Step 1: Download

You can obtain the latest release of Schnek on the GitHub repository, here. This should be relatively bug-free. If you want to use Schnek for your own projects then this is your choice.

If you are interested in contributing and helping to improve Schnek, you are very welcome to do so. In this case you can grab the latest development version using git. The command is

git clone

You now have downloaded the master branch into a new directory called Schnek. If you want to fix a bug in the li
git checkout -b develop origin/develop
The second command above switches to the develop branch. This branch should be used as the basis when adding new features to the library.

Step 2: Configuration

The configuration and installation script have been generated using the GNU automake utility. For the typical configuration simply type


in the directory that you unpacked Schnek into. This will run the configure script and create make files for the next step of the installation process.

For more control over the configuration you can pass options to configure. If you want to install Schnek into a directory different from the standard installation directory, use the --prefix option, like this

./configure --prefix=/your/installation/directory/

Schnek can be compiled with or without MPI support. By default Schnek will be compiled with MPI support if MPI can be found. You can force MPI to be enabled or disabled using the --with-mpi option. The following command will disable MPI even on those systems where it is present.

./configure --with-mpi=no

If MPI is enabled, Schnek will be compiled using the mpic++ compiler command. If you want to control mpic++ you should set your environment variables according to the documentaion of your MPI version.

You can switch HDF5 support on or off using the --with-hdf5 option. You can specify yes or no to enable or disable HDF5. By default, HDF5 support is enabled. If your HDF5 headers are located in a non-standard location you can also specify the path to your HDF5 installation.

./configure --with-hdf5=/path/to/hdf5/

A full list of available options written out with the --help option.

./configure --help

Step 3: Building the library

Once you have configured Schnek, type


to build the library.

Step 4: Installing

Finally, install the library by typing

make install


sudo make install

depending on the installation directory.

Step 5: Include Schnek in your projects

By default the Schnek headers are located in /usr/local/include/schnek/. To include the headers in your C++ files, you should include them like this.

#include <schnek/grid.hpp>

You nee to link your code to the Schnek libraries. For most compilers this should be achieved by adding -lschnek to your linker flags.
