Won't run on Manjaro Linux

[justin White]

I just got my PnP built for the most part and I'm just getting to setting up the software. I tend to use Manjaro on everything so that's what I stuck on it. I downloaded OpenPnP 2.0 and tried to run ./OpenPnP. It complained about Java so I installed openjre17 (can't remember the exact package name) It no longer throws the Java error but it doesn't start openpnp either. Not getting any errors or anything in the terminal.

Hi,

It seems the Install4J built version of OpenPnP does not include the necessary command line flags to allow use with later Java versions.

I downloaded it and got it to run on my Manjaro box using both OpenJDK 20 (Temurin) and regular OpenJDK 19. To do this you need to modify the OpenPnP script, uncommenting line 6 and changing it to this...

INSTALL4J_ADD_VM_PARAMS="--add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.desktop/java.awt=ALL-UNNAMED --add-opens=java.desktop/java.awt.color=ALL-UNNAMED"

Regards,
Ian

ps. The above hack should work for your openjre17 too.

This hack will get overwritten with every update. I've pinged Jason about this in
https://github.com/openpnp/openpnp/pull/1534
so hopefully it (or something similar) will get added to future builds at some point.

It wasn't working with openjre17 so I checked the repo for openjdk19 (I know nothing about java) and it wasn't in the official repo. Being a new build I realized hadn't enabled AUR yet which I did to check on openjdk19. Then I realized someone actually built an AUR package for OpenPnP in March so I just built that instead. That runs fine and IIRC it doesn't depend on a newer java version anyway. Now onto the next issue

[Jason von Nieda]

Are you running the test branch or the normal branch from https://openpnp.org/downloads/?

If the latter, the changes for newer JDKs has not been merged to that branch yet. Hopefully sorting most of that out today.

For the time being, you might have better luck with https://openpnp.org/test-downloads/

For background:

The JDK 17+ changes have been merged to test, but not to develop. There are a new set of changes that need to be merged to test (today) that will hopefully resolve the last few platform issues, and then we will eventually merge this all to develop.

Thanks,

Jason

Hi Jason.

Dunno about the OP, but the one I tried was the regular develop one. I'm so used to building from source I never even thought to try the test one. Thanks for looking into it.

All the best,
Ian

This is the one I built from the AUR

https://aur.archlinux.org/packages/openpnp

There's also a git version:

https://aur.archlinux.org/packages/openpnp-git

Not really knowing the difference I usually just go for non-git versions. Is there some issue with the version I built?

Gonçalo's PKGBUILD pulls the develop tarball...

source=("OpenPnP-${_pkgver}.tar.gz"::"https://openpnp.s3-us-west-2.amazonaws.com/develop/${_pkgver}/OpenPnP-unix-develop.tar.gz"

Similarly his git version either pulls the default branch (develop I guess) or has a fixed commit id (pkgver=r3506.693671c629). I'm not 100% sure how makepkg handles git sources.

Changes to OpenPnP happen first on the test branch, so if you want the bleeding edge you'll need a test build. The Java >= 17 support should make it from test into develop soon.

When using AUR it's always a good idea to look at the PKGBUILD and see exactly what you're getting. That's in general, not just OpenPnP.

For OpenPnP it's probably better to get the installers from the website rather than relying on Gonçalo to keep his AUR package up to date, though he's doing a good job on that so far I think.

CU,
Ian
