DPScope - seeking help to execute on Raspberry Pi board running RasPiOS (Debian 12 Bookworm)

[DeeJay]

Greetings Sam.

Google pointed me to your DPScope project repo. I was pleased to learn that there might be a cross-platform way of accessing my usb scope that did not rely on MSWindows.

But I am not a java user, so I am having trouble understanding what I need to do to run the project on my Raspberry Pi board running RasPiOS (Debian 12 Bookworm).

This is what I have tried so far.

This is my java version -

david@rp54bw64full0512:~/Projects/sjfom/DPScope $ java -version
openjdk version "17.0.10" 2024-01-16
OpenJDK Runtime Environment (build 17.0.10+7-Debian-1deb12u1)
OpenJDK 64-Bit Server VM (build 17.0.10+7-Debian-1deb12u1, mixed mode)
david@rp54bw64full0512:~/Projects/sjfom/DPScope $ 

I have cloned this github repository -

First attempt was to simply run the .jar file -

david@rp54bw64full0512:~/Projects/sjfom/DPScope $ java -jar DPScope.jar 
Error: Could not find or load main class com.dpscope.MainScope
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application
david@rp54bw64full0512:~/Projects/sjfom/DPScope $ 

That seemed to be faulting with the absence of javafx so I visited
https://openjfx.io/openjfx-docs/#install-javafx

Installed javafx-sdk-22 -

david@rp54bw64full0512:~/Projects/sjfom/javafx-sdk-22/lib $ 

Exported an environment variable for that library -

david@rp54bw64full0512:~/Projects/sjfom/DPScope $ export PATH_TO_FX=/home/david/Projects/sjfom/javafx-sdk-22/lib
david@rp54bw64full0512:~/Projects/sjfom/DPScope $ echo $PATH_TO_FX
/home/david/Projects/sjfom/javafx-sdk-22/lib
david@rp54bw64full0512:~/Projects/sjfom/DPScope $ 

Reran the .jar with arguments supplied to java as in the javafx Getting Started -

david@rp54bw64full0512:~/Projects/sjfom/DPScope $ java --module-path $PATH_TO_FX --add-modules javafx.controls -jar DPScope.jar

Exception running application com.dpscope.MainScope
david@rp54bw64full0512:~/Projects/sjfom/DPScope $ 

Perhaps that has solved the javafx issue, but revealed another.

Some Googleing suggests that

Caused by: java.lang.NoClassDefFoundError: com/sun/javafx/css/StyleConverterImpl

may be related to jfeonix? But I can't find any pointers to resolving that.

Could you provide any guidance, please? Thanks for reading this far.
