'''$FG_ROOT''' | The [[Environment variables|environment variable]] <code>'''$FG_ROOT'''</code> is a '''setting''' referring to the path of the main data directory of [[FlightGear]], which contains the so called ''base package'', also known as [[FGData]]. This setting can also be set from the [[FlightGear Qt launcher]], or the command-line. The base package consists of the default [[aircraft]] and [[scenery]], [[Menubar|GUI]] files, sounds, 3D models etc. | ||
To set <code>'''$FG_ROOT'''</code> from the Qt launcher, click "<code>...</code>" at the top left of the launcher to get the drop down menu and click on <code>Select data files location.</code> | |||
=== | When running FlightGear from a [[command line]], you can set <code>$FG_ROOT</code> via <code>--fg-root=path/to/root</code>. In [[FGRun]], it is set on the paths page, previous to the aircraft selection page. | ||
* '''Mac OS X:''' < | |||
* '''Ubuntu:''' < | As of FlightGear 2.4, it is advised to install additional scenery and aircraft in <code>[[$FG_SCENERY]]</code> and <code>[[$FG_AIRCRAFT]]</code> directories outside <code>$FG_ROOT</code>. This allow for maintaining the additional stuff when installing a new version of FlightGear. | ||
* '''Windows:''' < | |||
== Common paths == | |||
* '''Mac OS X:''' <code>Applications/FlightGear.app/Contents/Resources/data/</code> (right-click on FlightGear.app and select "Show Package Contents" to see the Contents folder) | |||
: <code>$FG_ROOT</code> is not installed automatically. See [[New to FlightGear#Installing on Mac OS X|New to FlightGear]] for an installation manual. | |||
* '''Ubuntu:''' <code>/usr/share/games/flightgear/</code> | |||
* '''Windows:''' <code>Program Files\FlightGear 2020.3\data\</code> (default, '''see note!''') | |||
{{note|Newer '''Windows''' versions are very, very protective about the '''<code>Program Files</code> folder'''. | |||
Installing FlightGear into this folder makes it prone to any problems relating to file read/write permissions. Hence, installing FlightGear into <code>Program Files</code> on Windows Vista and later is not recommended. ''(I have yet to see where installing it outside of the default location actually helps - '''jaxsin''')''}} | |||
== $FG_DATA == | |||
You will sometimes see <code>$FG_ROOT</code> erroneously being mentioned as <code>'''$FG_DATA'''</code>. While there is no <code>$FG_DATA</code> environment variable, the SourceForge repository containing the base package is named <code>[[FGData]]</code> and was earlier named <code>fgdata</code> in Gitorious.<ref>https://www.mail-archive.com/search?q=fgdata&l=flightgear-devel%40lists.sourceforge.net</ref><ref>https://www.mail-archive.com/search?l=flightgear-devel%40lists.sourceforge.net&q=fg_data&x=0&y=0</ref> | |||
