WeatherFax ...

[seandepagnier]

Also in addition to the HF schedules.. I should like to have an option to retrieve weather fax images from the internet. This could allow automatic update with a single click to populate the list of fax images. Does anyone have a compiled list of urls for these? Maybe this is also possible via email and sailmail as well. Then there is the possibility of the wefax or satellite faxes, but I need to build an antenna.

Here's a link about accessing noaa data by email. Would be a great feature

[seandepagnier]

Ok, I'll look into it. both email and retrieval via urls should be supported.

Anyone get the chance to compile the latest git and play around with the HF schedules?

[rgleason]

on July 30, Sean has made additional commits in github with changes to Weatherfax related to enabling schedules for download of faxes, etc. which we look forward to testing.

See Sean's note about the improvements in this post


I've tried to compile Sean's plugin, however there are output errors. Please see the attached file.

[rgleason]

Sean I hope you get this post. Your commits result in the attached cmake --build . output errors. I hope you can repair them. Let me know so I can recompile with the new features please.

Anybody knows where to find WeatherFaxInternetRetrieval.xml ?
This file is needed in latest Weatherfax_pi version but not in github.

By the way this weatherfax_pi version compiles OK with wxWidgets 2.9.5 and Xcode for Mac OS X. As usual however the wxFormBuilder is buggy with sizers and generates wrong item numbers. The line 17 in WeatherFaxUI.cpp must be: fgSizer8 = new wxFlexGridSizer( 3, 1, 0, 0 );
and not: fgSizer8 = new wxFlexGridSizer( 2, 1, 0, 0 );

Gerhard, I ran into the same message about
WeatherFaxInternetRetrieval.xml This is best used in Linux right now. At the moment it does not compile for Windows, but there are some great features coming for Linux users.

Overview of improvements

File open, edit, delete, close - This is for weatherfax files, png, gif, jpg, tif, etc. Has all the good stuff to manipulate faxes and overlay on Opencpn.

Retrieve > Audio Capture
Failed to set stuff up with dsp, this only works on linux if you have /dev/dsp
--How would we get this setup for Linux?

Retrieve > HF Radio Schedules -Filter Tab - by Boat position or Station with all the freq and information needed. This alone will be helpful!!! All the stations need testing!!! Sean needs help with this.

Retrieve > Internet > URL 1 minute alarm tab and Capture Options Tab (not fully completed yet) - can't get it to retrieve anything because there are no URL's listed yet and we cannot add them. If we could edit and add the proper urls, this would be a big asset when planning and with wifi available.

Retrieve > Internet > Email (not implemented)

All the HF Radio stations need testing!!! Sean needs help with this. Thank you.

[rgleason]

Sean has ugraded Weatherfax significantly for Linux. If you are a Linux user please test. Meanwhile the Windows version still does not seam to compile... I'd very much like to compile this for windows users...any ideas?

How about this solution? Don't know how to implement.

It appears that file georef.c asks for # include "cutil.h"

How do I get cutil.h?

Read Dave's posts in the sticky beta thread.
Plugin Dependencies Problem:

PlugIns must maintain their own local copies of all the files they need to build, independent of the main OCPN source tree. All you really need from the main tree is OCPNPlugIn.h, and it need not be current. It only needs to be current up to the PlugIn API revision supported by the PlugIn in question.

Rick,

I got this plugin to work in 3.3.910 by replacing 'isnan' by '_isnan' where the errors showed.

There were some tinyxml linker errors which went away by copying tinyxml.cpp, tinyxmlerror.cpp and tinyxmlparser.cpp from the main opencpn source into the weatherfax src folder. And then adding them to the Weatherfax project.

Plugin then worked in O 3.3.910, although fitting a sample fax to the chart was difficult.

Bit of a hack but it got the plugin going.

Mike

[rgleason]

Thanks Rasbats, OK To remove MSVC++ compile errors:

A. Isnan errors
Browsing to opencpn-git/plugins/weatherfax_pi/src
With Notepad++ (is this allowed?) opened weatherfaximage.cpp
Went to line 358 if(isnan(minp) || isnan(maxp))
and changed to 358 if(_isnan(minp) || _isnan(maxp))

also line 376 if(_isnan(minp) || _isnan(maxp))

B. Remove Tiny Xml errors.

Copy tinyxml.cpp, tinyxmlerror.cpp, tinyxmlparser.cpp from opencpn/src
to opencpn/plugins/weatherfax_pi/src

Then in opencpn//plugins/weatherfax_pi cmakelist.txt file
edit with notepad++ or similar editor, adding three lines after line 75
src/icons.cpp <-- after this one
src/tinyxml.cpp
src/tinyxmlerror.cpp
src/tinyxmlparser.cpp

It compiled and built but two failed. They were Grib and Weaterfax. Here are the output errors.

It appears that these are for DEBUG errors and do not affect the release plugin. Is that true? How do I fix them, please? Thanks.

Later, nope no DLLS in the plugin/debug or plugin/release, BOTH grib and weatherfax are still failing, as the last output note says.
