Weather Routing

[rgleason]

Sean Thanks very much will try it in the morning!! Oh boy.

Sent from my SCH-I545 using Cruisers Sailing Forum mobile app

I tried it several times using Standalone setup with the attached results.

The full output file from cmake --build . --config release was cut off probably due to memory use. I can attach an output file from an attempt to build with MSVC if that will help...(it has the full ouput, but may be somewhat different because of the cmake files, you'd be the one to advise.)

[rgleason]

Standalone WMM_pi has compiled using MSVC command line and does run in Opencpn!

[rgleason]

Today I tried standalone compile of Weather_Routing using opencpn.lib from version 3.3.1618 The results are attached, fewer errors but still too many.

Should I be using opencpn.lib from the Optimized version????

It seems like tinyxml.h does not have 1401 lines!! So something might be wrong with that file?

[rgleason]

Ok I got on sourceforge for tinyxml and the tinyxml.h file is 64kb instead of 9kb and it has line 1401 plus many others. Copied that to my wx_route src/tinyxml/ dir and the number of errors was reduced. I downloaded tinyxml 2.6.2 I believe. I hope that is correct. It is the most current.

[rgleason]

Ok by copying over using Sourceforge tinyxml v2.6.2 tinyxml.h and tinyxmlparser.cpp files to the src/tinyxml/ directory, I go it to compile successfully.

There are 30 unreferenced local variable errors. What are those and is that something you should know about?

I will test separately. Attached are the two tinyxml files used, plus output.doc

Ok, after copying the compiled (attached) weather_routing_pi.dll to plugins directory for compiled Opencpn 3.3.1618 I ran a recent grib with the compiled release grib_pi v3.3.1608) and Dashboard release v3.3.1608.

The message after "Compute" is "Grib Failed"
Sean please explain what this means, so we can get it fixed.
Does it have something to do with the "Moving Grib" implementation in Grib_pi? Should we test earlier grib_pi versions to see if one will work with the current weather_routing_pi?

Thanks

Tried to attach grib_pi.dll and weather_routing_pi.dll and the grib used, but they are too large. Please see the Opencpn 3.3.1618 directory on the Opencpn Beta File thingie here: File Thingie 2.5.7 rguser, rgpass I will upload shortly. (take doc off)

[rgleason]

It is VERY nice to have it actually compile. It actually feels like we are getting somewhere, but I do wish it did not result in "Grib Failure"!

Matt, Neptunes Gear also noticed and asked about this.

[rgleason]

I just tried a Grib without a moving vector, and with only WIND. It still fails with "Grib Failure"

[rgleason]

By going back to previous gribs, I think we have found somewhat of an answer.

grib_win32_pi17_v220_ov331419_pi.dll Version 2.2 Lists 4 basic data types and it works.

grib_win32_pi_v22_ov331606_pi.dll.doc Versions 2.2 Lists 12 basic data types and does not work.

grib_win32_pi_v22_ov331618_pi.dll.doc Version 2.2 Lists 12 basic data types and does not work.

First I think we definitely need to have successive version numbers or even sub versions to keep the straight when loaded in program.

Perhaps Ptizef can make the huge enhancements to Grib_pi be compatible with weather_routing with this information? Weather_routing just uses wind and wave data basically, maybe it has something to do with record order or something. Some discussion with Sean would help I think, but we know the problem is associated with the new data types.

You will have to go to Opencpn Beta File Thing
File Thingie 2.5.7
use rguser rgpass
because the file grib_win32_pi17_v220_ov331419_pi.dll is too big.
You want Folder 3.3.1419 Plugins-Win-Opencpn

I do hope this can be fixed easily.

[seandepagnier]

Interesting that copying sourceforge tinyxml works. Good job.


I already explained that pitzef inadvertently broke weather routing, but I fixed the problem in the optimum branch, so you can use the grib plugin from there.

[rgleason]

Thanks Sean, I will get that running too!

Summary: For now because of the incompatibility between current v3331618 grib_pi and current weather_routing you can do the following:
Opencpn 3.3.1618 (beta) download or compile
Weather_routing_pi for 3.3.1618 (found on Opencpn Beta File Thing (see above)
Grib_pi earlier version from 3.3.1418 (also found on Opencpn Beta File Thing)

Sean would like to see us using Optimized O'cpn where he has a working combo for weather_routing all set up.

Hello there,

Many thanks for working on this plugin and reading and replying to my message.

I'd like to test this useful plugin.

Any one there that can give me a link to the latest release and a quick readme on how to install it on a win8 64 laptop?

[rgleason]

Download OpenCPN | Official OpenCPN Homepage

and Opencpn Beta File Thing for the plugins (as above)
Please see the Opencpn 3.3.1618 directory on the Opencpn Beta File thingie here: Opencpn Beta File Thing rguser, rgpass (Take doc off)

You need the following:
Opencpn 3.3.1618 (beta) download or compile
Weather_routing_pi for 3.3.1618 (found on Opencpn Beta File Thing (see above)
Grib_pi earlier version from 3.3.1418 (also found on Opencpn Beta File Thing)
Take the "doc" off these are dlls.

See Getting Started | Official OpenCPN Homepage
Opencpn is 32 bit so it installs in Program Files (x86)

Put the plugins in the plugin directory.
You'll need charts download from Noaa or look at these sources
http://opencpn.org/ocpn/All_About_Charts
Good luck.

Thank you Rgleason,

I am an OCPN old time user (5y) and already using the latest version.
I will download and install the plugin and get back to you with results.

BTW, the latest Beta on the site is 3.3.1606 ???
