The command-line installation instructions are presented for Debian Linux systems and derivatives (using apt) and macOS systems (using Homebrew). However, openSUSE and Fedora are known to be working when using their own package managers. Windows installations are not supported yet.
Official packages are available for Ubuntu LTS (currently 20.04) and derivatives and macOS 11, but if your architecture or particular setup necessarily requires compilation from sources, instructions are provided. The build system used is CMake. The library is tested for compilation using gcc (minimum required: 10.2) and clang (minimum required: 11.0). AppleClang currently does not support C++20 Concepts yet and therefore is not usable on macOS at the moment.
Supplied packages are published using the official Launchpad platform for Ubuntu, and a custom Homebrew tap repository for macOS. Packages simply require all the dependencies, namely: MPFR, Cairo, Gnuplot and Python 3.
In order to install the apt package, first you need to import the ppa repository to the ppa list:
sudo add-apt-repository ppa:ariadne-cps/ariadne
Then you can install Ariadne (along with any missing dependencies):
sudo apt-get install ariadne
which will be updated with the latest release as with other apt packages.
In order to install the Homebrew package, you just need to
brew install ariadne-cps/tap/ariadne
which in one line both sets up the “tap” for Ariadne and installs the package along with any missing dependencies. The package will be upgraded with any new versions after a
brew upgrade is issued. The package currently supports x86-64 architectures on macOS Big Sur. Other configurations trigger an automatic build, therefore you should not need to deal with sources any time.
Dependencies for installation from sources
If installed from sources, the only required library dependency is MPFR. To enable the graphical output you will require either Cairo or Gnuplot in order to save into png files. Finally, the Python bindings require the Python headers (version 3 is only supported, since version 2 is discontinued). In particular for Python, there is an internal Git submodule dependency on the header-only pybind11 library. Therefore in order to build the Python interface, Git must be installed even if Ariadne has been downloaded as an archive. Download of the dependency is automatic though.
Finally, if you want to build the documentation, you need Doxygen and a working Latex distribution (including the Math packages).
Please note that adding new dependencies after preparing the build environment requires to re-run the CMake command.
Specific instructions for Ubuntu and macOS follow, starting from installation from pre-compiled packages.
cmake pkg-config git libmpfr-dev libcairo2-dev gnuplot and either
g++-10 for the compiler toolchain.
Additional package required for the Python interface:
Additional packages required for documentation:
cmake git mpfr cairo gnuplot and
gcc@10 if using GCC.
For Cairo support, you may need to set up a permanent variable for the path of pkgconfig by adding the following line in your
To allow building the documentation:
brew install --cask mactex-no-gui and
brew install doxygen.
Downloading the sources
A pre-packaged source zip/tar.gz archive is always available in the releases section of Ariadne’s GitHub space. Still, it is usually preferable to clone the repository using Git, in order to keep the distribution updated as soon as a new release is available. To do that, you shall issue
git clone https://github.com/ariadne-cps/ariadne
which creates an ariadne directory under the present working directory. Let’s switch into that directory.
To build the library from sources in a clean way, it is preferable that you set up a build subdirectory, say:
$ mkdir build && cd build
Then you can prepare the build environment, choosing a Release build for maximum performance:
$ cmake .. -DCMAKE_BUILD_TYPE=Release
At this point, if no error arises, you can build the C++ library and its Python bindings with:
$ cmake --build .
This build does not include the
tests targets. You can build those by supplying targets with the following:
$ cmake --build . --target <TARGET>
or by using the
everything target to include all code targets.
To build the
doc target for documentation, explicitly use:
$ cmake --build . --target doc
then you can access the built documentation from the
docs/html/index.html file in the build directory.
To install the library globally from built sources, you must do
$ cmake --build . --target install
sudo if you require administrator privileges for a Linux installation. Please note that the installation will build the whole distribution beforehand, hence it is preferable that you first build the other targets without administrator privileges, build the install target.
To find the installed library under Ubuntu, you may need to set the LD_LIBRARY_PATH in the .bashrc file of your home directory:
Building executables using Ariadne
The tutorials directory contains two CMake projects that rely on a correct installation of Ariadne, either by using a package or by building the sources. You can copy a project directory in any place on your file system and follow the instructions on the README file inside to check that your installation was successful.
Due to limitations of the C++ standard library on macOS since C++11, you won’t be able to build an executable with GCC if the Ariadne library has been built using Clang, and viceversa. Hence on macOS you shall use the same compiler for both Ariadne and any projects that depend on it. If Ariadne comes from the Homebrew package, then it has been built using g++ 10.
