Gravit

Gravit is a free, visually stunning gravity simulator, where you can spend endless time experimenting with various configurations of simulated universes.

Debian/Ubuntu

Prerequisites

Install these packages:

# sudo apt-get install autoconf libsdl1.2-dev libsdl-ttf2.0-dev libsdl-image1.2-dev liblua5.1-0-dev

Unfortunately there is no deb for libagar, so you'll have to build it from source. There are reported build troubles with the latest release (1.4.1), so SVN revision 9102 is recommended:

# svn checkout -r 9102 http://dev.hypertriton.com/agar/trunk agar
# cd agar
# ./configure && make
# sudo make install
# agar-config --version
1.4.2-beta

Building

Gravit uses the autoconf system:

# ./autogen.sh
# ./configure
# make
# sudo make install
