Weather Routing

[fogmachine]

wrdc.cpp didn't build on OSX due to missing GL/glu.h - I fixed it by copying the version from OpenCPN's sources to src/GL. Didn't we fix this previously?

I think this is fixed for windows but perhaps not for OSX. Did Peter (ptup) create the OSX ? Perhaps he can fix it. Or gerhard (carcode)

When I regard the git there is no glu.h file. Look here: https://github.com/seandepagnier/wea.../master/src/GL
So the compiler is correct claiming about a missing include file.

In June I made two pull requests to Sean, one for this problem and the other to do something semi-smart when the GRIB wind is stronger than what's in a boat's polar model. I think Peter took the changes into his repo but Sean didn't.

[rgleason]

Yes, fogmachine is correct I believe,
however I seem to have
C:\Users\Rick\Documents\GitHub\o-plugin\s-weather_routing_pi\src\GL\
dated 9/8/2015 with gl.h and glext.h also dated 9/8/2015.

Not sure of the process for OSX, but I did a git pull. Does fogmachine want to make sure his git local repos is current?

[rgleason]

PS: Gerhard I went to your link and I found the two files gl.h and glext.h and for some reason it says "14 days ago", however it says "Correct build for wxwidgets 2.8" which was done for Hakan using older MSVC++ I believe. I am still trying to figure out the wonders of git, so maybe I am looking in wrong place? Is something still amiss?

[fogmachine]

I pulled from Sean's repository since it's his plugin. I have it in my own repo, but don't keep it up-to-date with Sean's changes. Just want it to work for other Mac users.

[rgleason]

@fog Yes entirely agree, I am sure Sean will fix it. Thanks for making this clearer. " Just want it to work for other Mac users. "

Weather_routing Manual needs considerably more attention insofar as documentation. I am wondering if we could jointly get this augmented.

I didn't merge them because they contain conflicts that haven't been resolved. I didn't try to resolve them myself because the pull request for the wind speed thing also seems to contain all sorts of other stuff so I don't understand why they aren't separate pull requests.

I believe it should compile now because I added glu.h, but really it's ridiculous that it's needed here at all. If you could try deleting glu.h and see if it can compile now (with latest changes) please let me know so I can remove glu.h again.

Perhaps you want to learn a little bit.
You can read in the file in question (wrdc.cpp) this:

#ifdef __WXMSW__
    #include "GL/gl.h"            // local copy for Windows
    #include <GL/glu.h>
#else

The error of the compiler was: "fatal error: 'GL/glu.h' file not found
#include <GL/glu.h>"
The git has only gl.h and glext.h but no glu.h.
Hope you can understand.

Gerhard

Whoops. Thankyou Gerhard, you are being gentle.

Happy to send just the polar change - it was something like 10 lines of code.

[fogmachine]

Sean, yes wrdc.cpp now compiles w/o src/GL/glu.h on OSX.

Hi Folks,

started using Weather Routing few days ago. Looks I am getting along with it quite ok. There is however one question, I cannot find an answer to. When the routing is done, I see various part circles (blue, green, light green etc.). Can someone please explain what those circles mean?

Many thanks
Klaus

[rgleason]

The circles represent similar times intervals of sailing. Called isochrones. If you set config to 1 hour it is 1 hour sailing between lines.
The blue and green ones are using the grib file and I believe the lighter ones are using climatology. Try turning one of in config and compute again to see what happens.
