Chocolate Doom installation =========================== These are instructions for how to install Chocolate Doom on Unix-like Operating Systems. Dependencies ------------ Chocolate Doom requires the following to be installed: * A C compiler (gcc is recommended) * make (GNU make is recommended) * LibSDL (see http://www.libsdl.org/) * SDL_mixer (see http://www.libsdl.org/projects/SDL_mixer/) * SDL_net (see http://www.libsdl.org/projects/SDL_net/) * Python (optional) Building Chocolate Doom ----------------------- On a Unix system, follow the standard instructions for installing an autotools-based package: 1. Run './configure' to initialise the package. 2. Run 'make' to compile the package. 3. Run 'make install' to install the package. Advanced topics such as cross-compilation are beyond the scope of this document. Please see the GNU autoconf / automake documentation for more information. Installing an IWAD file ----------------------- To play Doom, an IWAD file is needed. This contains the Doom game data. The file usually has one of the following filenames: doom1.wad (Shareware Doom) doom.wad (Registered / Ultimate Doom) doom2.wad (Doom 2) tnt.wad (Final Doom: TNT: Evilution) plutonia.wad (Final Doom: Plutonia Experiment) When you have this file (see the next section, "Obtaining an IWAD file", for how to get this file), install it through one of the following methods: * Put the file into the /usr/share/games/doom or /usr/local/share/games/doom directories. * Install it into a directory and set the environment variable DOOMWADDIR to be the path to that directory. * Install multiple IWADs into separate directories and set the environment variable DOOMWADPATH to be a colon-separated list of directories to search (similar to the Unix PATH environment variable). * Run Chocolate Doom with the '-iwad' command line parameter to specify the IWAD file to use, eg. chocolate-doom -iwad /root/doom2.wad Obtaining an IWAD file ---------------------- Obtaining the IWAD file may be a complicated process under Unix. The method depends on how you obtained your copy of the game: * There have been several CD-based versions of Doom. Generally, the IWAD files can be found on the CD and copied off directly. * The IWAD files may not be directly available on the CD. Look for a program named "deice.exe". In the same directory, there should be a single large file with a numbered extension (eg. "resource.1"); to extract this, follow the same instructions as for the floppy disk version (see below). * If you have the floppy disk version of Doom, first copy the contents of all the floppy disks into a directory together. You will have several large files with numbered extensions. Concatenate these into a single file, eg. cat doom_se.1 doom_se.2 doom_se.3 doom_se.4 doom_se.5 > doom_se.exe The resulting file is self-extracting LHA file. If you have a DOS emulator (such as DOSbox), you can run it to extract the files; alternatively, you can use the Unix LHA tool to extract the archive. * The Doom games are also available for download on Steam (http://www.steampowered.com/). To find the IWAD files, look in your Steam directory, under the "steamapps/common" path. Playing with Chex Quest ----------------------- Chex Quest is a game based on Doom with some minor modifications that was distributed with boxes of Chex cereal in 1997. It is possible to play Chex Quest using Chocolate Doom. To do this, the following files are needed: * The IWAD file 'chex.wad', from the Chex Quest CD. * The dehacked patch 'chex.deh', which can be found in the /idgames repository in utils/exe_edit/patches/chexdeh.zip. Copy these files into a directory together and use the '-iwad' command line parameter to specify the Chex Quest IWAD file: chocolate-doom -iwad chex.wad Installing upgrades ------------------- Chocolate Doom requires a Doom 1.9 IWAD file. Generally, if you install a recent version of Doom you should automatically have a 1.9 IWAD. However, if you are installing from a very old CD version or from floppy disks, you might find you have an older version. The most obvious symptom of an out of date IWAD file is that the game will exit at the title screen before the demo starts, with the message "Demo is from a different game version!". If this happens, your IWAD file is out of date and you need to upgrade. Id Software released upgrade patches that will update your game to 1.9. The following sites have the patches: http://www.doomworld.com/files/patches.shtml http://www.doom2.net/doom2/utils.html ftp://ftp.idsoftware.com/idstuff/doom2 As the patches are binary patches that run as DOS executables, you will need a DOS emulator (such as DOSBox) to install them. Music support ------------- Support for Doom's MIDI music is available through timidity: http://timidity.sourceforge.net/ A good set of patches for Timidity is the eawpats collection, which can be found here: http://www.doomworld.com/idgames/index.php?id=13928 (Doom idgames archive, /sounds/eawpats.zip) If compiling from source, be sure to compile and install timidity before installing SDL_mixer.
