I got the follwing error after running make

What version of HDF5 do you have? Those types should be defined by hdf5.h.

[oskooi]

I think the problem here is that you installed the parallel version of HDF5 and are trying to build serial Meep (the default in the configure script) without specifying CC=mpicc CXX=mpic++ when configuring. This is why your compiler is unable to find hdf5.h. This procedure is actually explained in the HDF5 build instructions of the user manual:

Note: If you have a version of HDF5 compiled with MPI parallel I/O support, 
then you need to use the MPI compilers to link to it, even when you are compiling 
the serial version of Meep. Just use ./configure CC=mpicc CXX=mpic++ or whatever 
your MPI compilers are when configuring.

No, this essense of this bug is that this error appears even if meep is built with --without-hdf5, so those functions should not even be compiled.

Please, reopen this bug.

These lines are at the very bottom of this file, and there are no #ifdef HAVE_HDF5 guards in them, which is a bug really.
