Hi Stephan: I am glad to help you!
The error message suggests the compiler cannot find the hdf5 libraries. The problem with hdf5 library could be related with some installation issues as well. I think you could try to check that you have installed the following Ubuntu/Debian packages and their dependencies: hdf5-tools h5utils libhdf5-serial libhdf5-serial-dev If this works, then you'll have a complete development platform for meep programming. The following link will help you to understand the code: http://www.glenstark.net/meeppp/docu/index.html Regards, Rafael Gómez Alcalá Asociate Professor Universidad de Extremadura Escuela Politécnica E10003 Cáceres (SPAIN) > Hi Rafael, > great, that worked!
