Hi Hannes, The build instructions are specific to Ubuntu 16.04 and haven't been tested on 17.10. If you don't have a good reason to build from source, then I would highly recommend using the Conda package. This should get you up and running with just a few commands. Details can be found here <https://meep.readthedocs.io/en/latest/Installation/#conda-packages>.
