Recipe for Chocolate Doom
1 Install dependencies
Your Pi will need certain programs to compile Chocolate Doom. Open Terminal from Applications>Accessories>Terminal or connect to the Pi via SSH and install these with the following command: sudo apt-get install libsdl-mixer1.2-dev libsdl-net1.2-dev pythonimaging
Press Y when you are asked to confirm that you wish to proceed with the install.
3 Compile Chocolate Doom
Use the cd command to switch to the newly created directory: cd chocolate-doom-2.2.1
Next, run configure to prepare the necessary files. Now run make to begin compiling them. This can take some time, so feel free to take a break. Once this has completed run the following command to actually install the program: sudo make install
5 Run the Doom setup procedure
Use the following command to launch setup: chocolate-doom-setup -WAD DOOM1.wad
You can use this to configure the display, sound, keyboard layout, mouse and even a gamepad if you have one. Technically, you can use this screen to host and join multiplayer deathmatches as well, but it’s easier just to do this from the command line. See box ( opposite).
2 Download and extract
Go to www.chocolate-doom.org/wiki/index.php/Downloads and use the wget command in the Pi’s Terminal to download it. At the time of writing, for instance, this would be: wget https://www.chocolate-doom.org/downloads/2.2.1/chocolatedoom-2.2.1.tar.gz Once the file has downloaded, extract it using tar – for example: tar xzf chocolate-doom-2.2.1.tar.gz
4 Download WAD file (or files)
Download the shareware version of Doom, using wget . Make sure you are still inside the Chocolate Doom folder and run the following: wget http://www.doomworld.com/3ddownloads/ports/shareware_ doom_WAD.zip
Once the file has downloaded, extract it by running the following: unzip shareware_doom_WAD.zip You’ll see that the resulting file is called DOOM1.WAD.
6 Run Chocolate Doom
To launch Doom run the following: chocolate-doom -WAD DOOM1.WAD Doom will launch in full-screen mode, which can place a strain on the Pi, so consider opening it in a window with this command:
chocolate-doom -WAD DOOM1.WAD -window 640x480 If you have a different WAD file, replace DOOM1.WAD with its name.
