for sending signal/tones to my balanced DAC for measurements.
I'm using VNC server to see the RPI desktop from my laptop.

(If it's matter, I only need the signal/tone generator part of REW for now)

Any help appreciated / Jesper.

You can use newer JDK, look at e.g. https://www.avnirvana.com/threads/rew-linux-installation.6711/ .

Thanks @phofman ...

First I installed the 64bit version of Bookworm.
Then the JDK17 from the Bookworm repo.

I then installed the temurin-8-jdk. No change to java with update-alternatives or like.

lykke@superplayer:~ $ java --version
openjdk 17.0.16 2025-07-15
OpenJDK Runtime Environment (build 17.0.16+8-Debian-1deb12u1)
OpenJDK 64-Bit Server VM (build 17.0.16+8-Debian-1deb12u1, mixed mode, sharing)

REW did first install after I installed the temurin-8-jdk.

Did not do much testing, but I can see that REW is running faster on the VNC with the 64bit distro, than with the 32bit one.
