KML Overlay Plugin

[SethDart]

Pavel,

Thanks for the build.

This is a very early version. Objects are rendered even if they're out of the viewport. There's no optimization currently. Some point are computed to the left outside of the display while others are on the right, hat's why there's a straight line in between. I'll have to figure the geometric algorithm to find if the object crosses the display or not to figure if I render it or not. There are probably objects that crosses the -180/+180 line that are rendered incorrectly.

There's still a lot of work. I'll probably start with styles, to handle color and transparency. Then GroundOverlay. I'm still thinking about the possible need of expanded selection of objects inside kml (for now each kml file is either visible or not, you can't toggle objects one by one. but I already handle visibility parameter so if an object is described as hidden, it's not drawn)

Comments/suggestions/patches welcome ;-)

still no luck on XP

LeaseOnLife,

Do you use straight 2.5.0 release from opencpn.org or did you compile it yourself?

2.5.0 from opencpn.org

LeaseOnLife...
Weird, very weird. I've just tried it on my little Atom XP machine and it runs OK. Didn't you forget to copy libexpat.dll to the OpenCPN program directory? That way I was able to make the loading fail but with a different error (126: module not found)

Out of ideas

libexpat is where it should be....

If nobody else has this problem, then don't focus on it... Waiting for a 2.6.x version with ChuckSK patch for rendering CM93 on the ICW without crashing...

[SethDart]

Do you know who built official OpenCPN windows package? Is it you Pavel?

We'll have to figure exactly which options were enabled to reproduce exactly the same for our build environments.

When I faced these errors, replacing C:\Program Files\OpenCPN\*.dll by those I built with wxWidgets made the crash disapear. To me it's a wxWidgets compatibility problem. OpenCPN ran fine with both... - scratching head -

[nohal]

Nope, I suppose Dave built the package - I'm building just the 2.6 betas.
Very nice specimen of a DLL hell

I've got exactly the same problem with XP - see my post #24.

I wonder if it is anything to do with trying 2.6.1310 and then removing it before reloading 2.5.0?

It works fine on W7 on my desktop machine.

I put "kmloverlay_pi.dll" in plugin folder and "libexpat" in root folder (proramfiles/opencpn2.50/Win7). But when I open the toolbox I see nothing changed in my plugin list, no KMLOverlay plugin seen between the other plugins.

GNU/Linux users. Just download the source to your codebase. Install libkml-devel from your distro. Run make and it should just work.

Ok...just build it. Nothing to be found in the plugin tab.....sorry. Perhaps some further instructions?

Can you check the logs to find any relevant info?

Are you building stable (2.5.0) or latest beta (2.6.*) ? Platform (windows, linux -which?-, mac)?

If you build for stable, you must revert one commit from the plugin source (the one that make necessary changes for the plugin to work with beta)

$ git revert fbfe7093e574111aebecf218820d229412b17749

Used the referenced source from here: https://github.com/OpenCPN/OpenCPN/tree/KMLOverlay and build on Ubuntu 11.10 turns out this source produces a beta 2.6.* build. The package (zip file) is identified as OpenCPN-OpenCPN-0c3a96a but there is noting in the logs. My thinking here is that this is the wrong source, yet the update entry for kml overlay is present. strange. Nothing in the logs.

OK checked the source and its the wrong one. Nothing there. My error but used the link provided. Can you point me to the correct source base pls so I can run it again.

/ch

[sailias]

Ok...sorry to pester. I should add I downloaded the zip file from the referenced page which I guess links to the latest beta and the kml branch. If someone would be so kind and send me the git syntax to grab the appropriate source I would be happy to test it. So far my attempts with git to grab it have not been successful...lack of experience with git...

Best regards and thanks
