h1. Install Xmipp

*TODO:* List the lastest version that we have tested with.

* For more info, see http://xmipp.cnb.csic.es/twiki/bin/view/Xmipp/InstallingTheSoftware

* Go into Xmipp source directory

* Find openmpi directory

<pre>

$ locate libmpi.so

</pre>

<pre>

/usr/lib/openmpi/1.2.7-gcc/lib/libmpi.so

</pre>

* Setup Xmipp to use openmpi by changing three lines in SConstruct

<pre>

$ cp SConstruct SConstruct.orig

</pre>

<pre>

$ nano SConstruct

</pre>

<pre>

opts.Add('MPI_INCLUDE', 'MPI headers dir ', '/usr/lib/openmpi/1.2.7-gcc/include/')

opts.Add('MPI_LIBDIR', 'MPI libraries dir ', '/usr/lib/openmpi/1.2.7-gcc/lib/')

opts.Add('MPI_LIB', 'MPI library', 'mpi')

</pre>

* Compile

<pre>

$ sudo mpi-selector --yes --system --set `rpm --qf '%{NAME}-%{VERSION}-gcc-%{ARCH}\n' -q openmpi`

</pre>

<pre>

$ export PATH=$PATH:/usr/lib/openmpi/1.2.7-gcc/bin

</pre>

<pre>

$ ./scons.configure

</pre>

you should see the line:

<pre>

* Checking for MPI ... yes

</pre>

<pre>

$ ./scons.compile

</pre>
