oeSENC_PI for OpenCPN5 on Raspberry Pi

[bdbcat]

Hello Pi users....


An intermittent fault in oesenc_pi for ARMHF architectures on OpenCPN Version 5 has been found and corrected.
An update to Version 2.9.1526 is now available in the OpenCPN PPA.


Feedback is always appreciated.
Thanks
Dave

Hi,

Dave, thanks.

I´ll try it in the afternoon and give a feedback.

Regards

Thanks, I shall try it shortly!

Dave or anyone Linux educator...
As you may know I'm a native Win user.
On my pi oeSENC is "spreading" files around out of my control so both oeserverd and libsglarmhf32-2.30.0.0.so is hard to find for O and oesenc itself. Possible due to my build history.
Even after I have tried to clean the history by deleting all build folders and run a new cmake for O and all my plugins. (And all projects in my repository are rebased to origin.)
There seems to be more file destinations data saved in the system. So my question:
How do I clean the history in Debian, if possible?

Here is where oesenc is saved and a runtime error:

oeSENC:

Håkan,

not exactly sure what you are after but:

To erase a complete compilatiion of OpenCPN (located in /usr/local/src/opencpn) including the source code, tou may use these steps (<username> is your local username):


rm -r /home/<username>/.opencpn
sudo find /usr/local/share -name "opencpn*" -exec rm -r {} \;
sudo rm -r /usr/local/lib/opencpn
sudo rm -r /usr/localbin/opencpn
sudo rm -r /usr/local/src/OpenCPN


This will remove everything related to OpenCPN.
The above lines will also tell you all the locations where OpenCPN keep it files. Note that if the system is installed using e.g PPA, you use the same paths but exclude the '../local..' part of the path.
Hope this helps!

Hakan...


Your local builds of oeSENC by default land in /usr/local.
Installs from PPA land in /usr.
linux loader tries to satisfy link requirements looking in /usr/local first, and then /usr second.


If you want to test a PPA plugin, you should simply:

$sudo rm /usr/local/lib/opencpn/lib*

That will cause linker to go to /us/lib/opencpn/ for the plugins, and all required parts. Then all should be well.


This problem only occurs if you build locally. Casual users will not be affected.

Dave..

I've never used a PPA on this Pi.
If you see the make report from my Pi above you'll see nothing is installed in /local/
I'm using latest Git.
Thanks/Håkan

Brilliant, keep up the good work, just bought a Pi Although not for navigation (yet) but exploring those options as well. Once feeling confident enough with the system, I'll duplicate the charts from my Tab A, as allowed by o-charts.

[bdbcat]

Hakan...
Please show logfile for error run.


Thanks
Dave

[Hakan]

Dave..
Log attached but I think I've to clean up as of Lennarts advice. (Thanks!)


oeserverd, opencpn and more are present is several locations. (But nothing in any /local/


Thanks for your time

Hi Dave!


Sorted! This has corrected my issues completely, thank you!



Your support is very much appreciated,

My plan is to run a pi on a "big screen" below decks and a self contained pi with touchscreen at the helm. I have a 7" capacitive touchscreen, I am thinking about a 10" touchscreen though for the helm, as 7" is a bit too small.


I have a 17" LCD panel from an old laptop, with an HDMI -> LVDS adaptor ... the whole system is going to cost me less than the cables would have cost for the Raymarine plotter I had bought!

Hi,

Dave, tested the new plugin-version. Works.

Thanks

Dave..
To continue this where I'm obstinate enough to build oeSENC_pi on my local repository. It may be someone else would get the same idea.
So I've removed everything concerning opencpn and related plugins in /usr/ and underlying directories.
/build directories for O and oesenc are renewed so both are built from scratch and using fresh clones for each local repository.
The file locations after that as of this list:

pi@raspberrypi:~/builds/oesenc_pi/build $ find /usr/ -name  "opencpn"
/usr/share/opencpn
/usr/lib/opencpn
/usr/local/bin/opencpn
/usr/local/share/opencpn
/usr/local/share/doc/opencpn
/usr/local/lib/opencpn

pi@raspberrypi:~/builds/oesenc_pi/build $ find /usr/ -name  "libsglarmh*"
/usr/lib/opencpn/libsglarmhf32-2.30.0.0.so

pi@raspberrypi:~/builds/oesenc_pi/build $ find /usr/ -name  "oeserverd"
/usr/bin/oeserverd

pi@raspberrypi:~/builds/oesenc_pi/build $ find /usr/ -name  "lib*_pi.so"
/usr/lib/opencpn/liboesenc_pi.so
/usr/local/lib/opencpn/libchartdldr_pi.so
/usr/local/lib/opencpn/libgrib_pi.so
/usr/local/lib/opencpn/libdashboard_pi.so
/usr/local/lib/opencpn/libwmm_pi.so

O found oeSENC but didn't load:

09:49:51 CEST: PlugInManager: Loading PlugIn: /usr/lib/opencpn/liboesenc_pi.so
09:49:51 CEST: Error: /usr/lib/opencpn/liboesenc_pi.so: undefined symbol: _ZTI10wxCurlHTTP

I get this one too (on x86_64 linux), seems to be related to the latest, post-5.0.0 changes pushed into the OpenCPN git repo.
