<blockquote>Installing the <tt>geographiclib-tools</tt> package is not enough to have the <tt>MagneticField</tt> program working. This program needs one or more datasets which are not part of the <tt>geographiclib-tools</tt> package. One easy way to install the minimal dataset on Debian is to run the following command with root privileges: | |||
<pre>/usr/sbin/geographiclib-get-magnetic minimal</pre> | <pre>/usr/sbin/geographiclib-get-magnetic minimal</pre> | ||
This will automatically download and install a minimal dataset under <tt>/usr/share/GeographicLib/magnetic</tt>, where it can be found by <tt>MagneticField</tt> (not registering the added files with <tt>dpkg</tt> though, which is a bit ugly, cf. [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=687253 Debian bug #687253]). | This will automatically download and install a minimal dataset under <tt>/usr/share/GeographicLib/magnetic</tt>, where it can be found by <tt>MagneticField</tt> (not registering the added files with <tt>dpkg</tt> though, which is a bit ugly, cf.

Otherwise, you can read the [http://geographiclib.sourceforge.net/html/MagneticField.1.html MagneticField(1) manual page] which explains how to tell MagneticField where he should look to find the datasets it needs. | |||
