1. I try to make a route from Falmouth to LasPalmas with climatology. It ony gives state:failed on configurations window. Any advice on how to make this work?

Okay,
OS ?
Linux Mint 17.3 Cinnamon 64-bit, current updates

OpenCPN version ?
4.2.1724

Weather_routing version ?
options->plugins says 1.82

Climatology version: 1.2

OpenCPN debugger output:

GRIB_TIMELINE_REQUEST : CLIMATOLOGY : {
   "ClimatologyCycloneTrackCrossingsPtr" : "0x7f1f7adbd130",
   "ClimatologyVersionMinor" : 2,
   "ClimatologyDataPtr" : "0x7f1f7adbd1f0",
   "ClimatologyWindAtlasDataPtr" : "0x7f1f7adbd160",
   "ClimatologyVersionMajor" : 1
}
CLIMATOLOGY_REQUEST : CLIMATOLOGY : {
   "ClimatologyCycloneTrackCrossingsPtr" : "0x7f1f7adbd130",
   "ClimatologyVersionMinor" : 2,
   "ClimatologyDataPtr" : "0x7f1f7adbd1f0",
   "ClimatologyWindAtlasDataPtr" : "0x7f1f7adbd160",
   "ClimatologyVersionMajor" : 1
}

It runs 3 seconds, and gives "failed"

"Weather routing configuration"

Courses: 0-180-5 degrees
Constraints: default
Time step: 12h 0m 0s
Options: Basic: selected detect land, currents
Boat: default boat.xml
Data source: Climatology -> most likely

Cheers,
JCF

Okay, when deselected "detect land" it runs fine... route is bollocks, though. (runs through northern Spain) "Currents" selection has no effect.

I think I have OCPN "high resolution" base chart in use, if that's a factor. Also, loaded channel charts.

Cheers, JCF

btw: is boat.xml file's editing covered somewhere on this 63 pages thread :d I get somewhat silly upwind/downwind speeds...

OK, JCFLander. If you can, use Opencpn version 4.2.0 and Pavel's fork of weather_routing v1.83 which is behind sean's fork. Or perhaps just use the one on the download page for v4.2.0.

Those should work, I have tested those in Win10 see notes below.

[rgleason]

Sean, I now have Windows10, MSVC++ Debug working with Opencpn v4.2.1 most recent Weather_Routing_pi and Grib_pi. When I run in Debug mode the routing "Fails".
Do you have some suggestions for where I should put breaks that are meaningful?

1. How do I determine if the problem is that Windows Weather_routing is not receiving or reading the Grib file?

2. How do I determine if the problem is that the Weather_routing Configuration File is not working, is misconfigured or something?

3. How do I determine if the Polar file is not found? -I think there is a message for this one.

Perhaps in Preferences if we could just opt to turn on some debugging messages that say something like:
1. Configuration is OK, or Configuration is incomplete
2. Polar file is found/ not found.
3. Polar file is acceptable/not acceptable.
4. Grib file found/ not found.
5. Grib file format is acceptable/ not acceptable
6. Reading Grib file or Not reading Grib file.
7. Grib start date/time and Routing start date and time are OK or don't match.

What have I missed? I am sure there is something.

I am now wondering if the problem is that the plugin no longer reads the grib files!
Because I don't think it is the configuration file now, but maybe it is because there have been many changes to that area....

First we need to isolate it to
1. Is it a Grib problem?
2. Is is a Configuration problem?

[rgleason]

When I build the plugin there is no version.

weather_routing_pi-.-win32.exe

What does this mean?

[rgleason]

The Windows version of the current github
https://github.com/seandepagnier/weather_routing_pi
Correct cursor calculation for the other side of the world.
https://github.com/seandepagnier/wea...7d3fd55518b3dc

fails in Opencpn v4.2.1
----

The version that does work in Opencpn v4.2.0 is
Pavel's fork which is 21 commits behind, dated May 9
https://github.com/nohal/weather_routing_pi
the commits previous to this one are
- Update translations
- Adjust grib_pi version to support OpenCPN 4.2.1706+
- Adjust the climatology version.

This is available on the Download page
PlugIns for OpenCPN 4.2 | Official OpenCPN Homepage
Weather Routing v1.82.1, Released 2016-03-04

So, I believe it might run under the Opencpn 4.2.1 beta, but I have not tried it.
It does work in OpenCPN 4.2.0 and 4.2.1706

Pavel updated Weather_routing for a new Climatology Version on March 4
https://github.com/nohal/weather_routing_pi/commits/master

I believe it uses an updated version of climatology.
Max major =1
Max minor =2
Min major =0
Min minor =10
Is it this version 1.2.0.10 ??

---

On the download page PlugIns for OpenCPN 4.2 | Official OpenCPN Homepage
ClimatologyClimatology v1.2, released 2016-02-25

So the download page has the correct version.

[rgleason]

The current beta version of Weather_routing is on File Thingie directory 4.4 PI Win directory.
This plugin only works wwith Opencpn v4.4!!!!

Two routings below are with a grib and climatology.

New beta version for O4.4 see

Weather_routing working with ODraw Guard Zones. It works beautifully, and considering the extra calcs it is quite fast. First one is just one GZ+Grib+Climatology, second one is 2 GZ + Grib + Climatology with Land checked and 1 hour intervals. This is quite a tour de force of plugins all working together.
- Weather_routing_pi
- Grib_pi
- Climatology_pi
- ODraw_pi

Thank you Sean and Jon for two great plugins!

[Silver_Surfer]

Is the Grib_pi file along with the other files you list downloaded from the main opencpn site or a particular file share site?

Would have liked to give WeatherRouting plugin another try, but unfortunately I must report the following two errors :

1/ Mac OS X El Capitan v10.11.6 and OpenCPN 4.4.0 : plugin package v1.82.1 will not install, with message "The installation failed". I tried manually removing the plugin folder in the OpenCPN app and the plugin preferences folder as well, but no luck.

2/ Mac OS X Mavericks v10.9.5 and OpenCPN 4.4.0 : plugin package v1.82.1 does install and run, but computing fails with message "Grib plugin version not supported". That is the standard Grib plugin v4.1 installed with OpenCPN 4.4.0.

Too bad, it looks as though this plugin does not like me trying it. Anything obvious I may have overlooked ?

Nothing obvious..... The plugin download page at OpenCPN.org was replaced by an older copy or copies in the last day or so.

You need "weather_routing_pi-1.10.1" for the Mac. The Windows build of this release works well with (Windows) OpenCPN 4.4.0 for me. The Mac builds of OpenCPN 4.4.0 and weather_routing_pi-1.10.1 should work.

The version 1.82.1 of weather routing is actually older than 1.10.1.

Mac OS X is not very well supported neither by the main software OpenCPN nor by the plugins. Reason might be that the underlying wxWidgets libraries for the Mac OS X port are still in development and are not as stable as for Windows or Linux.
Therefore I have made my own version of OpenCPN and plugins for my Mac with El Capitain. Several plugins I have heavingly changed but not all. Weather-Routing is one which I left aside. Others like BR24radar works great without changes mainly because the developers of BR24radar also use Mac OS X.
So I guess the goal to have a software for any operating system has failed.
In the future it will be more and more difficult to use free software for newer operating systems like Sierra from Apple. The risk to get malware is too high and companies like Apple don't want to lose their reputation.
