I used version 1.3.6 when cruising last summer and was pleased with the results.

Version 2.3.1 installs cleanly, but when initiated it crashes with an event type BEX while starting to display its home screen. Version 2.3.0 did the same thing. I've installed the prerequisite Visuall C++ Redistributable Package with no affect.

It is running on an up-to-date version of XP SP3 (Tablet Edition) with 3 GB of memory.

Ideas on how to resolve this?

Can you publish your logfile? To find it read Installing OpenCPN | Official OpenCPN Homepage, scroll down towards the bottom.
Rename the logfile by adding ".doc", to avoid problems with uploading to this Forum.

Happy New Year to all OpenCPN users!

i've also had several issues with C++ Redistributable. It's 'cause i build my own computers and install from the OS on up. i use XP pro SP3.

there are several different versions of C++ Redist. 2005 (with a security update), 2008 and 2010. also note some are 32-bit (x86) and some are 64-bit (x64) and there are multiple versions within the 2008 releases and within the 2010 releases. and i'm not sure i'm even interpretting it all correctly.

2 days ago I rebuilt the system on my Intel D510-based 'puter. 2010 version says on some download sites that it works on x86 machines even tho it's named x64. wouldn't work for me.

i installed the 2008 x86 and bingo all is good. (i didn't find the 2010 x86 in time, so i can't speak for whether that would work or not. i couldn't find it on the microsoft download site but found it elsewhere. i'll try it next time.)

anyway, known good at least for me is C++ Redistributable 2008, version 9.0.30729.17 which i donwloaded from downloadsource.net

but if that doesn't work for you, try another version. sooner or later one will work.

any other wisdom on versions or installations from others?

I found a log file, but all of the info in it is from the previous version, 1.3.6. So either 2.3.0 didn't log anything before it crashed, or there is another log file that I haven't found. It crashes while presenting the OpenCPN home screen, so I can't check the About tab.

The C++ redistributable (9.0.30729.17) is same as BlueGillBoy. Both OS's are the same (XP Pro SP3), although I'm using a tablet which has never caused an issue in the past.

ColinR,
there's a good chance you found an old logfile as the location changed since 1.3.6. The 2.3 logfile on XP should be in All Users' Application Data folder - unfortunately the path changes with language version, but it should always be similar to

C:\Documents and Settings\All Users\Data aplikací\opencpn\opencpn.log

- for sure not the same unless you have a Czech version of XP installed...

Other way to find it is to use something like TotalCommander and search the whole hard drive for opencpn.log (do not use Win's built in search as it sometimes tries to be smarter than you and doesn't look in "system" folders)

If OpenCPN crashes during the display of the main window, there for sure should be log entries already.

Thanks for the help - it is now up and running.

I found the 2.3.1 log file (which was indeed a different file from the 1.3.6 log file) and it showed a warning on the chart database. I reinstalled 1.3.6, did a chart db rebuild, then reinstalled 2.3.1. No change. So I reinstalled 1.3.6, manually noted my settings, and then reinstalled 2.3.1 with new config files. This solved the problem. Funny that 1.3.6 was happy with the chart DB but 2.3.1 crashed on it.

Thanks again for the assistance. I look forward to getting out on the water with the new version this spring.

Hi there,

for the last 7 months i have been busy writing a dashboard, comparable to polarcom but with some extras like sailing polars. Dashboard is now 95% ready and 100% functional. So now i would like to take the next step: interfacing it as a plugin to open-cpn. I'm searching to find some documentation about the DLL header structure, but to my dispair i don't find anything. Could you help me with e.g. a link to the demo_pi source code ?

[cagney]

The source code for the latest stable release is available here:Download OpenCPN | Official OpenCPN Homepage

But as a developer you are better of following the directions for developers here:Developer Manual | Official OpenCPN Homepage
This includes setting up the tool chain and downloading the source through Git an compiling

You can also have a look at OpenCPN | Download OpenCPN software for free at SourceForge.net.

I'm looking forward to your contributions to OpenCPN.

Good Luck

Thomas

As far as I can remember you wrote the dashboard in Lazarus - the following link could be useful: Lazarus
Wish you the best of luck in this area that looks a bit unexplored to me.

Hi Pavel,

this should work. Since the document (which i already knew) some progress has been made. I can now declare in functions & procedures in 'c-style', e.g.
function RenvoiChaine(pChaine: pChar): Pchar; cdecl;
I''l keep you informed.

Hi all..

I have a weird AIS target positioning problem with OpenCPN and a newly converted .kap chart. As can be seen from the attachments,the AIS targets have correct positions in both Fugawi ENC and SeaClearII. The first OpenCPN display has wrong positions which are made worse by panning/pulling the screen with the mouse. The targets change position when moving the chart. I have actually encountered this previously on a few occations. Suggestions anybody?

Tore

[sinbad7]

Ref my #686

All my calibrated and converted .kap charts have a strange behaviour in OpenCPN.

When moving the chart view holding down the left the mouse button,all AIS targets as well as routes are moving independently of the chart. i.e. they do not follow the chart movements but seem to have a life of their own.

This phenomena does NOT happen in SeaClear or Fugavi ENC.

This is a serious misbehaviour which can cause accidents and should be examined soonest possible.

The first example shows the correct route path,the second after dragging the chart to the left.

Tore

I cannot repeat this problem with routes I have tested on various charts.They all behave as expected.
Anyone else having this problem?

Thomas

[sinbad7]

I wonder if it has something to do with larger than screen maps made up from bitmap tiles?

I presume a screen dump of a chart is a screen dump and a bitmap without any other hidden features? i.e. all bitmaps should behave identically.

If you want to test it out you can download the chart here:

Check your geo-referencing! The PLY:s are badly skewed, as can be seen above.
