OpenCPN Version 5.7.1 Beta Test #3

[P_Dub]

Good Done. There are some plugins incompatible shown when openning and it freezes the program if you don't reply OK. I tried to remove them and it is not always done. But on the overall it seems OK.

1. What CAN hardware interface are you using to feed the HP-550 laptop?
From the candump it may be slcan?
2. We will need a slightly longer snip than 5 secs to debug the stream. Maybe a couple of minutes?


FWIW, I am running Rusoku TouCan USB socketCAN interface on generic Kubuntu desktop, and having no trouble with 10Hz. GNSS data. So I do not think that data flooding is the trouble. We have tested much busier nets than this, including multiple high speed GNSS receivers on a single net.



Thanks

Good! Dave I will add this to fonts and tides in manual. Thanks.

Dave,
thanks for your interest.

I'm using a USBtin card (https://www.fischl.de/usbtin/) that has been serving me fine for over 2 years now. I've used both TwoCan and Signal K without any problems but is, as I need NMEA 0183 RMC messages for my VHF, forced to use SK. Testing 'socketCAN' was to verify if that could be used instead.
The interface is, as you guessed, slcan0 as described by fischl, completely standard.

The shutdown problem is just that, OpenCPN not shutting down properly when using the Garmin GPS24xd and socketCAN as the only source. Using TwoCan or SK generating NMEA 0183 works just fine. Using the OpenCPN normally is also ok but clicking the red 'X' closes the OpenCPN screen display in a tenth of a second leaving a white background for another half a second before shutting down O completely.

Could it be something 'Garmin proprietary' causing this? I've seen that before.
A longer candump (just over a minute) is attached.

LennartG...
Are you building OCPN from source? We have a patch that might relate to your observations, tested relevant on other platforms....
Thanks
Dave

[LennartG]

Dave,
never built OpenCPN from source, ever. Don't even have the tools on that machine. I will however see if I can set it up tomorrow morning. Wish me luck!

The latest builds have some additional features for sending items to peer OpenCPN sessions in the same net:


- send Waypoints and Tracks from the Waypoint & Route manager
- send multiple items from the Route, WP and Track list


Works well for me between W11 and macOS peers.

LennartG...
These days, thanks to Leamas, building OCPN on linux is pretty simple.

sudo apt-get update
sudo apt-get install git
git clone https://github.com/OpenCPN/OpenCPN.git
cd OpenCPN
sudo apt-get install devscripts equivs

mk-build-deps ./ci/control --install --root-cmd=sudo --remove
sudo apt-get --allow-unauthenticated install -f

mkdir build && cd build
cmake \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DCMAKE_BUILD_TYPE=RelWithDebInfo \
    -DOCPN_USE_BUNDLED_LIBS=OFF \
    ..
make -sj2

sudo make install

Good Luck
Dave

Good news: looks like the recent commit to "Correct plugin destruction logic on shutdown." fixed the crash I was seeing on exit when connected to can0 and dashboard_pi was enabled. (Raspbian/32 on Pi4)


btw, on the n2k side I have a 10hz gps+heading+attitude and a 5hz speedo and 1hz attitude+depth+temp. (Airmar DST810).
Also 0183 wind instrument which Signalk sends 0183/signalk/n2k.

sanner...
That's great. Corresponds exactly to the crash analysis that we did.


Thanks for the report.

Dave,
compiled the latest git version (thanks for the excellent step-by-step description) and now OpenCPN shuts down properly (in spite of the Garmin specialties?).
Tested 15+ times without any problem.

Sorry, I've been posting on the Beta Test #2 thread, but should probably have been posting here. The version I'm running is one I downloaded yesterday that had just been uploaded yesterday afternoon, so likely it is v3+?

My OpenCPN version is 5.7.1+f64a83a on Windows 10

Reporting specifics on 2 problems associated with track/layer files.
- Track detail screen crashing OpenCPN on some tracks
- Routepoints with shared flag on show up on a layer that is hidden when O
first opens.

Screen shots, details, and how to reproduce are here:

The last couple of posts on that thread.

One big question:- what version works OK on Windows 10 without bugging and or freezing since the 5.6.2 ? in order to wait for 5.8
It would be appreciated. Many thanks.

P_Dub...
As always...
1. If you need a stable version for critical at-sea navigation, use O5.6.2
2. If you would like to participate in OCPN Beta testing, we welcome you and your feedback. Beta testing comes with the understanding that the official Beta test objects may be unstable, and so unusable for daily navigation.
3. If you would like to be on the "cutting edge" of the development process, the daily builds are available from Cloudsmith for anyone to download and install. These daily builds are possibly less stable that the "official" Beta builds, but may be useful to particular configuration testing. And the developers appreciate that feedback, positive or negative.


Thanks
Dave

Many thanks for the quick response. Will try a parallel installation to see again tomorrow. Which would recommand? I had bad experience with some.
