building oc from source with high res base map for dummies

[Andreas29]

Hi,

maybe I´didn´t use the riht searching terms and maybe I´m too stupid to understand the how-to right.

When building oc from source for a raspberry pi jessie system how can I get the high-res base world map?

Is there a step by step solution for dummies?

Thanks

Andreas

Andreas...
Could you be a little specific where exactly in https://opencpn.org/wiki/dokuwiki/do...ized_packaging you got lost so I can improve the instructions?

Thanks

Hi,

@nohal: Pavel, thanks for giving me a helping hand .

I understand this guide https://opencpn.org/wiki/dokuwiki/do...ing_linux:rpi2

I found the description from your link also.

I think (but I don´t know) that I have to put the ...tar.xz-file in the same directory where the other source code from the git clone command was saved?

Sorry for beeing such a noop but compiling was not my world since yet

And when I try to walk this way I can try to fix the problem with the wind barbs in the grib plugin. You wrote in the corresponding post "If you build from source, the fix is simple - after the code highlighted in the github link above, set m_pixelMM to "Your screen width in millimetres/your screen horizontal resolution" "
So in the griboverlayfactory.cpp file I have to do the changes. Ok. When looking at the lines 240 to 250 I can found the if..else..endif command with the m_pixelMM-definition. Do I have to change all this m_pixelMM-commands or ignore this and still put a command in a inserted line after the if..else..endif command? How is then the Syntax?
Just m_pixelMM=x.xx (with x.xx = the result of the division you wrote)?

Thanks for your private lessons

Regards

Andreas

The additional GSHHS data files belong to https://github.com/OpenCPN/OpenCPN/t...ter/data/gshhs where the crude resolution files already are.

On the, now empty, line 251, you write

m_pixelMM=x.xx;

Where x.xx is (<your screen width in mm>/<your screen width in pixels>), a number much smaller than 1. Given you use the current master branch code and did not modify anything in that file.

Hi,

@nohal: Pavel thanks for your patience. I think that the theme with the changes in the code is clear for me.

But the building-theme sadly not.
In the wiki link you wrote in your first post stand:"Note: Just the crude GSHHS data are now contained in the code repository, to use the higher levels, get the whole dataset from opencpn-gshhs_2.2.4.orig.tar.xz (87mb) "

So when I want to built a version with the "full" base map I have to download the 87mb ...tar.xz-file and put it in my local "built" folder an than run the cmake command with the corresponding parameters?

No.
You have to download the 87MB file and extract it to your local (already existing and containing 3 files) "<wherever your OpenCPN source is>/data/gshhs/" folder. Then

cd <wherever your OpenCPN source is>/build/
cmake -DBUNDLE_DOCS=ON -DBUNDLE_TCDATA=ON -DBUNDLE_GSHHS=FULL ..
make
sudo make install

Hi,

@nohal: Pavel, thanks for giving me a guiding hand to help me out of the maze

Kind regards

Pavel & Andreas, I'll try to make this clearer in the manual.

just to be correct: the file is 68,9 Mb

Hi,

Hi,

@nohal: @rgleason:

Sorry I can´t produce a Version with the full base map

I followed this guide: https://opencpn.org/wiki/dokuwiki/do...ing_linux:rpi2

When I run the "cmake -DBUNDLE_DOCS=ON -DBUNDLE_TCDATA=ON -DBUNDLE_GSHHS=FULL .." command and then "make" and
"sudo make install" I got an error message (see attachment).
When I run the same with "DBUNDLE_GSHHS=CRUDE" all works but with the crude Basic map.
Try to edit the cmake file and delete the lines with the files who are not present. No errors but only crude map

The windbarbs are now ok but the isobars are like the (large) windbarbs. What line do I have to change to solve this (like the windbarbs)?

What is my fault? Why I didn´t get the -l- and -i- files (the poly, the borders and rivers are missing)?

Thanks and regards

Andreas

[nohal]

Andreas...
Nothing is attached. What exactly is the error message you see?
What exactly is the content of the data/gshhs/ folder in your opencpn source tree?

Pavel

[Andreas29]

Hi,

@nohal: Pavel I´m sorry. I forgot to load up the attachment, was too fast when I posted the last threat.

So I send it know.

All the files type -l- and -i- are not present in this directory when run the "cmake -DBUNDLE_DOCS=ON -DBUNDLE_TCDATA=ON -DBUNDLE_GSHHS=FULL .." command.

Regards

Andreas

Andreas...
This is the content of the directory, now, after I have placed there the files from the archive I downloaded 3 minutes ago...

I am honestly out of ideas how is it possible it is not there on your system.

And, what is there on your system?
