= Rebuild mpich2 Debain package =

There are [http://torvalds.cs.mtsu.edu/~zach/debian/current Debian package] provided by Zach Lowry for MPICH2 version 1.0.3. We want to build 1.0.7 package with 1.0.3 package rules. Here is the procedures:

== Extract 1.0.3 debian package rules ==

 * Donwload 1.0.3 debian package source files
{{{
root@r-mpi:~# wget http://www.cs.mtsu.edu/~zach/debian/current/mpich2_1.0.3-2.dsc
root@r-mpi:~# wget http://www.cs.mtsu.edu/~zach/debian/current/mpich2_1.0.3-2.diff.gz
root@r-mpi:~# wget http://www.cs.mtsu.edu/~zach/debian/current/mpich2_1.0.3.orig.tar.gz
}}}
 * We will need '''dpkg-source''' command, so first check if you had installed dpkg-dev
{{{
root@r-mpi:~# apt-get install dpkg-dev
}}}
 * Extract 1.0.3 debian package source
{{{
root@r-mpi:~# dpkg-source -x mpich2_1.0.3-2.dsc
gpg: Signature made Mon 28 Nov 2005 07:49:49 PM PST using DSA key ID 1CE6894E
gpg: Can't check signature: public key not found
dpkg-source: extracting mpich2 in mpich2-1.0.3
dpkg-source: unpacking mpich2_1.0.3.orig.tar.gz
dpkg-source: applying ./mpich2_1.0.3-2.diff.gz
}}}

== Configure 1.0.7 source tar ball ==

 * Download 1.0.7 source tar ball from office website
{{{
root@r-mpi:~# wget http://www.mcs.anl.gov/research/projects/mpich2/downloads/tarballs/mpich2-1.0.7.tar.gz
root@r-mpi:~# tar zxvf mpich2-1.0.7.tar.gz
}}}
 * Copy debian folder from 1.0.3
{{{
root@r-mpi:~# cd mpich2-1.0.7
root@r-mpi:~/mpich2-1.0.7# cp -aRp ../mpich2-1.0.3/debian/ .
}}}
 * We will need '''dch''' command, so first check if you had installed devscripts
{{{
root@r-mpi:~/mpich2-1.0.7# apt-get install devscripts
}}}
 * modified debian/control
{{{
root@r-mpi:~/mpich2-1.0.7# vi debian/control
}}}
