1. Compiling on Debian 8/Ubuntu

1.1. Install dependencies

sudo apt-get update ; sudo apt-get install git gdebi-core;
FILE=`mktemp`.deb; wget "https://github.com/Qfusion/qfusion/raw/master/debian/qfusion-dev_0.4_all.deb" -qO $FILE && sudo gdebi $FILE; rm $FILE

1.2. Clone git repository and generate the Makefile using CMake

git clone https://github.com/Qfusion/qfusion.git
cd qfusion
git submodule update --init --recursive
cd source && cmake .

1.3. Run make

make

Once you have the git repository cloned and setup, you don't need to repeat steps 1.1 and 1.2. To keep your binaries updated, run the following commands (assuming you're in the root directory of the cloned repository):

git pull
git submodule update --recursive
cd source && make

1.4. Cleanup

You may also want to remove gdebi from your system:

sudo apt-get remove gdebi-core
