Portable version (Windows & Linux)

Install engine and lobby client

First you need to install Mono, 7zip, Wget, and Xprintidle to make the lobby function properly. Find & install them using Software Center, or use the terminal:

sudo apt-get install mono-complete xprintidle p7zip-full wget

Then install the lobby itself. Download from http://zero-k.info/lobby/Zero-K.exe and run Zero-K.exe with Mono runtime, or use the terminal:

wget http://zero-k.info/lobby/Zero-K.exe
mono Zero-K.exe

When Zero-K Lobby starts, it will ask for [YOUR-DATADIR], set it to where you want Zero-K Lobby store & look for stuff (the default is ~/.spring). The lobby will automatically download the engine (currently Spring 98.0.1-451-g0804ae1), Zero-K and the map when you join a battle. The default datadir (~.spring) may be hidden. To show it set hidden folders to visible in your file manager's settings.

If you want to run the latest Spring engine (97+, 98) you need SDL2. Versions of Ubuntu older than 13.10 do not have sdl2 in their default repositories. To install sdl2 in newer versions of Ubuntu:

sudo apt-get install libsdl2-2.0-0

In case you join a room using Spring 98.0.1-451-g0804ae1 and download failed, you can try download it directly and extract it to [YOUR-DATADIR]/engine/98.0.1-451-g0804ae1 :

Spring 98.0 requires libstdc++.so.6, sdl-1.2 and a few other things (use ldd) to run. You can get them by installing Spring package from repository, find & install them using the Software Center, or enter the following in terminal:

sudo apt-add-repository ppa:spring/ppa
sudo apt-get update
sudo apt-get install spring

Optionally, if you want to manually compile spring 98.0.1-451-g0804ae1 yourself, first install its dependencies:

sudo apt-get install build-essential cmake cmake-gui git
sudo apt-get install libglew-dev libsdl-dev libdevil-dev libopenal-dev libogg-dev libvorbis-dev libfreetype6-dev
sudo apt-get install p7zip-full libxcursor-dev libboost-thread-dev libboost-regex-dev
sudo apt-get install libboost-system-dev libboost-program-options-dev libboost-signals-dev

Then download the source files with Git. Navigate into that folder and:

cmake .
sudo make install

You now have Spring 98.0.1-451-g0804ae1 installed. To make Zero-K lobby use your compiled version of spring you need to make two symlinks, one to the unitsync file and one to the spring executable. Do this by running:

ln -s /usr/local/bin/spring [YOUR-DATADIR]/engine/98.0.1-451-g0804ae1
ln -s /usr/local/lib/libunitsync.so [YOUR-DATADIR]/engine/98.0.1-451-g0804ae1

Now Zero-K Lobby will use the engine that you have compiled.

If you're using Linux you might need to download version 98.0.1-451-g0804ae1 from the Help tab.
