UGS does not compile on RPI: 'Node.js' '404 from server' #1505
Comments
|
We are using maven to build the node application which can't be built on ARM-based systems. So you need to disable the pendant module from the build: If you just want to run UGS on a RasberryPI I would recommend you use the prebuilt image instead of compiling it: You can find more instructions for RPi here: https://github.com/winder/Universal-G-Code-Sender/wiki/Raspberry-Pi |

Joacim,
Thanks for the reply, that does work. I have version 202001202 installed.
Although at idle the java process sits at exactly 100% cpu, is that
expected?
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
COMMAND
1116 pi 20 0 591684 209060 41620 S 101.0 23.4 9:51.36 java
Somebody might also be interested that it starts with this message:
OpenJDK Server VM warning: Options -Xverify:none and -noverify were
deprecated in JDK 13 and will likely be removed in a future release.
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by
org.netbeans.ProxyURLStreamHandlerFactory
(file:/home/pi/ugsplatform-pi/platform/lib/boot.jar) to field
java.net.URL.handler
WARNING: Please consider reporting this to the maintainers of
org.netbeans.ProxyURLStreamHandlerFactory
WARNING: Use --illegal-access=warn to enable warnings of further illegal
reflective access operations
WARNING: All illegal access operations will be denied in a future release
Finally, somebody may want to know that I installed this code based on this
video: https://www.youtube.com/watch?v=u35L0jGCqFc. If this method no
longer works, maybe you should put a comment in the script stating this
doesn't work on RPI? That might stop other users like myself contacting
your support.
However I have it working, so look forward to trying it out!
Regards,
Ben
PS, still sitting on 100% CPU when idle...

Could you have a look in the log file: I know there has been problems with the visualizer on RPi and there might be a bunch of errors being spewed in the log. |

Certainly. Running from cold we have again 100% CPU:

The new log file from /home/pi/.ugsplatform/2.0.7-SNAPSHOT/dev/var/log is
attached.
I hope you find this useful.

Attachments from emails will not be added to github, you would need to add it through the web page. |

Attachment added from Website. Thanks Breiler. |

That didn't give any clues other than that the visualizer couldn't be properly started. Try closing that window inside of UGS if it is open and restart. |
|
I've closed all windows within the app. Back to a blank screen just
showing menu options and 'No file loaded' in the footer.
The CPU is still 100%.
After restart the CPU again settles at 100%.
If I look at threads rather than processes, the Java shows just one thread
causing the load:
top - 18:22:17 up 1:36, 4 users, load average: 1.00, 1.08, 0.93

Thanks! If you feel like experimenting you can try installing an older version of java (the newer ones does not work with netbeans). Then download UGS without a bundled Java: https://ugs.jfrog.io/ugs/UGS/v2.0.7/ugs-platform-app.zip You can verify that it uses the Java 8 if you open the "About" dialog. |
|
Sounds like fun.
Before
$ java --version
openjdk 11.0.9.1 2020-11-04
OpenJDK Runtime Environment (build 11.0.9.1+1-post-Raspbian-1deb10u2)
OpenJDK Server VM (build 11.0.9.1+1-post-Raspbian-1deb10u2, mixed mode)
After
$ java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-8u212-b01-1+rpi1-b01)
OpenJDK Client VM (build 25.212-b01, mixed mode)
I found the --jdkhome switch on your program, and pointed it at 1.8.
The CPU is now on 0.3% as I look at it now. Problem fixed.
I now have another problem when I open up a file, I get the error:
No GLDrawableFactory available for profile: GL4bc
I've not connected it to my 3018 yet, as I've blown the PCB and am waiting
for a replacement.
The only thing it is, is a little slow. I'm using an RPI 3. I think I may
need an RPI 4. But that's my problem.
Thanks!

I'll consider changing the default JRE to 1.8 for RPi, thanks for debugging. |

Glad to help. If you want me to test any other versions please ask.

I made a version that bundles an an older JDK, if you have the time I'd appreciate if you could give it a try: |

That version of Java might have another issue. My RPi has a mounted Google
Drive:
$ df -T /home/pi/gdrive
Filesystem Type 1K-blocks Used Available Use% Mounted on
gdrive: fuse.rclone 15728640 4250184 2339348 65% /home/pi/gdrive
All other apps can read this drive, accept that Java. It just shows an
empty drive. The 1.8 version worked here.

When compelling the latest version on Raspberry PI (Raspberry Pi 3 Model B Plus Rev 1.3, Debian 10.7) I get this error:

Any help welcome?
