Unfortunately I don't have OpenMPI here, I just test on MPICH2. Can I ask you to try the latest beta release before continuing: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.gz There are some changes to the build process: --with-hdf5= is no longer used. Instead set the appropriate CPPFLAGS and LDFLAGS environmental variables. See the new build instructions here: http://www.unidata.ucar.edu/software/netcdf/docs_beta/netcdf-install.html#Quick-Instructions Thanks, Ed Ticket Details =================== Ticket ID: FSF-162192 Department: Support netCDF Priority: Critical Status: Closed
