StarPU can be built and installed by the standard means of the GNU
autotools. The following chapter is intended to briefly remind how these tools
can be used to install StarPU.

@node Getting Sources
@subsection Getting Sources

The simplest way to get StarPU sources is to download the latest official
release tarball from @indicateurl{https://gforge.inria.fr/frs/?group_id=1570} ,
or the latest nightly snapshot from
@indicateurl{http://starpu.gforge.inria.fr/testing/} . The following documents
how to get the very latest version from the subversion repository itself, it
should be needed only if you need the very latest changes (i.e. less than a
day!)

The source code is managed by a Subversion server hosted by the
InriaGforge. To get the source code, you need:

@itemize
@item
To install the client side of the software Subversion if it is
not already available on your system. The software can be obtained from
@indicateurl{http://subversion.tigris.org} . If you are running
on Windows, you will probably prefer to use TortoiseSVN from
@indicateurl{http://tortoisesvn.tigris.org/} .

@item
You can check out the project's SVN repository through anonymous
access. This will provide you with a read access to the
repository.

If you need to have write access on the StarPU project, you can also choose to
become a member of the project @code{starpu}.  For this, you first need to get
an account to the gForge server. You can then send a request to join the project
(@indicateurl{https://gforge.inria.fr/project/request.php?group_id=1570}).

@item
More information on how to get a gForge account, to become a member of
a project, or on any other related task can be obtained from the
InriaGforge at @indicateurl{https://gforge.inria.fr/}. The most important
thing is to upload your public SSH key on the gForge server (see the
FAQ at @indicateurl{http://siteadmin.gforge.inria.fr/FAQ.html#Q6} for
instructions).
@end itemize

You can now check out the latest version from the Subversion server:
@itemize
@item
using the anonymous access via svn:
@example
% svn checkout svn://scm.gforge.inria.fr/svn/starpu/trunk
@end example
@item
using the anonymous access via https:
@example
% svn checkout --username anonsvn https://scm.gforge.inria.fr/svn/starpu/trunk
@end example
The password is @code{anonsvn}.
@item
using your gForge account
@example
% svn checkout svn+ssh://<login>@@scm.gforge.inria.fr/svn/starpu/trunk
@end example
@end itemize

The following step requires the availability of @code{autoconf} and
@code{automake} to generate the @code{./configure} script. This is
done by calling @code{./autogen.sh}. The required version for
@code{autoconf} is 2.60 or higher. You will also need @code{makeinfo}.

@example
% ./autogen.sh
@end example

If the autotools are not available on your machine or not recent
enough, you can choose to download the latest nightly tarball, which
is provided with a @code{configure} script.

@example
% wget http://starpu.gforge.inria.fr/testing/starpu-nightly-latest.tar.gz
@end example

@node Optional dependencies
@subsection Optional dependencies

The topology discovery library, @code{hwloc}, is not mandatory to use StarPU
but strongly recommended. It allows to increase performance, and to
perform some topology aware scheduling.

@code{hwloc} is available in major distributions and for most OSes and can be
downloaded from @indicateurl{http://www.open-mpi.org/software/hwloc}.

@node Generating Makefiles and configuration scripts
@subsection Generating Makefiles and configuration scripts

This step is not necessary when using the tarball releases of StarPU.  If you
are using the source code from the svn repository, you first need to generate
the configure scripts and the Makefiles.

@example
% ./autogen.sh
@end example

@example
% ./configure

Details about options that are useful to give to @code{./configure} are given in
@ref{Compilation configuration}.

In order to make sure that StarPU is working properly on the system, it is also
possible to run a test suite.

@example
% make check

In order to install StarPU at the location that was specified during
configuration:

@example
% make install
