Re: Chart Problems on Raspberry Pi

Thank you both.

I'll try both tomorrow and let you know.

Cheers

Re: Chart Problems on Raspberry Pi

Alisdair.

Just tried yours. Install needs libportaudio.

New image and updated O'clock 900 ( medium) 512 ram 32 for GPU.

Colours ok now and perhaps zooms a little faster but still crashes if try zoom in on Solent. My patch of the Med is fine though!

Definitely progress.

I'll prepare another card and compile the ver from git hub now.

Thanks

Unnnecessary edit: This was CM93

try running as root, that should avoid the crash with zooming

Re: Chart Problems on Raspberry Pi

I'll try it out tonight as well - will report back.

Dave - it looks like a lot of the pi's are sold out in North America at the moment. Might have to wait until February if you want one.

Raspberry Pi Accessories | Newark

They have Pi kits with everything. But I feel like you would probably have everything you need already.

Hmm .. it's the zooming out and in again that's causing the problem, not current position. I saw that for a while last night but thought it was OK.

Try logging in as root, and running from /

in a terminal:

su root
cd /
opencpn

Re: Chart Problems on Raspberry Pi

I failed - miserably.

Did the git hub thing and tried compile but cmake ../ gave me:

-- *** Build Architecture is armhf
-- *** Staging to build opencpn 3.1.1309 ***
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (MESSAGE):
Could NOT find OpenGL (missing: OPENGL_gl_LIBRARY)
Call Stack (most recent call first):
/usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:288 (_FPHSA_FAILURE_MESSAGE)
/usr/share/cmake-2.8/Modules/FindOpenGL.cmake:153 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
CMakeLists.txt:132 (FIND_PACKAGE)

There is no opengl on a pi ??

As I understand it, OpenGL on Pi/armhf is work in progress, however there must be some libraries there as my cmake ../ returns
-- *** Build Architecture is armhf
-- *** Staging to build opencpn 3.1.1309 ***
-- Found OpenGL...

I just used the latest Raspbian (2012-12-16-wheezy-raspbian) then followed the instructions for Debian here: Compiling - Linux | Official OpenCPN Homepage
(though Thomas suggested earlier in the thread that the git syntax should be "git clone -b master https://github.com/OpenCPN/OpenCPN.git")

Re: Chart Problems on Raspberry Pi

problem manifests itself when using an attached display; zoom in anywhere and all is OK, but zoom out then in again and you usually have a crash.

Interestingly there isn't a problem using X over ssh (XMing on a PC)

.. a data alignment gotcha in s52plib?


backtrace follows:

Re: Chart Problems on Raspberry Pi

Alisdair....

This one looks familiar:
OpenCPN::Tracker All Projects: Tasklist

The Flyspray task is running armel, so unlikely related to float alignment.
I could not make much progress with this one, so far. Still smells like a memory problem to me....

However, the fact that it does not occur over ssh link makes me consider that it might be a latent fault in the gtk or display driver port for arm...

Dave

Re: Chart Problems on Raspberry Pi

Got the latest code and compiled. Got some warnings. New to all this stuff, so I'm not sure if it important.

Code:
/home/pi/OpenCPN/src/chcanv.cpp: In member function ‘void ChartCanvas::OnKeyDown(wxKeyEvent&)’:
/home/pi/OpenCPN/src/chcanv.cpp:3942:24: warning: case label value is less than minimum value for type [enabled by default]
/home/pi/OpenCPN/src/chcanv.cpp:3944:24: warning: case label value is less than minimum value for type [enabled by default]
/home/pi/OpenCPN/src/chcanv.cpp:3951:24: warning: case label value is less than minimum value for type [enabled by default]
/home/pi/OpenCPN/src/chcanv.cpp:3961:19: warning: case label value is less than minimum value for type [enabled by default]
/home/pi/OpenCPN/src/chcanv.cpp:3969:19: warning: case label value is less than minimum value for type [enabled by default]
/home/pi/OpenCPN/src/chcanv.cpp:3970:19: warning: case label value is less than minimum value for type [enabled by default]
/home/pi/OpenCPN/src/chcanv.cpp:4082:15: warning: case label value is less than minimum value for type [enabled by default]
Started up, and OpenCPN took the 2011 CM93 charts no problem. Moving around - everything is MUCH better. No colour errors, which is great. I'm still getting crashes at certain points in the map though. Repeatable for the Boston area - as well as a few others. Would like to help point out the errors. Alisadir, I see you posting this backtrace info. I'd like to help out with this, but am unsure how. Any help? Still not confident with CM93. Would still only use BSB on the water at the moment.

Also - one other problem of note with the pi OpenCPN. I'll try my best to describe. Maybe others can chime in if they are experiencing the same problem. When the mouse pointer hovers over the menu items, an invisible dialog box appears in the X panel. It doesnt show anything - but it does reset the focus, causing the main navigation window to 'flash'. Once in a while it (the navigation window) will even completely minimize, then reopen. It doesn't really effect its use - its just more annoying then anything else. I have no idea what could cause this... but its been present since I first put OpenCPN on the pi.

Cheers
Nick

Re: Chart Problems on Raspberry Pi

Alisdair, DBD

Ignore my last post re: "failed miserably " - I was operating in idiot-mode!
The latest from Git installed fine, took 1hr 5mins to build on the 512 Pi !

Can't see any difference here between that and Alisdair's .deb but that's as it should be I imagine.

Still crashes at higher zoom levels in certain areas.

Cheers

Stuart,

Go to Vector Charts under Options. Select "Mariner's Standard". Now select just a few of the symbols from the menu on the left, e.g. depth area, depth contour, land area and coastline; does that let you zoom in and out?

Alisdair

I compiled today, turning most symbols off in the mariners standard I can now zoom right in and back out into London without crashing. Select all it crashes with a segmentation fault.

AIS works, hilton ferry still running but clipper river buses tucked up for the night

Ran out of usb ports to try gps but will have a fiddle and report back.

Getting loads of "gtk-warning" messages ????

Huge thanks for all the hard work guys.

The gtk-warnings are produced when you use the Option menu and can be ignored; when you hit the zoom problem you'll see a gtk-critical

re. USB ports, if you want more than two you'll need a powered hub - I've had problems running unpowered when I start stacking stuff like wireless, bluetooth and audio dongles. If you've a serial RS232 GPS you can use the GPIO pins with one of these: MAX3232 RS232 Serial Port To TTL Converter Module DB9 Connector w Dupont Cables | eBay
