The instructions given here install all dependencies of FFGo, except one optional dependency: the [http://geographiclib.sourceforge.net/html/MagneticField.1.html MagneticField] executable from [http://geographiclib.sourceforge.net/ GeographicLib] (see [[FFGo#A word about GeographicLib|below]]). To have a complete installation, that is able to show the magnetic variation at each airport and magnetic headings for runways, routes, etc., you need to do this in addition: | The instructions given here install all dependencies of FFGo, except one optional dependency: the [http://geographiclib.sourceforge.net/html/MagneticField.1.html MagneticField] executable from [http://geographiclib.sourceforge.net/ GeographicLib] (see [[FFGo#A word about GeographicLib|below]]).

# | # Go to [http://geographiclib.sourceforge.net/html/install.html#binaryinst GeographicLib's installation page] and run the appropriate installer for your system. This will install the <tt>MagneticField.exe</tt> executable on your computer. Take note of the folder it is installed to, because you'll have to tell the full path of this program to FFGo, unless you let the GeographicLib installer modify your <tt>PATH</tt> environment variable. | ||
# <tt>MagneticField.exe</tt> needs one or more datasets to be installed, otherwise it can't work properly. To get such a dataset, go to [http://geographiclib.sourceforge.net/html/magnetic.html GeographicLib's page for magnetic models] and install the magnetic model data file(s) of your choice. <tt>wmm2015</tt> should be fine until 2020. You may also install the <tt>emm2015</tt> dataset, however I can't say whether this will bring any visible change for typical aviation usage. | |||
# Otherwise, | # If you let the GeographicLib installer modify your <tt>PATH</tt> in step 1, there is nothing else to do. Otherwise, you have to tell FFGo where to find <tt>MagneticField.exe</tt>. In order to do this, start FFGo and open the ''Settings → Preferences'' dialog; go to the ''Miscellaneous'' tab, and enter the precise path for <tt>MagneticField.exe</tt> in the appropriate field (cf. step 1). Finally, click on ''Save settings'' and you should be done. | ||
The FFGo dialog reachable via ''Help → About'' displays the versions of the main dependencies used by FFGo. In case you entered an invalid path, or some other error, a hint is generally given there. In any case, troubleshooting information is always printed to the terminal (if you ran ''ffgo.exe'' as opposed to ''ffgo-noconsole.exe'') and to the FFGo log file located in the <tt>%APPDATA%\FFGo\config</tt> folder (do a Google search with keywords “Windows” and “APPDATA” if you don't know what this means). | The FFGo dialog reachable via ''Help → About'' displays the versions of the main dependencies used by FFGo.
