I like the Qbee-X image because everything works including sound, 1080p video and preinstalled Mali stuff.

I wrote an instruction for installing the OpenGLES stuff on this image, and I get glxgears frame rate of 500-550 FPS.
After installing OpenCPN and updating the raster charts with the cache (It took about 6 Hrs) OpenCPN works quite well, very smooth panning and moving of charts.

I just finished making a shell script to install all of Sean's Plugins and they work well.

If you have any questions, just ask.

Thanks,
Freddie

VICTORY!!
I got OpenGL accelerated OpenCPN running on my cubietruck.
I started with this image: http://share.korepwx.com/cubian-desk...-a20-ct.img.7z
And then followed Building and installing on Cubieboard 2 with HW acceleration | Official OpenCPN Homepage

I do not know what you mean with Seans plugins? Is it glshim and glues?

In the weekend I can create an SD image with my work so anyone interested can use that.

Thanks

regards
Peter

No. the plugins for opencpn, like weather routing and climatology.

Peter,
Congrats! Great news!

Would you be willing to make a new try to get it running on the RaspberryPi?
Will the last work on the Cubie help?

I want to focus on the cubietruck now, but maybe I will give the raspberry a new try later.
Now I have to the get autologin, start opencpn automaticaly, get the bluetooth keyboard running and package everything in a waterproof case. You now the last 10% that takes 90% of the time

Peter,
have you done anything different from owlhead's instructions? As posted, I followed the instructions but failed with CB2

I followed the instructions and did nothing extra.
The instructions had some minor issues, like wrong path when running cd or cp.

Where did you get stucked?

I did eveything as described w/o errors but GLXgears states low fps (see posts #237 - #240), so I don't have a clue what's wrong...
Martin

[MAd]

I've now focused on glxgears, if I understand correctly, I need to make sure it's using the right libraries, so I renamed the original libGL.so.1 and libGLU.so.1 in /usr/lib. glxgears doesn't start anymore (missing libGL) so I tried "LD_LIBRARY_PATH=/usr/local/lib glxgears" (I've copied the newly compiled libGL.so.1. and libGLU.so.1 to /usr/local/lib before), glxgears now starts but fps is still <50. Any ideas?

Make sure it can find libGL.so not libGL.so.1, so either a symlink, or copy to the new filename.

[MAd]

Doesn't help - still 50fps
What I did:
1) renamed libGL.* and libGLU.* in /usr/lib/arm-linux-gnueabihf (found with $ locate libGL)
2) added two symlinks in that directory (libGL.so => /usr/local/lib/libGL.so.1 and libGLU.so => /usr/local/lib/libGLU.so.1), the so.1 libs are compiled from glshim and glues as described in instructions from owlhead
3) glxgears didn't start, error message was, that libGL.so.1 can not be found, so I've added two more symlinks in that directory (libGL.so.1 => /usr/local/lib/libGL.so.1 and libGLU.so.1 => /usr/local/lib/libGLU.so.1)

Now glxgears works, but still 50fps
What is the magic, that for some the instructions above from owlhead work, but not for me
Martin

[MAd]

Well, glxgears still states <50fps, but OpenCPN works fine I've just added two maps and built the texture cache, it's now pretty fast! So I will now add all my maps for the southern baltic sea, hope this also works as expected.

It's possible on some setups that glxgears is limited to vertical refresh rates make it not always the best program to test with. In any case, if you notice a significant improvement over non-opengl mode then it's working.. it should be smooth for zooming panning and rotation etc... One way to tell is to look at the opencpn.log file and see which compression format it is using s3tc dxt1 is used on desktop gl, and would be possible only with software rendering where as etc1 should be used on gles systems.

I'm sorry. I was a little bit optimistic when it comes to my success.

When using vectorcharts I can enable "extend light sector" and get it working. I thought that it was only possible when opengl was enabled and using hw acceleration.

When runing cmake I get:

-- Found X11: /usr/lib/arm-linux-gnueabihf/libX11.so
-- Found OpenGL: /usr/lib/arm-linux-gnueabihf/libGL.so  
-- Found OpenGL...

--     Include: /usr/include

It seems like it is not using the newly compiled libGL.so.1 and libGLU.so.1

If I run

cmake ../
make 
sudo make install

Start opencpn

export LD_LIBRARY_PATH=/usr/local/lib/
opencpn

Push enable opengl, it crashes.

ldd /usr/local/bin/opencpn

And some more information.
After enabling opengl, opencpn crashes. Below is the output on the console:

As far as I understand opencpn uses the correct libraries:

Are you sure you are using my fork of glshim? I got this error with the mainstream. Otherwise, you will have to debug glshim and find why it cannot initialize the EGL display.

Does glxgears work?
