Raspberry Pi Forums

Hi All,
An update to my previous posts concerning APRS project:

John Hansen (W2FS,Coastal Chipworks) has now released the TNC-Pi , based on his TNC-X design.
I am a happy customer.

However, I still have a software problem:
running xastir v2.0.0 and imagemagick 6.7.7-10 2012-11-24 q16. on a early model B

I have downloaded uk_aprs_maps.zip from Cross Country Wireless website extracted them , ran the inf2geo script & indexed the maps in xastir, but the maps only display as black/tinted garbage.

Can see the maps in all their glory when loaded into imagemagick.
I saw some xastir helpfile references to 'imagemagic support needs to be compiled in' so tried converting the jpeg to xpm (which is an X pixmap?) but they still refuse to display.
Also references to ''maps fail to display' problem have been fixed in version 1.9.x'
years ago I had problems with maps failing under windows because of displaying too few bpp 16/32 .
is this too related to colour depth of the Xserver? and how can I change this easily on the Pi?

And is it too early to ask for an Amateur Radio projects category on the forum?

Further to my attempts to get Xastir displaying raster maps, I decided to compile from source.

A previous verson of xastir (2.0.0) was installed in / sr/bin/ directory: I decided to leave it there.
These notes are written some 12 hours after the event, so I hope my memory (& examination of history)
is accurate enough.

First step was to add to /etc/apt/sources.list, perform apt-get update, cd to /usr/local/src/ then we are ready to begin. This should get you a .tar.gz file which when extracted with gets you a directory of the same name (in this case xastir-2.0.4) with all the relevant files within.
cd to this directory : you will see a scriptfile called 'configure' which is the file we are about to run.
but before this you will need to install some other packages/headers to avoid your pre-compile failing.

I discovered that on my system i needed to do the following before 'configure' would run From what I can work out, Festival provides optional speech output, gpsman optional gps support,
graphicsmagick is for displaying raster maps, libx11-dev and libgraphicsmagick1-dev provides header files,
and lesstif2-dev provides Motif support.

Now we are ready to run our pre-compile script: this then runs our configure script, checking for problems in our environment and generating two files,
summary.log & config.log one of which handily summarises at the end what options are possible e.g. a minimum and maximum
finished install - unfortunately I do not yet know how to choose from these options.
Each time you run this script it appends data to the two logs ( as i found out, fixing each stage in turn!).

With no major problems withe the configure, we can proceed to compilation proper: this appeared to take about 30 minutes or so, and didn't seem to throw up any serious errors so the next step is Finally to get a Desktop shortcut Hopefully this will get you an up-to-date xastir compiled from source.
Unfortunately I still have my problem in that raster maps fail to display.

Managed to get completely hosed, to the point of not booting after an upgrade.
However, did a fresh install of latest raspbian onto new card, installed xastir, and it just works!
Maps display properly, so i'm a happy bunny.

Paulie,

Did you have to install any of the dependencies when you did the new set-up? And did you use a NOOBS install for raspbian or did you compile it up again? I'm having a heck of a time getting the downloaded maps to work.

From what I remember, I downloaded the latest (at that time)version of the Raspbian image,
Then did an apt-get install of Xastir. I didn't need to compile from source.
I think there are some dependencies for graphical display ( Imagemagick or graphicsmagick).
The Image version was before Noobs was released.
From the drop down menus in Xastir, the help/about selection will give you a pop-up dialogue showing version & what was compiled in.


Let me know which online maps you are trying to use & what sort of problem you face.

Paulie,

I'm using the libraries from cloudmade with the .shp and supporting files in them. I have the directory properly set up, and have been installing all the dependencies I can find. I did have the graphicsmagick on there, but am in the process of removing that and installing imagemagick to see if that makes a difference. I have the pcre and shapelib installed as well.

The darned thing works beautifully with the TNC-PI, but the downloaded maps are the one thing I can't to work properly. I've installed everything I can see on http://www.xastir.org/wiki/HowTo:MAPS, with the exception of the lcms, which I can't find.
