AIS Radar Plugin missing information

[MerryFisher]

Hi all,

I have a brand new Pi 4, Daisy Hat AIS receiver and a fresh install of OpenPlotter.

When trying to install via opencpn-plugin-aisradar I get the following error:

pi@openplotter:~ $ sudo apt-get install opencpn-plugin-aisradar
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package opencpn-plugin-aisradar
pi@openplotter:~ $

Does anyone have any ideas on how I can get this to work? It works fine on Windows but not on the Pi which is the important one!

Many thanks.

You probably have to build it from source.

Why do you want the AIS radar plugin? The same functionality is built into OpenCPN where it shows all AIS targets.

Thanks transmitterdan.

I know OpenCPN has the system built in but it was more curiosity. I just wanted to see what it would look like and since it is on the site for people to "use" surely it should do that?

[transmitterdan]

I will see if I can build the plugin for Rpi 4 this weekend. The RPi 4 came out late last year and the present OpenCPN version was long before the RPi 4 existed. It cannot use the same libraries as the RPi 3. The RPi is a bit of an experimenter's machine and not everything has been updated to the RPi 4 requirements. It takes time and effort. We are always looking for more help. Coding/support for Linux (many flavors), Windows, RPi 3 and RPi 4 are all created by volunteers.

[MerryFisher]

I totally understand the huge effort required to maintain something like this, it must be a huge feat to get something working again.

I would be very grateful for your efforts if you were able to get things working on the Pi 4.

Come the near future I could be in a position to make a small donation towards the project.

Try downloading this file to your RPi.

https://dl.cloudsmith.io/public/dan-....1-1_armhf.deb

Then at a command line in the folder where the download file is stored type:

sudo dpkg -i aisradar_pi_1.1-1_armhf.deb

This is a manual install so it does not need any PPA setup.

[MerryFisher]

Smooth install and opened without a hitch.

I am just waiting on a new VHF antenna in order to test the data to be piped into it.

I will PM you.

Verezano's AISradar has been configured for Plugin Manager here in github,

the windows version builds and deploys to Cloudsmith and the tarball version can be downloaded and tested (working) with Options>Plugins using "Import Plugin"

However all linux, macos, and mingw builds fail. (Click on the red X and find the errors screens for each build.) Here are the mingw build errors.

Which is typical. I need some help fixing this and would like to learn how to do it.

I have tried fixing a number of things including disabling of json validator and fixing paths, but I am still getting the same error, I need someone who understands how to fix this problem.. all linux, macos and mingw are failing, but windows builds and works fine!

Windows works, others don't

[bdbcat]

Rick...
Surprising that it compiles on Windows...


You need this at the top of Canvas.cpp, and probably all other .cpp files:

#include "wx/wxprec.h"

#ifndef  WX_PRECOMP
  #include "wx/wx.h"
#endif //precompiled headers

Put this code before line 35.

Thanks that helped. Now Windows and MacOS build, but linux is proving picky. Target.cpp:313:46:error 'wxDegtoRad not declared in this scope double angle=wxDegToRad(Brg-Mycog) etc.

https://github.com/rgleason/AISradar...mits/frontend2

Have made sure to put the header you gave on each .cpp file.

/home/circleci/project/src/Target.cpp:192:12: warning: enumeration value ‘ATON_REAL_ONPOSITION’ not handled in switch [-Wswitch] /home/circleci/project/src/Target.cpp:192:12: warning: enumeration value ‘ATON_REAL_OFFPOSITION’ not handled in switch [-Wswitch] /home/circleci/project/src/Target.cpp: In member function ‘bool Target::Render(wxDC&)’: /home/circleci/project/src/Target.cpp:313:46: error: ‘wxDegToRad’ was not declared in this scope double angle=wxDegToRad(Brg-Mycog); ^ /home/circleci/project/src/Target.cpp:319:51: error: ‘wxDegToRad’ was not declared in this scope double ScrCog = wxDegToRad(targetHdt-Mycog); ^

Got some files deploying https://cloudsmith.io/~opencpn/repos...beta/packages/

[rgleason]

This is the code from Target.cpp down at line 313

bool Target::Render( wxDC& dc ) {
bool Result=false;
// Check if the target is less than sqrt 2 times the range away
// This way targets in the corners of the square are still displayed
// Anything furthur away won't display
if (Dist < Range * 1.4) {
// Default to center of view
int x = CanvasCenter.x;
int y = CanvasCenter.y;
if (Dist>(double)0.) {
// Calculate the drawing position using trigonometry
double delta= Dist/Range*(double)Radius;
double angle=wxDegToRad(Brg-Mycog); <----LINE 313 -Error
x += sin(angle) * delta;
y -= cos(angle) * delta;
}
double targetHdt = Cog;
// Calculate the targets direction on the screen
double ScrCog = wxDegToRad(targetHdt-Mycog); <---LINE 319 -Error
DrawShape(dc, x, y, ScrCog);
}
return Result;
}

He has a whole bunch of icons at the beginning of the file. Maybe the includes need to be reiterated below the icons. I think the icons should go in a separate file 'icons.cpp' or something, but I haven't done this before.
https://github.com/rgleason/AISradar...src/Target.cpp


I have copied the include headers down below the icons and will try that.


https://github.com/rgleason/AISradar_pi/tree/frontend2



That is not the problem I guess. There is a suggestion in the error message....

^~~~~~~~~~ /home/circleci/project/src/Target.cpp:330:26: note: suggested alternative: ‘wxDecToHex’ double angle=wxDegToRad(Brg-Mycog);

So I will try that.

[rgleason]

I've changed to 'wxDegToRad' in the two locations in Target.cpp Line 313 & 319 basically,

Now I am getting other errors from that change.

/home/circleci/project/src/Target.cpp:209:12: warning: enumeration value ‘ATON_REAL_OFFPOSITION’ not handled in switch [-Wswitch] /home/circleci/project/src/Target.cpp: In member function ‘bool Target::Render(wxDC&)’: /home/circleci/project/src/Target.cpp:331:36: error: cannot convert ‘wxString’ to ‘double’ in initialization 331 | double angle=wxDecToHex(Brg-Mycog) | ~~~~~~~~~~^~~~~~~~~~~ | | | wxString /home/circleci/project/src/Target.cpp:338:35: error: cannot convert ‘wxString’ to ‘double’ in initialization 338 | double ScrCog = wxDecToHex(targetHdt-Mycog); | ~~~~~~~~~~^~~~~~~~~~~~~~~~~ | | | wxString

https://github.com/rgleason/AISradar_pi/tree/frontend2


And nothing builds, not even windows. So I think that is a dead end and I am stuck.
I am going to change those two changes back.


So I haven't a clue how to get the two lines

• double angle=wxDegToRad(Brg-Mycog); <----LINE 313 -Error
• double ScrCog = wxDegToRad(targetHdt-Mycog); <---LINE 319 -Error

back "in scope"! ... "was not declared in this scope"


I understand now that the images are for the aisradar view, not the toolbar.
