To compile from sources you'll need:
a C/C++ compiler (gcc for most of targets, on Win32 visual C++ may work).
Cmake 2.6 or better.
SDL2 library for developpers.
The Zlib library for developpers.
A subversion (SVN) client.
Detailed procedure for linux ubuntu 12.04 and above:
(tested with ubuntu 12.04 amd64 freshly installed from iso image with virtualbox)
Open a terminal window:
_ install C++ compiler, cmake, subversion and library
sudo apt-get install g++
sudo apt-get install cmake
sudo apt-get install subversion
sudo apt-get install zlib1g-dev
sudo apt-get install libpng-dev
(please note that on a new ubuntu installed machine, apt-get may be locked until all other package managers are running... wait a bit...)
create a build dir
For ubuntu 14.04 and above (SDL2 is already a package):
sudo apt-get install libsdl2-dev
Otherwise (need to compile SDL2 from sources):
SDL2 version 2.0.4 is not part of ubuntu until 14.04, you need to compile from sources and at least with video support.
tar xzf SDL2-2.0.4.tar.gz
Install some sdl dependencies (this is a single line):
sudo apt-get install libudev-dev libts-dev libgl1-mesa-dev libglu1-mesa-dev libasound2-dev libpulse-dev libopenal-dev libaudiofile-dev libdbus-1-dev libdirectfb-dev
At the end of configure check that audio and video driver are present
audio : one or many from (oss,alsa,pulse)
video : x11 opengl
sudo make install
SDL2 2.0.4 is now installed on your system
get latest source code from sourceforge (branch branch_realtime) (this is a single line):
svn checkout svn://svn.code.sf.net/p/previous/code/branches/branch_realtime previous-code
Run the program
