Please do! It's fun and instructive. And then you can update your program to latest version when the developer comes up with new features. Not less if they happens to build in RPi OpenGl support.
But to build the stable 4.0 version out of the downloaded source calls for some Git commands like:

Git checkout fb31e8e88d7b4686345786d47d9eb7a5f8875685

The extensive number is the identification for the commit that created the stable version 4.0
If you would like to test that version built on my RPi-2 it's here: https://dl.dropboxusercontent.com/u/....0-1_armhf.deb

Good luck building OCPN! As you've noticed here are a lot of knowledge to chair.

Can you run es2gears on the rpi2? Does it work in a window? On the raspberry pi, it took the fullscreen which is a problem for opencpn as the toolbar becomes invisible.

Can you run two copies of es2gears at the same time and move the windows around? What says the es2_info output?

[seandepagnier]

Maybe you can use open source drivers?

Never heard of "es2gears" but I understand it's some test tool so I can have look.

For OCPN I've no problem with windows nor the toolbar. I can use OCPN as normal, although without OpenGL, together with other programs like the Chromium browser I'm writing in just now. Though OCPN complains about some some missing color drivers which I could spend some time to investigate. But so far I've used no extra drivers nor nothing else except the framebuffer adjustments described earlier.

The talk you refereed to about a new OpenGl driver seems promising for the future.

Thanks Håkan

Thanks Hakan for the compiled 4.0.0-1 version; that's the one I will promote considering it is the last stable version.

You aren't using opengl or getting hardware acceleration. With opengl the frame rate is 2-4 times higher and so much smoother operation.

I found another thread that hacks around it
Raspberry Pi • View topic - Hardware 3D in a window demo

This is certainly possible for us to do to get it working with opengl right now

For info:
In my view the RBpi-2 is now rather stable. I have:
> Updated Debian from Wheezy to Jessie see: http://www.cruisersforum.com/forums/...ml#post1837785 Everything else is "out of the box".
> Installed the build dependencies for wx-3-0 as of: Compiling - Linux | Official OpenCPN Homepage
> Build OCPN 4.1.530 including WMM_pi and BR24Radar_pi
I got the following OpenGl log:

I can confirm.

I have been running O on the RPi2 for the past 3 weekends in a row. Without hardware acceleration, and using Raster charts, USB AIS (dAISy), and USB GPS, it is very stable and quite responsive.

I cannot get hardware acceleration to work, and I have been having trouble getting ENC charts to work. But haven't spent many hours attempting to do so.
