OpenCPN Runs on Embedded ARM

Can someone share a recipe/instructions for the less technically inclined that will enable OpenGL mode please.

I got mine working but I was using vnc... but just yesterday I finally got some lcd displays so I have one which I can plug into the raspberry pi. The instructions I put in my last post, scroll up.

I thought that is what I had done, I only just compiled it.

Can you post the commands I would need to compile the 'right' version please.

WOuld the new version simply install over the old one or would I need to remove the old one and start again. If so, would a sudo apt-get purge OpenCPN work?

Many thanks for replying, I do feel that the Rpi OpenCPN is 'close' to being
usable and the perfect Marine Computer. BY swapping the USB and SD Card for a RaspBMC install it is also the perfect entertainment platform for the boat as well.

Looking at those instructions it looks like you have installed Cubian not Raspian to start with. Is this right? Also there seems to be some special instructions related to the pi but I can't find them. Sorry a bit of a beginner when it comes to compiling software etc.

It doesn't matter what distribution. Cubian is debian on cubie boards, rasbian is on raspberry pi. I'm pretty sure I am using raspbian. Just follow the instructions and make sure to read the README for glshim because it is slightly different, and post any problems or questions we can probably answer here.

See above for issues that I have had following the instructions.

One other question I am following the instructions as the normal pi user the last command make install seems to need sudo make install to make it work. Is this correct?

Maybe you could just comment out the line with CLOCK_REALTIME I've never seen that error before.

OK, commenting out the 2 lines around the if statement as below:

VCOS_STATUS_T vcos_semaphore_wait_timeout(VCOS_SEMAPHORE_T *sem, VCOS_UNSIGNED timeout) {
struct timespec ts;
int ret;
/** if (clock_gettime(CLOCK_REALTIME, &ts) == -1)
return VCOS_EINVAL;
*/
ts.tv_sec += timeout/1000;
ts.tv_nsec += (timeout%1000)*1000*1000;
if (ts.tv_nsec > 1000000000) {
ts.tv_sec++;
ts.tv_nsec -= 1000000000;
}

while (1) {
ret = sem_timedwait( sem, &ts );
if (ret == 0) {
return VCOS_SUCCESS;
} else {
if (errno == EINTR) {
continue;
} else if (errno == ETIMEDOUT) {
return VCOS_EAGAIN;
} else {
vcos_assert(0);
return VCOS_EINVAL;
}
}
}
}


sudo make GL resulted in a lot of warnings but no errors and completed.

Linking C shared library ../lib/libGL.so.1
[100%] Built target GL

I then followed the rest of the instructions and all seemed to build fine. I am using sudo make install rather than make install...does this matter?

However when I run OpenCPN I just get a grey window area where the chart should be when I switch to opengl mode. The texture compression cache option is greyed out and the use accelerated panning is greyed out. I rebuilt the chart database and restarted but still have the grey window area where the charts should be.

I do see a menu bar and can access the settings menu. But no OpenGL accelerated graphics.

Happy to do any other testing as I am really focused on getting this working.

EDIT: Just recompiling now from scratch from the top to check I didn't make any bloopers. I will post results in about an hour or so.

Hello boat_alexandra, and others readers,
Thank you for your work and supporting all the newbies
I'm using Cubietruck hardware. I restart the whole process this morning from a fresh install to sum-up what I've done. So here is the full and accurate recipe to have OpenCPN with hardware acceleration enabled on a CubieTruck :

- download the cubian desktop image Cubian-desktop-r1-a20-ct.img
- write it to an SD card with my Win32 computer, and boot the Cubietruck on it.
- I updated the system with the following :
$sudo apt-get update
$sudo apt-get install cubian-update
$sudo cubian-update –v
$sudo reboot

- then, I follow the instructions described in the OpenCPN page :
sudo apt-get install mesa-utils build-essential git cmake libx11-dev
At this stage, I tried glxgears : 45 fps. So, no hardware acceleration for OpenGL. I tried sunxi_disp_test, I saw the triangle figure, and the renderer is "Mali-400 MP". So, in this case, there is hardware acceleration.
I understand, that I need now the glShim to make OpenGL working with OpenGL ES. So, I continue with the OpenCPN instructions :

- download your version of glShim :
$ git clone https://github.com/seandepagnier/glshim.git
$ cd glshim
$ cmake .
$ make GL
Build is successful.

But now, I don't understand the 2 following instructions :
$ sudo cp glshim/lib/libGL.so.1 /usr/local/lib/
$ sudo cp -r glshim/include/GLES/ /usr/local/include/

On my filesystem (fresh install), there is no libGL.so.1 in /usr/local/lib/. So I typed the following to know where is located the library used by glxgears :
$ ldd /usr/bin/glxgears
libGLEW.so.1.7 => /usr/lib/arm-linux-gnueabihf/libGLEW.so.1.7 (0xb6f60000)
libGLU.so.1 => /usr/lib/arm-linux-gnueabihf/libGLU.so.1 (0xb6f17000)
libGL.so.1 => /usr/lib/arm-linux-gnueabihf/libGL.so.1 (0xb6ecc000)
So, instead of :
$ sudo cp glshim/lib/libGL.so.1 /usr/local/lib/
I think it should be :
$ sudo cp glshim/lib/libGL.so.1 /usr/lib/arm-linux-gnueabihf/
and then :
$ sudo cp -r glshim/include/GLES/ /usr/local/include/
I think this last instruction about includes is for further compilations (this destination directory is empty on my fresh install).

I then tried to run glxgears, to check if OpenGL can now run with HW acceleration. The result :
cubie@Cubian:~$ glxgears
libGL: built on Aug 2 2014 14:32:50
302 frames in 5.0 seconds = 60.325 FPS
297 frames in 5.0 seconds = 59.226 FPS
297 frames in 5.0 seconds = 59.224 FPS
^C
cubie@Cubian:~$
So, 60 is a bit better than 45, but far from 100 and more... I asked glxinfo to check :
OpenGL vendor string: ARM
OpenGL renderer string: Mali-400 MP
OpenGL version string: 1.4 glshim wrapper
Nice, it seems to work. Let's continue with the OpenCPN instructions :

$ sudo apt-get install libgtk2.0-dev gettext git-core cmake gpsd gpsd-clients libgps-dev build-essential wx-common libwxgtk2.8-dev libglu1-mesa-dev libgtk2.0-dev wx2.8-headers libbz2-dev libtinyxml-dev libportaudio2 portaudio19-dev

At this stage, glxgears still 60 fps, and glxinfo still on Mali-400 MP. So, it looks good. Let's continue :
$ git clone https://github.com/ssvb/glues.git
$ cd glues
$ cmake .
$ make
Then, the same issue with this cp instruction :
$ sudo cp libGLU.so.1 /usr/local/lib
There is no libGLU.so.1 file in /usr/local/lib. According to my previous ldd /usr/bin/glxgears, it should be :
$ sudo cp libGLU.so.1 /usr/lib/arm-linux-gnueabihf/
That's what I've done.

Then, I tried glxgears again : 60 fps, and glxinfo is still ok with MALI400. Great, let's continue, with the OpenCPN compile and install :
$ git clone git://github.com/OpenCPN/OpenCPN.git
$ cd OpenCPN/
$ mkdir build
$ cd build
$ cmake ../
The correct libs are found during the CMake process :
-- Found OpenGL: /usr/lib/arm-linux-gnueabihf/libGL.so
-- 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
-- Include: /usr/include
-- Found OpenGLESv1

it smell good... Go on :
$ make
$ sudo make install
$ opencpn

Enabled opengl in the settings. Siwtch off opencpn, and edit the file located in your home directory : .opencpn/opencpn.conf to add
DebugOpenGL=1
just the line after
[Settings]
save the file and quit. Then restart opencpn, and check the log file opencpn.log, you should find this :
16:00:30 UTC: OpenGL-> Renderer String: Mali-400 MP
16:00:30 UTC: OpenGL-> Texture rectangle format: de1
16:00:30 UTC: OpenGL-> Vertexbuffer Objects unavailable
16:00:30 UTC: OpenGL-> Framebuffer Objects unavailable
16:00:30 UTC: OpenGL-> Using Stencil buffer clipping
16:00:30 UTC: OpenGL-> Using Scissor Clipping
16:00:30 UTC: OpenGL-> Using oes etc1 compression
16:00:30 UTC: OpenGL-> Compressed tile size: 128kb (6:1)

So it looks that it works. I need now to try with charts, but what I see for now is not as fluent as a desktop computer. Of course, current consumption and price have to be taken into acocunt to make a full comparison !
I'm also waiting for my SSD drive to put everything on it and check if it increases the performances.

...and thank you to boat_alexandra for your good job.

It sounds like opencpn is not using the right library. I don't know why but many people fail at this, so don't feel bad.

Did you make symlinks for glshim or set LD_LIBRARY_PATH correctly? Can you run glxgears with acceleration. It should get very fast of more than 300 per second. You should be able to run glxinfo as well and even bloboats. If these do not work, you cannot expect opencpn. What says opencpn.log?

Still compiling! I used the instructions you pointed at, except for using sudo make install at the end of the opencpn section.

There are no instructions for making symlinks or setting paths in the information!

You might be able to speed up builds by cross compiling or using distcc... I did this, but don't forget to add -march=armv6 to cflags

I think i'll wait for the pi to compile....enough things to try and work out, and looking at various cross compiling articles it might be a step too far for me

OK this is what happens, here is the output from the cmake, it seems to find opengl and opengl es!

No difference in opencpn when I run it and select OpenGL.

When I run glxgears I get:

error: Couldn't get an RGB, Double Buffered visual

So it looks like there is no OpenGL working in Rasbian.

I have followed the instructions to the letter twice now and rebooted in between. What am I missing? Everything compiled glshim and glues OK after the hack you suggested.

No idea what to do next!

I should post on the instructions, if you can't get glxgears working, forget out opencpn.

Ok. Try this:

LD_LIBRARY_PATH=/usr/local/lib glxgears

Assuming you copied libGL.so.1 there

If that doesn't work, try:

cd /usr/local/lib
mv libGL.so.1 libGL.so

and try glxgears again

Ok did that. The first command works.

glxgears opens a window but no gears appear and I get:

Just keeps scrolling.
