OpenCPN Runs on Embedded ARM

[bobmor99]

Hi ticki,
I am having trouble building OpenCPN on my (brand new) BeagleBoard xM.
I've searched and scratched my head a lot before posting. :-)
Any help is much appreciated.

root@beagleboard:~/opencpn/build# cmake ../
-- *** Build Architecture is armel
-- *** Staging to build opencpn 2.6.1718 ***
-- OpenGL not found...
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:70 (MESSAGE):
Could NOT find wxWidgets (missing: wxWidgets_FOUND)
Call Stack (most recent call first):
/usr/share/cmake-2.8/Modules/FindwxWidgets.cmake:818 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
CMakeLists.txt:130 (FIND_PACKAGE)

P.S. I am running the Angstrom Narcissus-generated Beagleboard validated Gnome image.
I have installed quite a few additional packages (via opkg) e.g. gcc, to get to where I'm stuck.
Apologies to all if this is not a valid Cruisers Forum topic.

You need wxWidgets. It will probably need to be compiled from scratch from wxwidgets.org sources.

You have to Install the wxwidgets, you dont Need to Compile you can Download it ? See te thrad here : Index of /ticki

Also Install liebeglu via opkg install libglu .
See the threads bevore with Alu.

Best regards

Hi Ticki,
Thank you very much for your help. OpenCPN now runs very nicely on my Beagleboard -xM.
One very minor point (for other noobs like myself), to install libglu, you need a "1" at the end:

 opkg install libglu1

I also installed mesa - not sure if that was necessary.

opkg install mesa

Thanks Dave.
I managed to get wxwidgets compiled. I ran into some other confusion and shifted my focus to ticki's already rolled stuff. I'll try again to compile OpenCPN from scratch for the Beagleboard. If successful, I'll document the steps for other noobs like myself.
Cheers

Hi bobmor99,

nice to hear that there are more beagleboard user.
Do you work with cm93 charts? If OCPN scans my cm93 folder than it hangs.

Hi Alu,

nice to hear that there are more beagleboard user.
Do you work with cm93 charts? If OCPN scans my cm93 folder than it hangs.

CM93 (also know as vector or ENC) charts cause OCPN to hang. The raster charts work great.
I am not experienced enough to help nohal and ticki with the debugging. I need to learn to compile OCPN from scratch so I can add some debug stuff for the CM93 hangs.
Cheers

I am hoping to better understand how to compile/(c)make OCPN on the Beagleboard.
(Back in the day, I compiled (and linked) stuff for a living but this collaborative internet development is equally amazing and confusing.)
At any rate, I have a couple of new sticking points.
1) cmake is down to a couple of complaints:
a)

-- Could NOT find TinyXML  (missing:  TINYXML_INCLUDE_DIR TINYXML_LIBRARIES)

along with

-- tinyxml library not found

b)

-- Gps library not found

2) make gets to 7% and then complains

Regarding tinyxml, I downloaded and unzipped it. Then (per readme) did a make clean, followed by a make. I can't find any sort of tinyxml.lib.

Regarding libgps, I could only find libgps19 or lesser via opkg. I know there are concerns about v19 vs. v20 but my brain is full at the moment.

Many thanks in advance.

hi bobmoor,
my way was the following:
i createt virtual machine with xubuntu.
the i installed the Narcissus SDK for the Beagleboard XM.
i installed the cmake and cmake gui
then cross-compiled all required librarys which are not available in Angstrom (wxwidgets 2.8 , tinyxml) and added it to the sdk.
then compiled opencpn with cmake.
then installed all librarys and opencpn wich i compiled by self manuall
if you like to compile it on Beagleboard directly you must compile all by self and install, or if available you must install the "dev" versions, so that all header-files also available.
the complete way to do all here, is i think not the way , the most interestet user only like to install.
I am at the moment underway , so in two weeks i back home and i upload all.

regards
ticki

Can someone report the performance difference for opengl on angstrom? Are you using the hdmi or parallel to and lcd? It's also possible to output to a vnc session or something with terrible performance.

[bobmor99]

I am just using an HDMI monitor and am very happy with the performance.

Ahoy there Trition Yawl - did you manage to get OpenCPN working on your Trim Slice? I have just got one for the express purpose of using OpenCPN only to find that the standard (natty/precise) versions of OpenCPN is not compatible with the ARM based Trim Slice. I have no programming skills so doubt whether I will be able to compile from source code. Any suggestions or hints from anyone gratefully received.

Thanks Tom

[tomfb630]

Anyone able to update this link?- It does not work.

Whoops that is the link pasted by Nohal re Tikk's ARM stuff

Thanks

Because the arm architecture is similar between your android tablets, 'pi' and Beagleboards - and because you are using Debian, Ubuntu and other Linux flavors that utilize apt, aptitude and dpkg , I have a few useful hints.

Package names vary depending upon your flavor of choice. So, when following installation instructions for OpenCPN or any other program you may encounter 'file not found' issues when trying to satisfy dependencies.

The * (asterisk) can be very useful in these situations. For example, if you are getting 'file not found results when trying to install wxgtk with apt, try this: 'apt-get install wx* Fedora's yum package manager is much more robust when using the wild card * as in the wx example above, but you will get a long list of packages beginning with 'wx'. Your task will be to scan through them until you locate the appropriate package name and version you want to install.

I prefer Fedora in part because of the yum package manager. If I receive a message when launching a program from a shell that a shared library such as something.so.6 cannot be found, in yum I can simply download the library package containing 'something.so.6' thusly: 'yum install something.so.6' This will download the package containing 'something.so.6' and any dependencies.

Unfortunately the stable arm version of Fedora 17 is for the armV5tel architecture, but still compatible with armV7 cpus. I have used the android apk called Linux Deploy to install this Fedora arm version to my Motorola Xoom. OpenCpn installed into Fedora without any problem. I am still however trying to get zyGrib installed with buttons.. It installs, but lacks icon buttons.
