Trouble starting OpenCPN

[Schnapsy]

Hello,

Today, at my home, I started OpenCPN.
No card installed, all additional plugins are inactive. (see attached pictures)
No connection (com port and UDP) appears in the dedicated tab.

I enclose the ini and log files.

For information, I installed two days ago the WatchDog plugin by setting it to trigger in the absence of GPS signal.
As it was triggered each time (PC at home), I finally uninstalled this plugin because even after removing the alert settings, I had a regular sound that was triggered (NB: despite the uninstallation of the plugin Watchdog , the small steady sound continued, so it was probably not bound).

What can be the origin of this problem knowing that it is the computer that I take on board to navigate and which therefore understands only few programs ?
Win10
OpenCPN 5.0

The reason that...

No connection (com port and UDP) appears in the dedicated tab.

is that no connections are configured in the ini file.
You have to restart from the beginning and reconfigure your previous settings.

Yes, that's what I did ...

But my question was :
Why, while everything is well configured and that the PC has been used for several trips at sea with OpenCPN connected that worked very well, why suddenly (during a restart) nothing appears anymore?

No one will ever be able to give you a satisfactory answer to that.
OpenCPN does not, without reason, loose it's settings. I have on occasions thought that to be the case, but it has always boiled down to my own screw up.
I have learnt the hard way always to save a good ini/config file as a backup.
If you can produce a repeatable way to loose .ini files settings, then we would be looking at a bug.

Maybe because

despite the uninstallation of the plugin Watchdog , the small steady sound continued, so it was probably not bound).

From your logs it's like many opencpn were running at the same time and at some point one trashed the configuration file.

Could be a sound handling related bug. ie O seems to exit but doesn't fully.

Schnapsy,

I think Didier hit the button on the head so to speak. Opencpn using a single configuration file named opencpn.ini unless run in Portable mode. When you try to run two instances of OpenCPN at the same time, they are thrashing to write changes to the opencpn.ini or opencpn.conf it is no wonder your's got trashed. Note: I have had two different versions of Opencpn running at the same time by accident, but I always shut one down as soon as I see that.


Others may have more current/accurate information on this.

I don't think so.
OK there are many back to back instances of O, but they are all terminated with a "opencpn::MyApp exiting cleanly", before the next one starts. Trying on Linux where it's possible to run multiple instances, and looking at the log file, the stream from a new instance just blends in to the previous one. Stopping one instance results in a "opencpn::MyApp exiting cleanly" appears anywhere in the stream of messages from remaining instances.
It's not supposed to be possible to run more than one instance on windows, so if you are right, there must be a code path available that is "out of control", and "opencpn::MyApp exiting cleanly" is not true.

Now, how this is possible I have no idea, but the sound subsystem seems to be involved.

[cagney]

Well I asked for it!

You are correct!

Hello,

I followed all your interventions with interest even if it is difficult for me to answer.
In no case was Opencpn launched twice at once (opencpn opens automatically when the computer starts with a batch in the boot session).

That being so, I have reinstalled everything and made a backup of opencpn.ini.

Monday, in the marina,I found that several times opencpn froze, nothing worked and I had to turn it off on a request from windows.

I attach the log files.
This is the date of 24/06 and what is disturbing is for example lines 2771 to 2773, or 3125 to 3132 in the log.log file.

If necessary, I will uninstall and then reinstall Opencpn, but I would like to know the origin of these troubles.

After reading this post "http://www.cruisersforum.com/forums/f134/opencpn-crashes-constantly-219449.html", I must say that Opencpn only freezes since I connected my sonar on a RS-232 USB Breakout Cable (https://www.milltechmarine.com/USB-B...ble_p_220.html).

Are you absolutely sure you have this wired up properly?

Yes, I have been using this type of cable for at least 5 years. ( https://www.schnaps.fr/articles.php?...=311&tconfig=0 )

It worked perfectly on OCN 4.8 and seems to work on OCN 5.0 since the sonar data are displayed correctly.
I do not think this cable is causing the problem (I just explained its installation, just in case) but as a new driver has been released, I will install it this WE.

However, I do not think that Opencpn freezes because of this cable ...

Hi,


Do you remember if the working version was 4.8.6 or 4.8.8?

Very good question...
For version 4.8.6, it's certain ...
However, for version 4.8.8, I'm not sure because I had - meanwhile - removed these cables usb / serial and replace them with a multiplexer.
