\section{\label{build}Building from sources}
This section describes how to build the \CDI library from the sources on a UNIX system.
\CDI is using the GNU configure and build system to compile the source code.
The only requirement is a working ANSI C compiler.
%First go to the \href{http://www.mpimet.mpg.de/~cdo/download.html}{\tt download} page
%({\tt http://www.mpimet.mpg.de/\~\,cdo/download.html}) to get the latest distribution,
First go to the \href{http://www.mpimet.mpg.de/sw/cdi}{\tt download} page
({\tt http://www.mpimet.mpg.de/sw/cdi}) to get the latest distribution,
if you did not have it already.
To take full advantage of \CDI's features the following additional
library should be installed.
\begin{itemize}
\item Unidata \href{http://www.unidata.ucar.edu/packages/netcdf/index.html}{netCDF} library
({\tt http://www.unidata.ucar.edu/packages/netcdf/index.html})
version 3 or higher.
This is needed to read/write netCDF files with \CDI.
\end{itemize}
%This section is divided into the following sections:
%<ul>
%<li>\ref install_src_unix "Compiling from source on Unix"
%<li>\ref install_bin_unix "Installing the binaries on Unix"
%<li>\ref build_tools "Tools used to develop CDO"
%</ul>
\subsection{Compilation}
Compilation is now done by performing the following steps:
\begin{enumerate}
\item Unpack the archive, unless you already have done that:
\begin{verbatim}
gunzip cdi-$VERSION.tar.gz # uncompress the archive
tar xf cdi-$VERSION.tar # unpack it
cd cdi-$VERSION
\end{verbatim}
\item Run the configure script:
\begin{verbatim}
./configure
\end{verbatim}
Or with netCDF support:
\begin{verbatim}
./configure --with-netcdf=<netCDF root directory>
\end{verbatim}
For an overview of other configuration options use
\begin{verbatim}
./configure --help
\end{verbatim}
\item Compile the program by running make:
\begin{verbatim}
make
\end{verbatim}
\end{enumerate}
The software should compile without problems and the library ({\tt libcdi.a})
should be available in the {\tt src} directory of the distribution.
\subsection{Installation}
After the compilation of the source code do a {\tt make install},
possibly as root if the destination permissions require that.
\begin{verbatim}
make install
\end{verbatim}
The library is installed into the directory {\tt $<$prefix$>$/lib}.
The C and Fortran include files are installed into the directory {\tt $<$prefix$>$/include}.
{\tt $<$prefix$>$} defaults to {\tt /usr/local} but can be changed with
the {\tt --prefix} option of the configure script.
%Alternatively, you can also copy the library from the {\tt src} directory
%manually to some {\tt lib} directory in your search path.
