Here we demonstrate how to install Dune from source on Ubuntu 20.04 LTS. This is the way to go if you want to have access to all of DUNE’s source files (e.g. because you want to inspect or modify them), to have more control over the build process (e.g. change compiler flags or enable/disable certain libraries) and also get dune-alugrid. Consequently this way of installation is more complex than installation from binary packages. We will simplify life by providing shell scripts that do all the work.

We assume that you are running a freshly installed Ubuntu 20.04 LTS with no additional packages installed yet. In order to install and run Dune you first need to install the following packages (for this to work you need sudo rights):

sudo apt install git
sudo apt install cmake
sudo apt install mpich mpich-doc libmpich-dev
sudo apt install zlib1g zlib1g-dev
sudo apt install paraview
sudo apt install gmsh

In order to automate the installation from source Peter Bastian provides installer scripts. It downloads the following dune modules:

• dune-common
• dune-geometry
• dune-grid
• dune-alugrid
• dune-istl
• dune-localfunctions
• dune-grid-howto
• dune-uggrid

Just check out the following repository

git clone https://conan2.iwr.uni-heidelberg.de/git/peter/dune-installer.git

and run the installer (choose a different folder for other Dune versions or other setups):

./dune-installer/core-2.7.1/installer.sh my-dune-dir

Here my-dune-dir is the name of a new directory where you want your Dune installation in. This will download and install the UG grid manager, download all Dune core modules and create an opts-file and a build-script.

Now you can run the build-script in the newly created directory:

cd my-dune-dir
./buildmodules.sh

If this does not work for you then you need to edit the installer script in dune-installer/core-2.7.1/installer.sh and ask some expert (e.g on the mailing list).

If all went well, where are the compiled files? The build-script sets up things for a so-called ‘out-of-core’ build.

cd release-build

gets you to a directory that mirrors all dune-modules but with the created files in it. In every subdirectory you will find a link src_dir that will lead to the corresponding source directory that created these files.
