Hello everyone,  
i just installed OpenFOAM-v2112 / openfoam-adapter and preCICE but I found the following error:

```nohighlight
Everything looks fine in wmake.log.
=== ERROR: Building completed with linking problems: there were undefined symbols. ===
Possible causes:
- Is preCICE discoverable at runtime? Check the content of ADAPTER_PKG_CONFIG_LIBS above.
See wmake.log and ldd.log for more details.

```

i have ubuntu 20.04 and OpenFOAM 2112 with openfoam adapter v1812-v2112 newer  
can you help me please

Looking at your `ldd.log`, these are the undefined symbols:

```nohighlight
undefined symbol: fftw_taint	(/lib/x86_64-linux-gnu/libfftw3_mpi.so.3)
undefined symbol: fftw_join_taint	(/lib/x86_64-linux-gnu/libfftw3_mpi.so.3)

```

This should be related to your system / OpenFOAM installation and looks identical to this topic: [Error while building openfoam-adapter for OpenFOAM-v1912 - #11 by steffenger](https://precice.discourse.group/t/error-while-building-openfoam-adapter-for-openfoam-v1912/794/11)
