Did you install with?
$ flatpak install --user http://opencpn.duckdns.org/opencpn-beta/opencpn.flatpakref
Normally one would expect oeserverd under:
/home/{USER}/.var/app/org.opencpn.OpenCPN/bin/oeserverd
When you type flatpak list
the installation is supposed to be found under user, not under system
Thanks for your reply. Looks like I didn't have the beta. So, to be able to answer properly I wiped everything including manual file deletes where necessary and then installed the beta (yes as user). The result is exactly the same. Your response is a bit puzzling as the binary helper is not installed by OpenCPN. It is only installed with the plugin. The oeservd file will appear where you say if you install the plugin from the repository. This is not the problem I am trying to solve. The problem I have is to get the binary helper in an appropriate location when installing the plugin with flatpak. This is the problem I am trying to solve. I am doing this so that I can use the approach on other plugins that aren't yet available in the repository. Thanks Greg
Greg... This build mode for a flatpak plugin has not really been tested at all. All production builds are using a CI process to package tarballs, which are then installed by OCPN at run-time. But lets take a look... From the console output of your "install" step, where exactly is the oeserverd being installed? Dave
Hi Dave, thanks for the reply. Yes I guessed that that was the case as it is difficult even to build and install the tar.gz unless you use the CI process. In doing this I was hoping to be able to advance the cause even though I don't have a lot of experience in build systems. To your question:
After install, the follwing files are found in /home/greg/.local/share/flatpak/runtime/org.opencpn.OpenCPN.Plugin.oesenc/x86_64/master/f758f5ff57fd4fd2e743fb1c07d15abe7eb54e5a83ea1049dbd4baeba3c69169/files/bin/: libsgllnx64-2.29.02.so oeserverd oeserverd.prog
I hope that answers your question Greg
I have found a solution. I am not sure if it is the best solution, but it does look right to me. I started by checking path in use with flatpak (from the log) as follows:
MESSAGE pluginmanager.cpp:1047 Using PATH: /home/greg/.var/app/org.opencpn.OpenCPN/bin /app/extensions/bin /app/bin /home/greg/.var/app/org.opencpn.OpenCPN/bin /app/extensions/bin /app/bin /app/bin /usr/bin
I found by executing the following command that I could see how the overlays are mapped by flatpak: flatpak run --devel --command=sh --system-talk-name=org.freedesktop.login1 / org.opencpn.OpenCPN The binaries were found at /app/extensions/oesenc/bin. Clearly this is not in the path being searched.
I then changed line 30 in the .yaml file by add ";bin" to the end as follows: 27 add-extensions: 28 org.opencpn.OpenCPN.Plugin: 29 directory: extensions 30 merge-dirs: lib/opencpn;share/opencpn/plugins;share/locale;bin 31 subdirectories: true 32 no-autodownload: true 33 autodelete: false
This results in links being placed in /app/extensions/bin which is in the search path.
/app/extensions/bin/libsgllnx64-2.29.02.so -> /app/extensions/oesenc/bin/libsgllnx64-2.29.02.so /app/extensions/bin/oeserverd -> /app/extensions/oesenc/bin/oeserverd /app/extensions/bin/oeserverd.prog -> /app/extensions/oesenc/bin/oeserverd.prog
Now, after wiping and reinstalling OpenCPN and oesenc_pi, everything works as it should.
I would be happy to create a PR if you deem this appropriate. If so, should I do it through opencpn/OpenCPN or leamas/OpenCPN?
Greg
Closing as I have proposed a solution. Have raised this PR #https://github.com/leamas/OpenCPN/pull/5#issue-428962650
I really appreciate the enormous amount of work that is put into this, and like the direction that you are going using Flatpaks.
I am trying to setup OCPN on a Debian Buster machine.. So I thought I would have a go at preparing some flatpak plugins following Alec Leamas's instructions. I decided to start with S63. After quite a bit of fiddling I am able to package it OK, but ran into problems finding the helper file OCPNsenc. Assuming that I had done something wrong patching the code I decided to implement oesenc in a clean installation to see how it worked as both builds put the binary in a similar location.
The result was identical behaviour. That is, the helper oeserverd file was not found. If you install using the downloaded tar.gz file, the binary is installed in a location that can be found. However, installing from a flatpak this is not the case. The problem shows up when trying to create a fingerprint file.
The error message is "Error Creating Fingerprint file check OpenCpn Log file".
The location of oeserverd is: .local/share/flatpak/runtime/org.opencpn.OpenCPN.Plugin.oesenc/x86_64/master/82dd699196b56c5684d9fc0d06167d53dc5f125077faafbbfa3596ce7e8b4774/files/bin/oeserverd
In the flatpak build directory it is in app/files/bin/.
The steps were: Clean out any OCPN files from .var and .local and check that there are no others anywher else.

It is quite possible that I have done something wrong, but I think I have followed all of the instructions fully. Thanks and Regards
