###### Basic building (without PETSc or Python)

Most of the necessary dependencies for a basic building are available via modules. We use here `mpi.intel/2018_gcc` for the MPI dependency as an example, since we later load an OpenFOAM module, which needs this MPI version.
We start from a similar setup like the one above:

```bash
module load gcc/7
module load mpi.intel/2018_gcc
module load boost/1.68.0 # Read below if you need yaml-cpp
module load cmake/3.12.1
Currently Loaded Modulefiles:
1) admin/2.0 2) tempdir/1.0 3) lrz/1.0
```

Most of the necessary dependencies for a basic building are available via modules. We use here `mpi.intel/2019.12_gcc` for the MPI dependency as an example, since we later load an OpenFOAM module, which needs this MPI version.

```bash
module load spack/23.1.0
module load gcc/12.2.0
# module load mpi.intel/2019.12_gcc # only needed if -DPRECICE_FEATURE_MPI_COMM=ON
module load boost/1.83.0-gcc12-impi
module load eigen
module load cmake/3.26.3
module load git/2.40.0
```

Before running the command `module load mpi.intel/2018_gcc` the user has to run `module unload mpi.intel` to unload the preloaded mpi version.
Steps for the Eigen dependency are described in the [wiki page for SuperMUC](installation-special-systems.html#supermuc-ng-lenovointel-munich). Afterwards, follow the usual [building instructions for CMake](https://precice.org/installation-source-preparation.html):

make -j 12
make install
```

After installing, make sure you add the preCICE installation paths to your `.bashrc`, so that other programs can find it:

```bash
export PRECICE_ROOT="path/to/precice_install"
export PKG_CONFIG_PATH="path/to/precice_install/lib/pkgconfig:${PKG_CONFIG_PATH}"
export CPLUS_INCLUDE_PATH="path/to/precice_install/include:${CPLUS_INCLUDE_PATH}"
export LD_LIBRARY_PATH="path/to/precice_install/lib:${LD_LIBRARY_PATH}"
