Chart-plugin failed to install on Victron Cerbo-GX

[ghrlgv]

I'm using the latest Venus OS Large image version 3.66 with SignalK version 2.13.5 and node version 20.18.2. SignalK default install home on the Cerbo-GX is /data/conf/signalk.

Logfile presents the following info: (EDIT: legibility)

The error implies that VenusOS does not have all the dependencies needed for compilingsqlite3 support. The plugin needs that for supporting chart data in MBTiles format.

There are different potential strategies for solving this problem, with the easiest first:

• change the plugin so that sqlite3 is an optional dependendy - this would allow using other chart types, but not mbtiles
• add the plugin to a future version of VenusOS image, so that it is prebuilt and installation is not on demand
• adding the needed dependencies to VenusOS

Thanks for the prompt response. I'll try to update VenusOS with all the dependencies.

Solved. Now able to install and use the signalK chart-plugin.

Actions taken (suitable for a Victron Cerbo-GX mk2 device):

Remote login into your device (ssh may need to be enabled first using the GUI):
# ssh root@<ip-address>

Mount the rootfs as read/write:
# mount -o remount,rw /

Expand the available space in the partition:
# /opt/victronenergy/swupdate-scripts/resize2fs.sh

NB. Make the modification semi permanent by adding “mount -o remount,rw /“ to /data/rc.local.

Update the venusOS package local repository:
# opkg update

Install python PIP:
# opkg install python3-pip

That’s it, all the chart-plugin dependencies are now met. Try installing the chart-plugin using the SignalK -> AppStore menu.

BTW. Be patient. The plugin compiles some the required executables and the Cerbo-GX devices is not that fast in doing so. On my device it took about 15min.

Restart the signalK server after the chart-plugin completes.
Then configure the plugin and enjoy.

Nice! I added a note about this in the README 194e40c
