It depends on whether you are downloading the pre-built binary HDF5 library or downloading the source to build and install yourself. For the pre-built binaries, you can install HDF5 in the same directories as netCDF. For example, if netCDF is installed in /usr/local (in the subdirectories lib, include, bin, and share of /usr/local), then HDF5 binaries can be installed in the same directories. If you're building from source, don't download the HDF5 sources into the same directory as the netCDF sources! But you can make sure they're installed in the same directories by specifying the same parent directory with the --prefix option to the configure script, for example --prefix=/usr/local . If you build with CMake instead of configure, you can do the analogous thing by specifying the same install parent directory. We recommend just building from the sources as a normal user (not as root), but then running "make install" as root or with "sudo make install", to get things installed where they belong. --Russ > i’m working on a server and one concern other people have is that if i > install any updates it will stop their models from working. thus i’m trying > to keep all my stuff contained > > cheers and thanks for the support > > Ben > > On Sep 9, 2014, at 2:14 PM, Unidata netCDF Support <address@hidden> wrote: > > > Ben, > > > >> thanks for getting back to me last week. > >> Can you tell me where I can get the updated version of HDF5? > >> > >> i’ve looked on your website and can’t seem to find that. > > > > We've got a source release here: > > > > ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4/hdf5-1.8.13.tar.gz > > > > but a better place would be the The HDF Group site where we got it > > from: > > > > http://www.hdfgroup.org/HDF5/release/obtain5.html > > > > If you don't see a pre-built binary distribution for your platform, > > get the source code release under the "All Platforms" link. > > > > --Russ > > > >> Ben > >> > >> > >> On Sep 5, 2014, at 12:17 PM, Unidata netCDF Support <address@hidden> wrote: > >> > >>> Hi Ben, > >>> > >>> You have to use a more recent version of HDF5, 1.8.8 or later, with netCDF > >>> 4.3. > >>> ?2? > >>> . > >>> > >>> There was a bug in HDF5-1.8.7 > >>> ?that the > >>> current netCDF version > >>> ? detects > >>> when built with > >>> ?that version (or earlier) of HDF5. > >>> > >>> ?Your "make check" should work > >>> fine with HDF5 versions 1.8.8 and later.
