Hello, I installed precice@2.2.0 compiled with gcc@11.4.0 using spack. I am using Ubuntu 22.04.3 LTS (Jammy Jellyfish). When building the CalculiX adapter, I keep getting the error “fatal error: precice/SolverInterfaceC.h: No such file or directory” despite linking the make command to the directory with the file libprecice.pc and cleaning the make. I read the hint in troubleshooting for linking precice, suggesting that the structure of the directories could be the reason. However, mine should be right, as the header files are located in /include/precice/ Dummy solvers are running fine. So that makes me think that my preCICE installation should be right.

Which state of the CalculiX adapter are you trying to build? We have a new page in the documentation on finding the preCICE installation: [Building from source - Finding | preCICE - The Coupling Library](https://precice.org/installation-source-finding.html) Try manually setting the `CPATH`, as a workaround. ---

Hello, Thank you for the reply. It works now! By following the instructions to set `PRECICE_PREFIX` from the documentation, I do not get any errors anymore. I am using the adapter of CalculiX for preCICE 2.2.0. Basically, the one from the link in the documentation ([https://github.com/precice/calculix-adapter/archive/refs/heads/master.tar.gz](https://github.com/precice/calculix-adapter/archive/refs/heads/master.tar.gz)).
