Hi,

First thanks for the fine piece of software.

I would like to report some small problems I noticed.

Running OpenCPN on Ubuntu 11-04

Those two have been reported before;

- I have the toolbar that moves to the center of the screen when closing the toolbox.

- I have the sound problem but the padsp workaround works for me.

I have not seen anything about the next two:

- When closing the AIS Target list, the click is sent to the map and the map centers where the closebox was.

- The Autopilot Output Port does not stay put.

Let me explain this last one.

I am using USB to serial converters to connect the GPS, Autopilot and AIS. If I run OpenCPN with the converters not connected, the Autopilot output port reverts to NONE. The GPS and AIS ports selection stays.

In addition, I have written udev rules so that the USB to serial converter used for the GPS gets a symlink called gps, the one for AIS is called ais ant the one for the AP is called nmea. So for the GPS data source I enter /dev/gps, for tha AP output port I enter /dev/NMEA and for the AIS port I enter /dev/ais.

It works perfect for the GPS and AIS and I do not have to worry about the order of USB connexions but the AP output port will not accept /dev/nmea.

Thanks for reading.

I'm having the same installation problem with Ubuntu 11.04 and OpenCPN 2.5. English version of both. I tried Thomas' file, and didn't get any errors. It said "Installed" at the end, but I can't find the OpenCPN application anywhere.

Disclaimer: I just decided to try Ubuntu yesterday, so it's quite possible I just don't know how to look for it properly.

Welcome to linux!
There may not be an icon to click, but rest assured -OpenCPN is installed.
Go to Applications -> Accessories -> Terminal. You now have access to a command line. Just write "opencpn" (without ") and then press "Enter" aka "Return".
OpenCpn will now start. To start with sound enabled just write "padsp opencpn" instead.
Read more about Ubuntu on the web and create your own start icon or menu entry, if you like.

Got it! Thanks Thomas!!!

It works fine.

I did two things, I recompiled the kernel enabling Alsa OSS emulation layer and I downloaded your build of OpenCPN. Here is the result matrix:

Original kernel and original OpenCPN build: exit with previously reported message when sound output is attempted.

Recompiled kernel and original OpenCPN build: sound works OK.

Original kernel and your OpenCPN build: no sound output but no program exit either, no messages on console.

Recompiled kernel and your OpenCPN build: sound works OK.

Of course enabling Alsa OSS emulation layer brings its own set of issues, now the first app that grabs audio output holds it exclusively. IMO on a general purpose computer this might be a problem, but on a navstation it is mostly a non-issue. (Another side effect is that now JWX is able to access an uninterrupted stream of audio data while with original kernel it would 'hiccup' regularly and loose weatherfax data.)

Edit: forgot to report another glitch. In Toolbox > Vector Charts the list of map objects for Mariner's Standard view is empty.

Thanks yet again for a great update to a terrific product! Excellent timing too as we're heading off to Mexico.

I don't seem to be able to find the newer versions of the plugins for weather and dashboard, I've looked at PlugIns | Official OpenCPN Homepage - can someone post a link please?

Cheers and thanks again
Paddy

Paddy...
The Dashboard and Grib plugins are part of the installation package, you don't have to download them separately.

Thanks Pavel.

Mine still say version 1.1, is this the latest? I thought the weather plugin could now display synoptic charts?

Cheers
Paddy

Care to share or give a hint on how you made those rules.

Yep, it is the latest. It's a Grib plugin, so it displays the grib data, not any kind of charts.
If you want synoptic charts, you have to convert them into chart files and treat as charts. I'm automatically calibrating a couple of them and make them available for download at the following links:
Index of /opc
Index of /adriatic-weather
Index of /21ows
Good when you have decent internet connection, too much data to pay for if you are connected via satellite...

I wrote those rules with the help of the udev man pages, udevadm man pages and this page: Writing udev rules

For example if I plug a USB to serial converter that appears as /dev/ttyUSB0

$ udevadm info -a -p `udevadm info -q path -n "/dev/ttyUSB0"`

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

With that information I could write a rule like this:

You save this in a file in /etc/udev/rules.d

Here is my rules file: /etc/udev/rules.d/serial ports.rules

# Creates a unique link for each serial port
#
# AIS Receiver
SUBSYSTEM=="tty", SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="A100eeux", SYMLINK+="ais"

#

#
# IC706 radio tranceiver
SUBSYSTEM=="tty", SUBSYSTEMS=="usb-serial", DRIVERS=="edgeport_4", ATTRS{port_number}=="3", SYMLINK+="ic706"

Ok?

I think I must have misread a posting some while back about the weather plugin. The BSB/KAP versions of the synoptic charts look like a good way to handle it.

Thanks again
Paddy

ratsea · 03-08-2011, 01:07

Great work, and thanks to all concerned.

And a question, should I be able to see the AIS data on the GPS/NMEA data stream with a combined NMEA input? It is very useful for checking that the AIS receiver is working OK. (OS=Win7)
