Installing (OpenXcom)

Quick Start

OpenXcom requires the original X-COM resources (any version). If you have the Steam version, you can find the game folder in "Steam\steamapps\common\xcom ufo defense\XCOM". Just copy the game subfolders (GEODATA, GEOGRAPH, MAPS, ROUTES, SOUND, TERRAIN, UFOGRAPH, UFOINTRO, UNITS) to OpenXcom's Data folder (usually the "data" subfolder).

Windows

The installer will automatically detect Steam installations and take care of the resource copying for you, just follow the instructions.

If installing manually, copy the resources to the data subfolder.

Mac OS X

Copy the resources to the application’s data resource (right click the application > Show Package Contents > Contents > Resources > data).

Unix-like

OpenXcom requires the following libraries:

• SDL (libsdl1.2)
• SDL_mixer (libsdl-mixer1.2)
• TiMidity++ (timidity)
• SDL_gfx (libsdl-gfx1.2), version 2.0.22 or later
• yaml-cpp, version 0.2.6 or later

Check your distribution’s package manager or the library website on how to install them.

If installing through a package manager, you should copy the resources to /usr/share/openxcom/data, otherwise the data subfolder is preferred.

Data Folder

In most cases the OpenXcom data is in the data subfolder, but it will also look in one of the following paths.

You can also specify your own path by passing the command-line argument "-data ". The X-COM and OpenXcom data can be in different folders.

• <working directory>\data
• <binary directory>\data

Windows

• C:\Documents and Settings\<user>\My Documents\OpenXcom\data
• C:\Users\<user>\Documents\OpenXcom\data

Mac OS X

• <application resources>\data (Mac OS X)
• ~/Library/Application Data/OpenXcom/data (Mac OS X)

Unix-like

• $XDG_DATA_HOME/openxcom/data (Linux)
• $XDG_DATA_DIRS/openxcom/data (Linux)
