Charm installation guide

Before installing Charm, there are a few prerequisites that need to be installed on your system. These are:

Subversion

• sudo apt-get install subversion

m4

• sudo apt-get install m4

Python 3 (this is an optional, though recommended, step)

• sudo apt-get install python3

Header files/static library

• sudo apt-get install python-dev (if you did NOT install Python 3)

• sudo apt-get install python3-setuptools python3-dev (for Python 3.x)

libssl-dev (only necessary if you did not install Python 3)

• sudo apt-get install libssl-dev

GMP

• sudo apt-get install libgmp-dev

Next, we will install Charm. Navigate to your Charm directory.

We must first run the configuration script:

• sudo ./configure.sh

Install PBC from source

• Download source from PBC website: wget https://crypto.stanford.edu/pbc/files/pbc-0.5.14.tar.gz

• tar xzvf pbc-0.5.14.tar.gz

• sudo apt install flex bison

• ./configure LDFLAGS="-lgmp"

• make

• sudo make install

• sudo ldconfig

Now we can build and install Charm:

• sudo make

• sudo make install

• Or you can install via pip: pip install charm-crypto==0.43, without download source code of charm-crypto.

And finally we must rebuild the search path for libraries

• sudo ldconfig

Run Pytests

• sudo make test
