OpenCPN Runs on Embedded ARM

I have the same issue as Eirik on the Raspberry Pi 2 board.

I have the same CMake output as he has, and below is the full output of make:

I can't find a package that contains libdri2. nor can I find it in CMake or Makefile searches, so I can't just remove it and move on.

Ideas?

I'm afraid you guys are simply skipping a few too many chapters in the book. We will get to it, but give us a bit time...

I recently installed the latest openCPN by compiling from source on raspian on the quad-core raspberry pi board. I simply followed the instruction on the site for Debian (dependancies & commands), do I now have OpenGL working or not?

How can I test whether openGL(es) works? Is there an OpenCPN command to give me that information?

Yes, try manually running the ld line removing libdri2. I believe it is needed by cairo which is used by gtk which is used by wxwidgets, but these functions in cairo that use libdri2 we don't actually use, but it's needed to resolve all the externals unfortunately. If you were to say, build using wx-qt, or statically link with libcairo, you could probably avoid this issue. For now I just install libdri too, it's in a dev package for mesa I think.. not sure can't you just search the packages which whichever one provides this file (obviously it isn't libdri2-dev, but something like libegl1-mesa-dev or libgl1-mesa-dev)

check your log file. afaik (I don't have a rpi2) the gpu is identical to the original raspberry pi which means it isn't very good compared to boards like banana pi or cubie truck (which have mali graphics) and doesn't support opengl in a window, so the toolbar and other windows (like setup status, chart bar) are invisible (although you can still click on them) which makes opencpn basically unusable.

Can someone please try the new completely open source drivers for the raspberry pi? You need to patch the kernel, but it would be worth it as you would have a completely free opengles stack, and it might work a lot better.

Very strange. I did a grep for it, but it came back with no results. I must have typed the command wrong. Thanks for that link!

What's odd to me is that I already built OpenCPN a few times on this installation, just without OpenGL. Now that I'm going down the path of trying to improve performance the build is failing. I thought maybe it was a recent push since it was the same error as another person was reporting, but that was simply a guess.

I will look at that today and over the weekend.

I hope these reports don't come across as complaints. Overall I am thrilled with the OpenCPN product and developer support. My intention is just to give feedback to you guys as I try different things. I'm also in the software industry, and I understand your pain, truly.

But also for someone like me who can only work on the product in spurts here and there, the active development can cause confusion and mistakes. Things are not the same as they were a month ago - not in OpenCPN, not in hardware, and not in OS images, so the fixes I discovered back in January don't apply today.

I'm not frustrated at all, but I can see that a 750 post thread on the struggles with this product could lead you to believe that. To give you some feedback of an unequivocal success, I built OpenCPN on the RPi2 last week in two days (with no OpenGL), and ran it all weekend. I even gave a talk about how to do it to the other boaters we met up with. I try not to plug my blog here unless it's relevent, but there's a full write up on it.

We are pushing the limits of this product on small, cheap, underpowered hardware. OpenCPN runs flawlessly on my laptop, but nobody complains about success. It also runs (sometimes well, sometimes not so well, but it runs) on these ARM boards, and that is a feat in itself.

[dstrout]

Has anybody tried OpenCPN on the cubieboard4 (CC-A80)? I tried it on my pi2 and its not quite the performance I am looking for. From the discussions here, the cubieboard3 looks like a winner, but faster is always better, so I thought I would ask about the cubieboard4 before I place an order.

thanks,
Dave.

Just as a further follow-up to earlier posts and trials:

So you have installed glshim before running glxinfo? Keep in mind recent opencpn already has glshim builtin.

No, glxinfo and glxgears are included in the Ubuntu package for the Utilite.

I tried looking for libdri2, and found something at github; robclark/libdri2. Seemed correct went on to compile/install, and it seemed OK, but made no difference when compiling O. i.e. it would stop at the same place. I don't know whether it is the correct version or if it has installed correctly (is there a way to find out)? Anyone found another source for it?

I then removed the dri2 reference in CMakeLists.txt. Now compilation went fine, and O installed and runs OK. OpenGL does of course not work.

Hello everybody! At the moment I have some trouble with vector charts. I'm all new to Raspberries and Linux and whatnot, so I really can't follow your discussions that well. Maybe if I could I wouldn't need to answer. I just bought a Rpi B+ (by mistake, wanted the Rpi2) and have been tinkering around with OpenCPN.

Yesterday I got it working after following these instructions: Pi Chart (using the opencpn_4.0.0-1_armhf_tides_map.deb version or whatever you call it). I downloaded some old raster charts and they loaded perfectly fine. Then I wanted to try some vector charts and got some of the free ones from https://openseachart.org/doku.php/enc . It looked like they loaded up like they should in OpenCPN, but they don't show on the map.

I have seen here that you refer alot to logs and stuff, so I went into the log (not really knowing what to look for) and found this:

Error: NO ClassRegistrar in InitENCMinimal
Cannot initialize ENC file /bla-bla-bla-position/C020008.000
...initialization failed for /bla-bla-bla-position/C020008.000
CreateChartTableEntry() failed for file: /bla-bla-bla-position/C020008.000

Any advice? I registred and posted here since you seem to know a great deal about these things, and I think I will need some help before getting this thing to work with charts and GPS and so on. If I'm posting at the wrong place, or if I missed a quick-fix for this issue, I'm sorry.

[petter5]

All maps can be installed from the chart downloader plugin, no need to use openseachart. Install the plugin with apt-get install opencpn-plugin-chartdldr
( assuming that trhe plugins is avalable from your sources)

This is the series of comands I ran to build libdri2 from source. I could not find a package that had it included for the RPI2.

sudo apt-get install autoconf xutils-dev
git clone https://github.com/robclark/libdri2
cd libdri2
./autogen.sh
./configure --prefix=/usr
make
make install
ldconfig

I then deleted the opencpn directory and re-cloned it (unrelated, it was my fault, but may have an impact) -- and then it compiled just fine overnight.

I now have an updated version of O running on the RPI2, but there is some sort of permissions-based performance issue. If I run "sudo opencpn" it is exceptionally fast -- but I can't access my GPS or AIS data streams. If I run "opencpn" it's very slow... Still investigating this.

[seandepagnier]

exceptionally fast how?

exceptionally fast how?

10-20 FPS as superuser
vs 0-1 FPS as pi user

is this with or without opengl? Obviously something is seriously wrong. What about cpu usage?

What differences for glxgears and es2gears for user vs root?

is the user in the video group?

I have been looking at various single board computers and a few I found I think would be better than the new raspberry pi:

odroid-c1
pcDuino3-nano

both use mali graphics which is known to work well. We know there are issues with broadcom, but what about the others? I haven't had any feedback and don't have any boards with these for linux (apparently they work in android more or less though)

I just completed over 1000 miles using Raspberry Pi2 with Opencpn 4.0.0. GPS data was from a BU353. There was no AIS input. Frame rate was acceptable, and there were no crashes. It is not as fast on the Pi2 as on my window machine, but a lot less power is consumed. So if you are getting only getting 0-1 FPS - there is something amiss in your setup.
