CDO Installation (Unix / LINUX)

Requirements for processing CM SAF’s HDF5-files
If you want to use CDO for conversion of CM SAF files, you need to build it with support of some additional libraries (netcdf, hdf, proj, szib, zlib). We recommend to use at least version 1.3.1 of CDO.

On our systems, we have successfully build the package based on the following components:

• cdo-1.3.1.tar.gz
• zlib-1.2.3.tar.gz (needed to build the HDF5-library)
• szip-2.1.tar.gz (needed to build the HDF5-library)
• hdf5-1.6.6.tar.gz (needed to import HDF5 files)
• netcdf-3.6.3.tar.gz (needed to read and write netcdf-files)
• proj-4.6.1.tar.gz (needed to perform spatial operations based on the projection parameters in the metadata of the CM SAF product).

For an example of the installation procedure, see description at the end of this document.

The latest version of cdo is available under https://code.zmaw.de/projects/cdo/files.

Detailed description of installation steps.
Here it is assumed that none of the required components is installed on your system and that you want to do the whole installation in your private directory (i.e. without root privileges on your system). The description refers to an ubuntu/x86 system.

# Required packages:

# cdo-1.3.1.tar.gz

cd ..

# Install zlib:
tar xzf zlib-1.2.3.tar.gz
cd zlib-1.2.3/
./configure --shared --prefix=$INSTALL_DIR
make
make install
cd ..

# Install hdf5 (with zlib and szip support):
tar xzf hdf5-1.6.6.tar.gz
cd hdf5-1.6.6/
./configure --with-zlib=$INSTALL_DIR --with-szlib=$INSTALL_DIR --prefix=$INSTALL_DIR

# Perhaps you need to adapt some of your path-variables:
export LD_LIBRARY_PATH=$INSTALL_DIR/lib
export PATH=$INSTALL_DIR/bin:$PATH
