OpenCPN is the base level software. It provides all the basics for planning and navigating. There are a range of Plug Ins that extend this functionality to, hopefully, increase its usability and utility. OCPN_DRAW_PI is one such Plug In. It allows the user to draw objects, other than Routes and Waypoints on the chart. It also allows, in conjunction with the Watchdog Plug In, to use some of these objects to set alarms, i.e. AIS targets coming close but not on a collision course, No Go areas (Exclusion Boundaries) and irregular shaped Anchor Watches (Inclusion Boundaries).

So, install OpenCPN first and make sure it works, then, if you feel like it install the OCPN_DRAW_PI Plug In. Currently both of these that I have provided are beta versions which are in the final test phase. They should work OK, but they are subject to changes as we try to finalise for a 'production' release, i.e. OpenCPN 4.2 and OCPN Draw 1.0.

I have not provided the Watchdog Plug In as it currently does not work on the PI, although it does work well on all the other supported platforms. The PI is rather new and 'experimental' (that's what it is for after all) and has not yet had the effort put into it to stabilise all the Plug Ins.

PS. On the PI to install a *.deb file you will need to issue 'dpkg -i /path/to/file' as super user. The final versions of the code will be in the PPA's which are installable through the normal methods, i.e. apt-get or update manager.

It should work, what is the problem?

Jon,

Did you try my rpi_fixes branch? It cannot be merged because the near 4.2 release, but it should unlock the hardware accelerated opengl for raspberry pi giving me mostly 15-20 frames per second on 1280x800 resolution. I would like some feedback... If it finds the mesa drivers it might not be faster, so possibly must add the location of the right libGLESv1_CM.so to LD_LIBRARY_PATH... Depending on distribution this can be in different places and may or may not be in the right place so I want to work this out.

But building OpenCPN with wx2.8 failed:

I think you haven't compiled wx with opengl
In your wx 2.8 directory
rerun configure as before but with the parameter --with-opengl;
configure --with-opengl
make
make install

It seems you also need the latest OCPN from git for arm, update it
and recompile OCPN.

Please, which branch is that. "armlinuxfixes" or?
Would be fun to test.
Thanks

From his private branch I think:

https://github.com/seandepagnier/OpenCPN/tree/rpi_fixes

Cheers,

I noted:

47 years ago,,,, :-)

Shows 8 days ago for me.

seandepagnier · 07-01-2016, 08:39

Maybe because the raspberry pi clock somehow is using the year 1970 by default.

Hakan · 07-01-2016, 09:44

all..
Thanks for the link. (Was not use to the need to scroll down in a branch list

) Sean you're a productive fellow.
It's building now,will use one hour or so. This was initially found:

Code:

-- Found OpenGL...
--     Lib: /usr/lib/arm-linux-gnueabihf/libGLU.so/usr/lib/arm-linux-gnueabihf/libGL.so/usr/lib/arm-linux-gnueabihf/libSM.so/usr/lib/arm-linux-gnueabihf/libICE.so/usr/lib/arm-linux-gnueabihf/libX11.so/usr/lib/arm-linux-gnueabihf/libXext.so

Comments on that??

OK - I've built and it runs as usual. Log file says:

I searched and found this:

/opt/vc/lib/libGLESv1_CM.so
How do I know this is the right one and how and where do I point to that??

Code:

export LD_LIBRARY_PATH=/opt/vc/lib/
./opencpn

You should get different stuff in the log file as well, if not, maybe post the output of cmake from a clean build directory.

I think on some distributions the standard path is /opt/vc/lib so maybe I should also search there to avoid the LD_LIBRARY_PATH issue

I'm not sure, you have OpenGL dev files but not the libraries or it can't find them.
what's the output of:

Code:

dpkg --get-selections | grep -i mesa

ie list all installed packages with name containing mesa

Hope you have nothing important on this box, seems all this stuff may not end well, kind of mess only a full install will recover, just saying.

No problem, easy to back up when everything is on a 16GSD Card.

Sorry I am struggling with this,
Thanks for your help.
