2 Quick Instructions for Installing NetCDF on Unix

When building netCDF-4, you must first decide whether to support

the use of HDF5 as a storage format.

2.1 Building

NetCDF Without HDF5

If you don't want netCDF-4/HDF5, then build like this:

./configure --prefix=/home/ed/local --disable-netcdf-4

make check install

(Replace “/home/ed/local” with the name of the directory where

netCDF is to be installed.)

If you get the message that netCDF installed correctly, then you

are done!

2.2 Building

NetCDF With HDF5

If you want to use the HDF5 storage format, you must have the HDF5

1.8.6 release. You must also have the zlib compression library,

version 1.2.5. Both of these packages are available from the

netCDF-4 ftp site atftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4.

Make sure you run “make check” for the HDF5 and zlib distributions.

They are very well-behaved distributions, but sometimes the build

doesn't work (perhaps because of something subtly misconfigured on

the target machine). If one of these libraries is not working,

netCDF will have serious problems.

Optionally, you can also build netCDF-4 with the szip 2.0 library

(a.k.a. szlib). NetCDF cannot create szipped data files, but can

read HDF5 data files that have used szip.

If you wish to use szip, get it from the HDF5 download

page:http://hdfgroup.org/HDF5//HDF5/release/beta/obtain518.html.

If “make check” fails for either zlib or HDF5, the problem must be

resolved before the netCDF-4 installation can continue. For HDF5

problems, send email to the HDF5 help desk: help@hdfgroup.org.

Build zlib like this:

./configure --prefix=/home/ed/local

make check install

Then you build HDF5, specifying the location of the zlib

library:

./configure --with-zlib=/home/ed/local --prefix=/home/ed/local

make check install

Note that for shared libraries, you may need to add the install

directory to the LD_LIBRARY_PATH environment variable. See the FAQ

for more details on using shared libraries:http://www.unidata.ucar.edu/netcdf/faq.html.

If you are building HDF5 with szip, then include the –with-szlib=

option, with the directory holding the szip library.

After HDF5 is done, build netcdf, specifying the location of the

HDF5, zlib, and (if built into HDF5) the szip header files and

libraries in the CPPFLAGS and LDFLAGS environment variables.

CPPFLAGS=-I/home/ed/local/include LDFLAGS=-L/home/ed/local/lib ./configure --prefix=/home/ed/local

make check install

Howdy Stephen!

The --with-hdf5 option has been removed from 4.1.3 (the current

release)

and will not be in any future releases.

It might seem more robust, but it is not. It fails badly in the

area of

32/64 bit platforms (i.e. platforms that want both a 32 bit and a

64 bit

version of the library installed at the same time.) It also adds a

lot

of code to our build system.

The correct way to solve this is with the environment variables,

which

leaves full control in the hands of the hands of the user.

The use of the --with options was an plot perpetrated by my evil

twin,

who hates netCDF and all it stands for. He roams the Earth,

attempting

to convince scientists to store their data in undocumented

binary

formats. It makes for an awkward Thanksgiving dinner, but that's

family

for you.

Thanks,
