There are (at least) 3 methods to install Gum. But first, you must install the following dependencies: python, pygtk, numpy, libsndfile, setuptools, the development files for python, libasound, libsamplerate, libcairo, and gcc. To install these packages on a Debian or Ubuntu box, type:

apt-get install python python-gtk2 python-numpy python-setuptools \
        libsndfile1 python-dev libasound2-dev libcairo2-dev \
        libsamplerate0 libsamplerate0-dev gcc

Install pip (on Debian/Ubuntu: apt-get install python-pip). Then, type in a terminal:

sudo pip install gum-audio
gum

To uninstall Gum:

sudo pip uninstall gum-audio

If you’d rather install Gum in your home directory, you should use pip with virtualenv (apt-get install python-pip python-virtualenv). Type (not as root):

cd $HOME
virtualenv -p python2 --system-site-packages gummy
source gummy/bin/activate
pip install gum-audio
gum

To uninstall Gum, just remove the $HOME/gummy directory.

You’ll need git, cython and make (apt-get install git cython make). Type in a terminal (not as root):

git clone https://github.com/stackp/Gum.git
cd Gum
./build.sh
./run
