RPi5 - BareBoat Necessities OS - o-chart error

[Mogur]

Good evening folks,

As stated above, running a Raspberry Pi 5 with BareBoat necessities loaded. Runs smooth but falters at the o-charts plug-in.

Open CPN: ver 5.8.4

o-charts plugin (via plugins manager on CPN): ver 2.0.3.1

Compatibility
Active Setting : ubuntu-wx32-arm64:22:04

I have updated catalogue both before and on a separate attempt after to see if i get a different outcome. I am able to install the plugin, however when enabled, no new menu options appear under charts. Upon restart, I receive the error;

'The following plugin has encountered errors during startup:


o-charts


This plugin will be ininstalled. You might want to reinstall it after updating the catalog.'


The log report says the following:

00:59:28.197 ERROR dlunix.cpp:120 Failed to load shared library '/home/user/.local/lib/opencpn/libo-charts_pi.so': libGLEW.so.2.1: cannot open shared object file: No such file or directory


Hoping someone can help me out with this.

As you see libGLEW.so.2.1shared object is missing. This object exists in Debian Bullseye but no longer in Bookworm
I have always said that mixing packages from Ubuntu and Debian makes no sense.
What you could do. My advice: uninstall OpenCPN from PPA and all related plugins and install from bookworm-backports.
https://packages.debian.org/bookworm-backports/opencpn
Howto activate backports: https://wiki.debian.org/Backports

Or take the path via Flatpak

O-charts plugin works for me if I just enable it after installing BBN OS. It’s already there. There was no need to install it from plugin manager.

Also libGLEW is there too.

sudo find / -name libGLEW\*

o-charts plugin (via plugins manager on CPN): ver 2.0.3.1
Compatibility
Active Setting : ubuntu-wx32-arm64:22:04

Then plugin from the catalogue very strange version. Namely libGLEW.so.2.1 is available in Ubuntu 20.04 and no longer in 22.04

It’s libGLEW.so.2.2 in Debian Bookworm.

It seems plugin manager picks up not matching binary for o-chart plugin. (Might be an error in catalog).

Thank you very much for the response and fix. I have it working now.

This bug report has a story for those who may encounter the same issue:

https://github.com/bareboat-necessit...gen/issues/399

It seems to be an issue with OpenCPN catalog after all.
