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 texlive sudo apt install texlive-science sudo apt install texlive-latex-extra sudo apt install texlive-bibtex-extra sudo apt install texlive-math-extra sudo apt install texlive-fonts-extra sudo apt install paraview sudo apt install gmsh
Note: In fact, all the packages with texlive in the name are not necessary if you do not want to build the documentation on your computer. The Dune grid howto documentation is also available here instead.
In order to create a Dune source installation the following steps are necessary:
- Download all dune modules from Dune’s git server
- Create an appropriate opts-file giving compiler name, compiler options, location of the installed external libraries, etc.
- Run Dune’s build system in all the modules using
In order to automate these steps we provide installer scripts. It downloads the following dune modules:
Just check out the following repository
git clone http://conan2.iwr.uni-heidelberg.de/git/peter/dune-installer.git
and run the installer:
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
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.
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.
