Configuring and Building MLD2P4
</H1>
In order to build MLD2P4 it is necessary to set up a Makefile with appropriate
system-dependent variables; this is done by means of the <code>configure</code>
script. The distribution also includes the autoconf and automake
sources employed to generate the script, but usually this is not needed
to build the software.
<P>
MLD2P4 is implemented almost entirely in Fortran&nbsp;2003, with some
interfaces to external libraries in C; the Fortran compiler
must support the Fortran&nbsp;2003 standard plus the extension <code>MOLD=</code>
feature, which enhances the usability of <code>ALLOCATE</code>.
Many compilers do this; in particular, this is
supported by the GNU Fortran compiler, for which we
recommend to use at least version 4.8.
The software defines data types and interfaces for
real and complex data, in both single and double precision.
<P>
Building MLD2P4 requires some base libraries (see Section&nbsp;<A HREF="node6.html#sec:prerequisites">3.1</A>);
interfaces to optional third-party libraries, which extend the functionalities of MLD2P4
(see Section&nbsp;<A HREF="node7.html#sec:third-party">3.2</A>), are also available. Many Linux distributions
(e.g., Ubuntu, Fedora, CentOS) provide precompiled packages for the prerequisite and
optional software. In many cases these packages are split between a runtime part and a
``developer'' part; in order to build MLD2P4 you need both. A description of the base and
optional software used by MLD2P4 is given in the next sections.
