Question: I downloaded the version of Dwarf Fortress for Linux onto my computer, but when I click on the `df` file, it doesn't do anything. When I run it in a terminal, it gives me this message: 

```
error while loading shared libraries: libSDL_ttf-2.0.so.0: cannot open shared object file: No such file or directory

```

Answer: 
The Dwarf Fortress archive you downloaded features no dependency resolution, and that error indicates you haven't installed the necessary libraries to play.

Open a terminal and enter the following:

```
sudo apt-get install libsdl1.2debian libsdl-image1.2 libsdl-ttf2.0-0

```

That should allow Dwarf Fortress to run correctly unless you are on a 64-bit installation. On 64-bit installations, you may need to add ":i386" as seen here:

```
sudo apt-get install libsdl-image1.2:i386 libsdl-ttf2.0-0:i386 libgtk2.0-0:i386 libjpeg62:i386 libglu1-mesa:i386 libopenal1:i386

```

You may also run into problems with sound. If so, you can follow the directions on the dwarf fortress wiki, which suggest the following:

```
$ cd df_linux/libs
$ ln -s /usr/lib/i386-linux-gnu/libopenal.so.1 ./libopenal.so
$ ln -s /usr/lib/i386-linux-gnu/libsndfile.so.1 ./libsndfile.so

```
I was having the same issue and found a very easy workaround. Install Wine using software center and download the windows version of Dwarf Fortress.

After Dwarf Fortress is downloaded and wine is installed, go in dwarf fortress folder and right click Dwarf Fortress.exe and select Open With and then wine program loader. It just works. I thought it was easier than playing around with the libraries.
