In order to build nidium you need at least 5GB of disk space. A build from scratch could takes from 20 to 60 minutes, depending of the speed of your computer.
Typically, on a debian based system you'll require the following dependencies :
$ apt-get install libpci-dev python2.7 git make patch clang pkg-config libgtk2.0-dev libgtk-3-dev mesa-common-dev libglu1-mesa-dev yasm libasound2 libasound2-dev libbz2-1.0
Building nidium on macOS requires Xcode to be installed.
Building nidium on macOS or GNU/Linux :
$ git clone https://github.com/nidium/NidiumTools.git $ git clone --recursive https://github.com/nidium/Nidium.git $ export PYTHONPATH=$(pwd)/NidiumTools/src $ cd Nidium $ ./configure_frontend $ ./bin/nidium
