Weather routing: GRIB: fail

Hi,
I am using opencpn 5.0 on a raspberry 3+
It works great!!
Except for computing the route in weather routing. I get the message: Grib: fail.
It does work for climatoligy but not for Grib files.
I use zygrib and also tried other gribs.
The windvanes are visible on the map.

Anyone any ideas?
Thanks in advance
Onno

Re: Weather routing: GRIB: fail

Windows 10 - Just downloaded from Opencpn.org Downloads, the most recent wxroute 1.13.0 and installed into a fresh installation of Opencpn5.0 and it works out of the box.


Created new start and end points, fresh grib, created a new config, and hit compute.
It works out of the box.


What version of Opencpn? What version of wxroute?
What type of grib file? Screenshots of all basic settings please. You must be more detailed to get good help.

Re: Weather routing: GRIB: fail

use weather_routing 1.13 and make sure your grib_pi is current.

Re: Weather routing: GRIB: fail

Hi Rick,
Inhave version 1.10 of weather routing.
I tried to update/ upgrade but got the massage this is the highest version
See attached picture of update message.

Not sure if version 1.13 exists for linux/openplotter. And of so i dont know how to install other then used commands.

So i may have to wait till available
Do you know if version 1.10 should work?
I find it strange the computation works for climatology but not for Gribs. ( i have version grib plugin 4.1)
If you think it should work with version 1.10 i will send you my settings and gribfiles used. It could vert well be i have a wrong setting somewhere.
Thanks for your help sofar
Onno

Re: Weather routing: GRIB: fail

You are using openplotter. I think it should work, but this was a known bug awhile ago. You have two choices: learn how to compile and build your own (not hard in linux, generally) or ask openplotter to update it. Look in the opencpn developers manual under linux and ask openplotter how to compile it..

Re: Weather routing: GRIB: fail

Thanks for asking
Seems openplotter will not update so will have to do it locally.

Re: Weather routing: GRIB: fail

Take good notes for how they do it, so you can do it and so we can put it in the wiki for others!


"Building plugins for OpenPlotter"


Just post a text or doc file here and I'll find a place for it.

Re: Weather routing: GRIB: fail

Below the reply i got from sailoog.
I dont know any developers to forward this to.
Can you help?
Cheers Onno

====================
Antw.:⁨ [General] Update opencpn plugin weather routing 1.13⁩

Hi Onno,

AFAIK there is not version 1.10 for linux yet, just for windows. This is the repository where it should be:

https://launchpad.net/%7Eopencpn/+archive/ubuntu/opencpn/+index?batch=75&memo=150&start=150

This should be reported to developers and repository maintainers, could you do this?

Regards

Roberto

Hi!
I am running openplotter and opencpn (5.0) on a raspberry pi. Itnworks great,

However r the plugin weather routing gives an error when computing: " GRIB:
Fail"
According tomopencpn i need to use vesion weather routing 1.13 instead of
1.10. When running an upgrade command for this i get the message that 1.10
is the highest version.

Can you make weatherrouting 1.13 available so i can install it?
or do you know of another way to fix this issue?

Thanks Onno

Re: Weather routing: GRIB: fail

Hi,


We can not install compiled plugins in OpenPlotter because they could not be updated when a new version is released, plugins have to be in the opencpn repository to be installed and updated when necessary.


I have reported this to ppa maintainers here: oesenc plugin missing from PPApencpn repository - Cruisers & Sailing Forums
