Build Soufflé

Pre-Build Packages

Soufflé has pre-built packages for Debian and MAC OS X. You find the pre-built packages here.

Debian Systems

For Debian systems, the HEAD version of Soufflé can be installed from the Launchpad PPA,

Launchpad PPA

You can update your system with unsupported packages from this untrusted PPA by adding ppa:souffle-lang/souffle to your system’s Software Sources using the following instructions:

sudo add-apt-repository ppa:souffle-lang/souffle
sudo apt-get update

Software Requirements

To build and install Souffle, the following software must be installed:

  • Make, Autoconf tools, GNU G++ supporting C++11 and OpenMP (from version 4.8), Bison (from version 3.0.2), Flex, DoxyGen

CLANG++ with OpenMP support can be used as an alternative for G++.

Ubuntu/Debian Build

On a Ubuntu/Debian system, following command installs the necessary developer tools to compile and build Soufflé:

sudo apt-get install autoconf automake bison build-essential clang doxygen flex g++ git make mcpp python

Note that the Ubuntu/Debian version needs to be recent such that G++ 4.8 is part of the standard distribution.

The Soufflé project follows automake/autoconf conventions for configuring, installing and building software. To configure, build, test, and install the project, type:

 cd souffle
 sh ./bootstrap

MAC OS X Build

MAC OS X does not have OpenMP/C++ nor a bison version 3.0.2 or higher installed. We recommend brew to install the required tools to build Soufflé. Run the following commands prior to executing ./configure:

brew update
brew install autoconf automake bison libtool mcpp
brew reinstall gcc --without-multilib
brew link bison --force

Note: Be careful with the search path for bison, so it points to the correct one. By default, macOS includes bison 2.3 at /usr/bin/bison, however brew installs the newer version to /usr/local/bin/bison. This can be done by prepending this directory to the path, however, this can break other systems - PATH=/usr/local/bin:$PATH.

Currently, the souffle-wave preprocessor crashes in macOS, and requires to overwrite the executable in src/ with a symlink to cpp-X. Currently on macOSX, brew installs cpp to /usr/local/Cellar/gcc/6.2.0/bin/cpp-6. This step must occur after make, and will be overwritten each time it is built. In order to run the tests after we overwrite souffle-wave, run make check in the tests/ directory instead of running make check in the the base directory.

In addition, Java JDK is necessary to build the profiler of Soufflé.

Soufflé is built by

cd souffle
export CXX=/usr/local/bin/g++-5
export CXXFLAGS=-fopenmp
export SOUFFLECPP=/usr/local/bin/cpp-5
sh ./bootstrap

Testing Soufflé


 make check

numerous unit tests and regression tests are performed. This may take up to 45min. However, this may be sped up with, for instance:

TESTSUITEFLAGS=-j8 make check

which will run 8 jobs at a time.

Installing Soufflé

If you would like to install Soufflé in your system, specify an installation directory with ./configure --prefix=<install-dir>. The executable, scripts, and header files will be stored in the directory <install-dir>. Use an absolute path for <install-dir>. Type

 make install

to install Soufflé. By setting the path variable


the Soufflé commands souffle and souffle-profile are available to the users.
