Hi there, I’m not quite familiar with hdf5, but my research work requires for building Parallel HDF5, during configuration, error occurs compliant that libmpio.a was not found, and could not find a simple mpi I/o program.  
then I checked my mpich installation, realizing that ROMIO(the mpi I/o implement) was not built correctly, the library in it is empty, I then re-configured mpich with --enable-romio and --enable-mpi-io, but the library libmpio.a was still not generated.  
does romio support gnu make? and can I run Parallel HDF5 on Macos? how to generate libmpio.a library?

this is quite crucial for my research, any help would be really appreciated!
