Right.. but that is the embedded version of windows. It will not run regular win32 apps. So no OpenCPN in Windows on a Pi2

[seandepagnier]

Why can't you recompile for embedded windows? If visual studio doesn't work mingw should.

ok so linux neophyte here that I am.

I am trying to install 4.0 on both myt raspberryt pi and my odroid.

How do I
a: upgrade the 3.2 install on the raspberry pi, or the 3.3 install on the odroid
or
b: uninstall the old version and install the new version....

Thanks in advance for the help.

Guy...
Simply install the new version, it replaces what is needed. Unless you built the old one manually and installed to /usr/local and want to install 4.0 from PPA the package to /usr
If it is the case, prior to the installation do

sudo rm -rf /usr/local/*/opencpn

ok that is currently compiling on the raspberry pi. Which I don't have a lot of hope for because it is so slow.

So I am trying to get 4.0 on the odroid, which I had high hopes for. (The lack of hardware opengl is really annoying on all of these boards. And I ordered a new raspberry pi2 to try before figuring out that it is still hampered by the closed proprietary chip that they picked... Sigh... I think that is going to be a waste of $65).

The odroid I installed from a custom package made by one of the members of the odroid community (maveric) who I think is on here too. Which supposedly gave me a good GLSHIM to make the whole thing work with some hardware opengl.

here is what is happening. (i don;t have a great grasp of linux yet. But I do know that I am trying to compile the source code, using a make file and that I have an error creating the make file because of library dependencies that are not being met. Namely wxwidgets (X windows code sections???).

so here is what happens:OK so I am trying to install the latest version of OpenCPN, 4.0

If I try and install it manually using this:
git clone git://github.com/OpenCPN/OpenCPN.git

followed by this:
$ cd opencpn # unless already in this directory.
$ mkdir build
$ cd build
$ cmake ..
$ make

which I understand and telling building a make file to get ready to comile the source code.
(There is a lot of magic that happens then and if you have just the right incantation.... Viola as the say in franceland..... out pops a new version of OpenCPN).

However I get an error about not having wxwidgets

So I read up on the wxwidget install on the odroid site. Which all keeps me going in a circle.... It wont install with my installed gl libraries that support some hardware acceletation that were so nicely provided by afore mentioned mavric.

Any help greatly appreciated.

Thanks,
Guy

The gl libraries you installed... how?

wxwidgets is just a software layer so you can swap the libraries it callse like glshim->opengles or opengl without recompiling wxwidgets. Really all you need is to apt-get the wxwigets, and if apt-get gets confused, then do it when the software opengl is in place then swap the libraries after, that should work.

ODROID Forum • View topic - Odroid for sailboat navigation? Help a non-techie?

I started that thread, and my only purpose in getting the odroid was to be able to run opencpn on it with the radar overlay. Trying to make a simple one box low power inexpensive unit with enough processing power to be able to use vector and raster charts and be realistic in it's performance. This thread was where I got the Mesa drivers for the odroid, and followed the instructions for a glshim and gles (drivers?) on this thread.

If you can review the thread and figure out where it is that I went wrong and how to get opencpn 4.0 to install it would save me having to reburn the linux distro on the card which takes 4 hours for some reason, and starting all over with setting the machine up and trying to figure out the graphics stuff again. I would really appreciate it...

Thanks again for the help!

I don't know much (anything) about Odroid.
I am also new to Linux.
I managed to get OpenCPN running on a CubieTruck with the help of many on this forum; I also have my Navico 4G RADAR scanner connected and it seems to be working well (installed in my attic).
Here are some instructions that I collected and refined for building the software required for CubieTruck:
Building and installing on CubieTruck with Hardware Acceleration | Official OpenCPN Homepage

Hope that helps,
JM.

Thanks JM

Your directions were what convinced me to buy a odroid and give this whole thing a shot.

I had the 3.3 Opencpn working on it. Although I was trying to figure out how to install the Garmin Radar plugin, which seems to have more support than the Navico unit. (I do think the Navico 4g unit is a really great idea, especially for low power small boat operations. However last I heard the plugin didn't support the 4g unit, and the navico/simrad/b&G plugin was kind of abandoned.) Besides I already had a garmin HD unit sitting around from another project...

The choice of the Odroid over the cubi truck was that the cubi truck didn't seem to have as actrive forum for helping this linux neophyte try to get it working, and the Odroid had a lot better preformance than the cubi truck. When I had opencpn 3.3 on it was working way better than I thought it would. Especially with the mali drivers that the odroid forum users provided.

My lack of understanding on how Linux really works is killing me here. Having been heavily invested in the windows world, and being good at that isn't translating very well at all.....

Sorry, I can't really help with the Odroid. I just wanted to set the record straight about the Navico RADAR plugin:

The 4G 3G Br24 Navico/Simrad/Lawrence/B&G RADAR plugin is working very well in testing. Will know better when it gets installed on the boat this spring.

If you had OpenCPN 3.3 working, It seems you should be able to get 4.0 working.

Good Luck,
JM.

With a little help on the odroid forum this afternoon I got it working.

It crashes instantly on selecting a vector chart, and I know I have solved this problem before I just don't remember how...

Where is the information on the Navico radar plugin?

Do you have g4 or only a g3.

You can run vector charts with 4.0 right?

Thanks,
Guy

I have opencpn 4.0 running on the odroid it is doing great except for a couple of problems.

One of which I know I have encountered before I just can't remember where.

I have installed the charts of California from Noaa. Both the ENC's and Rasters.

'The rasters work fine, but the ENC's crash opencpn here is what my output is when running from a terminal window.

As a troubleshooting step, disable OpenGL in the settings tab of OpenCPN. I'm guessing it will work with vector charts without OpenGL.
