Configuration options</A>
</H2>
<P>
To build MLD2P4 the first step is to use the <code>configure</code> script
in the main directory to generate the necessary makefile(s).
<P>
As a minimal example consider the following:
<PRE>
./configure --with-psblas=/home/user/PSBLAS/psblas-2.3
</PRE>
This assumes that the various MPI compilers and support libraries are
available in the standard directories on the system. Note that the
PSBLAS build directory must be specified with an <EM>absolute</EM> path.
The full set of options may be looked at by issuing the command
<code>./configure --help</code>, which produces:
<PRE>
$ ./configure --help
`configure' configures MLD2P4 1.0 to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or `..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/mld2p4]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-psblas The source directory for PSBLAS, for example,
--with-psblas=/opt/packages/psblas-2.2
--with-libs List additional link flags here. For example,
--with-libs=-lspecial_system_lib or
--with-libs=-L/path/to/libs
--with-clibs additional CLIBS flags to be added: will prepend
to CLIBS
--with-flibs additional FLIBS flags to be added: will prepend
to FLIBS
--with-library-path additional LIBRARYPATH flags to be added: will
prepend to LIBRARYPATH
--with-include-path additional INCLUDEPATH flags to be added: will
prepend to INCLUDEPATH
--with-module-path additional MODULE_PATH flags to be added: will
prepend to MODULE_PATH
--with-umfpack=LIBNAME Specify the library name for UMFPACK library.
Default: "-lumfpack -lamd"
--with-umfpackdir=DIR Specify the directory for UMFPACK library and
includes.
--with-superlu=LIBNAME Specify the library name for SUPERLU library.
Default: "-lslu"
--with-superludir=DIR Specify the directory for SUPERLU library and
includes.
--with-superludist=LIBNAME
Specify the libname for SUPERLUDIST library.
Requires you also specify SuperLU. Default: "-lslud"
--with-superludistdir=DIR
Specify the directory for SUPERLUDIST library and
includes.
Some influential environment variables:
FC Fortran compiler command
FCFLAGS Fortran compiler flags
LDFLAGS linker flags, e.g. -L&lt;lib dir&gt; if you have libraries in a
nonstandard directory &lt;lib dir&gt;
LIBS libraries to pass to the linker, e.g. -l&lt;library&gt;
CC C compiler command
CFLAGS C compiler flags
CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I&lt;include dir&gt; if
you have headers in a nonstandard directory &lt;include dir&gt;
CPP C preprocessor
MPICC MPI C compiler command
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to &lt;bugreport@mld2p4.it&gt;.
</PRE>
Thus, a sample build with libraries in installation
directories specifics to the GNU 4.3 compiler suite might be as
follows, specifying only the UMFPACK external package:
<PRE>
./configure --with-psblas=/home/user/psblas-2.3/ \
--with-libs="-L/usr/local/BLAS/gnu43 -L/usr/local/BLACS/gnu43" \
--with-blacs=-lmpiblacs --with-umfpackdir=/usr/local/UMFPACK/gnu43
</PRE>
Once the configure script has completed execution, it will have
generated the file <code>Make.inc</code> which will then be used by all
Makefiles in the directory tree.
<P>
To build the library the user will now enter
<PRE>
make
</PRE>
followed (optionally) by
<PRE>
make install
</PRE>
