Debian packages

To generate Debian packages, make sure to set the following variables:

cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release ..
make -j $(nproc) package

The directory should now contain a .deb package and the corresponding checksum file. You can install this using your package manager (to be able to remove properly): sudo apt install ./libprecice3.1.2.deb

In case you want to remove this package, use your package manager: sudo apt purge libprecice3.1.2.

Static library

To build preCICE as a static library, you can set -DBUILD_SHARED_LIBS=OFF.

This is not recommended or supported by the preCICE developers! You may contribute here (better support is coming soon).

Disabling native bindings

The library provides native bindings for C and Fortran. They are called native as they are compiled into the resulting library. If you know what you are doing, you can disable them by specifying -DPRECICE_BINDINGS_C=OFF, or -DPRECICE_BINDINGS_FORTRAN=OFF.

We highly discourage you to do this, as the resulting binaries will not be compatible with C or Fortran adapters!

Overriding dependencies

BOOST

Eigen3

  • EIGEN3_INCLUDE_DIR being the root of the repository.

LibXML2

  • LIBXML2_LIBRARIES and LIBXML2_INCLUDE_DIRS

JSON

  • JSON_INCLUDE_DIR this expects the scoped include to work #include <nlohmann/json.hpp

Prettyprint

  • PRETTYPRINT_INCLUDE_DIR this expects the scoped include to work #include <prettyprint/prettyprint.hpp

PETSc

  • Environment variables PETSC_DIR and PETSC_ARCH.

Python

  • PYTHON_LIBRARY, PYTHON_INCLUDE_DIR, NumPy_INCLUDE_DIR (the two latter are often identical)

MPI - Build preCICE using non-default MPI implementation

  • Set CXX to the compiler wrapper if you want to be sure that the right installation is picked.

For using a non-default MPI implementation one can steer the CMake MPI discovery by setting the variable MPI_CXX_COMPILER to the path to the mpicxx compiler wrapper shipped with your MPI distribution of choice.

Example - building with MPICH:

cmake -DPRECICE_FEATURE_MPI_COMMUNICATION=ON -DMPI_CXX_COMPILER=/usr/bin/mpicxx.mpich ..
