Next are downloads for the ‘source’, which includes the source code, the cmake file, and images/assests, and an image package that holds just the image resources used for the game. These are independent downloads. If you want to play the game, you don’t need either of these!
Next is the linux version. This package only contains the game file and the resource files. (NOTE: this is -all- you need to play the game) You will need to install the various SDL packages in order to run this.
If you have a distro that uses apt-get install, you can use the following command:
sudo apt-get install libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev
For those distros that use yum install:
sudo yum install SDL-devel SDL_mixer-devel SDL_image-devel SDL_ttf-devel
