Having used my Raspberry Pi3 for a short time with OpenCPN 4.5.127,
and the latest large UK testversion of oeSenc.

With Wayland, the latest updates plus kernel 4.9.5-V7+. (now 4.9.6)

VC3 experimental driver switched on. And the 99-fbturbo file removed.

All seems to work very well with fast screen movement.

Dirk, thanks for the update details,

Regards,

Bram

Re: OpenCPN on Raspberry PI2

could you please make a guide to the steps taken starting with a specific raspbian image? I think it would be useful for the wiki

Hi B-A,

are you writing this to me ? English is not my native language.

And the kernel version to 4.9.6 etc. are not yet the official versions.

But it works great here in combination with the OpenCPN beta and the Oesenc chart system.

Progress all around.

Regards,


Bram

So the Thames Estuary looks like with the Oesenc charts.

OK, I started from scratch, with a fresh, full Debian Jessie. Here is my log:

From a fresh 2017/01 Debian Jessie to OpenCPN


Enable the SSH server
I like to access the PI3 via ssh for easier copy/paste
On the Raspberry run:
$ sudo touch /boot/ssh
After reboot you can connect to the PI via ethernet cable (or configure wireless)

Update Debian Jessie and Linux kernel
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo apt-get autoremove --purge
$ sudo apt-get install rpi-update
$ sudo BRANCH=next rpi-update
$ sudo reboot

Use RASPI-CONFIG to enable OpenGL, etc

Use
$ sudo raspi-config
=> Advanced Options, “GL Driver”, enable
This also installs a couple packages the first time used (compton libconfig9).
=> localisation Options
Select timezone, keyboard, etc

Remove obsolete config files
$ sudo dpkg --purge $(COLUMNS=200 dpkg -l | grep "^rc" | tr -s ' ' | cut -d ' ' -f 2)

Tools I like to use
$ sudo apt-get install htop joe

Prerequisite packages for OpenCPN

Per OpenCPN doc, these are the required packages:
$ sudo apt-get install build-essential cmake gettext git-core libgps-dev wx-common libwxgtk3.0-dev libglu1-mesa-dev libgtk2.0-dev wx3.0-headers libbz2-dev libtinyxml-dev libportaudio2 portaudio19-dev libcurl4-openssl-dev libexpat1-dev libcairo2-dev

I have no use for GPSD, so I omitted “gpsd gpsd-clients” above.

Also needed for OpenCPN (detected when opencpn cmake couldn’t find these)
$ sudo apt-get install liblzma-dev libelf-dev


Get source code for OpenCPN and compile

$ mkdir ~/CODING/
$ cd ~/CODING
$ git clone https://github.com/OpenCPN/OpenCPN
$ cd OpenCPN
$ mkdir build
$ cd build
$ cmake ../
$ sudo make install

Remarks:
  • I couldn't get "Jessie light" plus X, lightdm, ldxe ... to work so I went with the full Raspian Jessie distribution.
  • Above made opencpn work with opengl and vblank_mode=0 glxgears
    shows ~650 fps. I can get it to ~750fps by uninstalling compton.


Cheers


Dirk

Re: OpenCPN on Raspberry PI2

To whom it may concern.
Trying to build OpenCPN from scratch as of yesterday, I am running into a few issues:

Linux pidev 4.4.38-v7+ #938 SMP Thu Dec 15 15:22:21 GMT 2016 armv7l GNU/Linux
trying to get the source, I get the following error:
apt-cache search opencpn
opencpn - OpenSource Chart Plotter/Navigator
root@pidev:/home/pi# add-apt-repository ppapencpn/opencpn
You are about to add the following PPA to your system:
A Chartplotter and GPS Navigation Software.

OpenCPN is a free software (GPLv2) project to create a concise chartplotter and navigation software for use as an underway or planning tool. OpenCPN is developed by a team of active sailors using real world conditions for program testing and refinement.

aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Raspbian/jessie

trying to clone from github works fine, but gives me Version 4.2.0
building it, following Allisdair's tutorial, gives me the following issues:
building with:
-DBUNDLE_DOCS=ON -DBUNDLE_TCDATA=ON -DBUNDLE_GSHHS=HIGH
The make file terminated after approx 2h! w/out any noticable error.

But then the sudo make install command failed as following:
Install the project...
/usr/bin/cmake -P cmake_install.cmake
-- Install configuration: "Release"
-- Installing: /usr/local/bin/opencpn
-- Installing: /usr/local/share/opencpn/gshhs/poly-c-1.dat
-- Installing: /usr/local/share/opencpn/gshhs/wdb_borders_c.b
-- Installing: /usr/local/share/opencpn/gshhs/wdb_rivers_c.b
CMake Error at cmake_install.cmake:52 (file):
file INSTALL cannot find
"/home/pi/usb_hdd/OpenCPN/data/gshhs/poly-l-1.dat".

subsequently, trying to run it, gave the following error:

opencpn

(opencpn:8223): Gtk-ERROR **: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
Trace/Breakpoint ausgelöst


I gave it another shot w/ GSHHS=CRUDE.

make it (again)
the sudo make install command then worked OK,

but the run time error about GTK2 and GTK3 mixture remained.
Allisdair's pre-compiled version 4.2.0 works like a charm.

This is my 1st post here, and I couild not find anything similar, searching this thread.
Best Regards

Welcome aboard.

re:

Which github repo did you use?

Thanks

Hi there,
Well I followed Alistair's tutorial and I used
git clone git://github.com/OpenCPN/OpenCPN.git

Re: OpenCPN on Raspberry PI2

Sorry, I have to correct myself. Since I got no running version from my own compilation, as described above, the Version 4.2.0 is of course from Alisdair's precompiled package, which I installed. Hence, the statement, that github gave me Version 4.2. is wrong.- Sorry for the confusion.

Re: OpenCPN on Raspberry PI2

OK, no problem.

But, are you able to compile from the "official" OpenCPN github site?

$ git clone git://github.com/OpenCPN/OpenCPN.git

Hi Dave, I'm lost
I wrote
Well I followed Alistair's tutorial and I used
git clone git://github.com/OpenCPN/OpenCPN.git

so where is the difference ?

git clone git://github.com/OpenCPN/OpenCPN.git
git clone git://github.com/OpenCPN/OpenCPN.git

I did a git pull 2b sure that I have the latest version. It says "up to date"
I CAN compile/link, but I am still getting the run time error about the mixture of GTK2 and GTK3

Why not just load openplotter?

Everything is done for you then, kplex on there, signalk, Opencpn plus all the plugins & much more.

OpenPlotter RPI | Sailoog

Yep,
I definitely have OpenPlotter on the radar, but ..

"Everything is done for you then"

...that's the issue. I don't like ready made things (blackboxes), because they make me fully dependant on what others have made, or might abandon at some moment in time... I have built 95% of what OpenPlotter does by myself and I want now to finish up by getting an own compiled version of OpenCPN. Then I'm done for it, and I can decide whenever I want to change something in my setup, or not. IT's about being connected to the root of the things and mastering it yourself... if you know, what I mean...
Anyway, thank's for the recommendation.
Best Regards
