-====== Installing Python 2.7.3 from source on the Sun Tsessbe Cluster ======
+Page moved to [[howto:compiling_python_2_7_3|Installing Python from source]].
-Before following this guide read through the README file located in the Python Source Install Folder. Also it recommended to make use of temporary or scratch directory to do all the compilation in (i.e. ~/scratch or /tmp/$USER), as to save disk space in your home directory. This guide assumes GCC 4.6.2 has been installed in your home directory as  in [[guide:compiling_gcc|Compiling GCC from Source]]. Ensure that the following lines at the end of your ./bashrc file
-  export LD_LIBRARY_PATH=$HOME/lib:$LD_LIBRARY_PATH
-  export LD_LIBRARY_PATH=$HOME/lib64:$LD_LIBRARY_PATH
-  export PATH=$HOME/bin:$PATH
-  export LDFLAGS="-L$HOME/lib64 -L$HOME/lib"
-  export CPPFLAGS="-I$HOME/include -L$HOME/lib64 -L$HOME/lib"
-  export CXXFLAGS=$CPPFLAGS
-  export F77=gfortran
-log out and in again,
-  $  gcc --version
-  gcc (GCC) 4.6.2
-===== Prerequisites  =====
-Before compiling Python, the zlib library needs to installed.
-  $ cd ~/scratch
-  $ wget http://zlib.net/zlib-1.2.6.tar.gz
-  $ tar -xf zlib-1.2.6.tar.gz
-  $ cd zlib-1.2.6
-  $ make
-Test it!
-  $ make check
-Install if all tests passes
-  $ make install
-===== Download Source =====
-  $ cd ~/scratch
-  $ wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
-  $ tar -xf Python-2.7.3.tgz
-===== Configuration =====
-   $ cd ~/scratch/Python-2.7.3.tgz
-   $ mkdir BUILD
-   $ cd BUILD
-   $ ../configure --prefix=$HOME
-===== Build =====
-   $ make
-If errors occur such as
-  * g++: Internal error: Killed (program cc1plus)
-wait a while and then make again, as the process was killed by the usage limiter which runs on the login node. If nessary try the approach shown in [[guide:compiling_gcc#compiling_gcc|Compiling GCC from Source]].
-===== Check =====
-  $ make test
-No news is good news: If this test command completes with out an error you know that Python has been compiled successfully.
-===== Install =====
-  $ make install
-Add the following to the end of your .bashrc file
-  # Python 2.7.3 installed in home directory
-  PYTHONPATH=~/lib/python:~/lib/python2.7/site-packages/
-Log in and out, then
-  $ python
-  Python 2.7.3 (default, Apr 12 2012, 12:03:56)
-  [GCC 4.6.2] on linux2
-  Type "help", "copyright", "credits" or "license" for more information.
-  >>>
-===== Installing Packages =====
-Before beginning make sure bash environmental variables do not cause a conflict
-  unset CPPFLAGS
-  unset LDFLAGS
-=== iPython ===
-  $ cd ~/scratch
-  $ wget http://archive.ipython.org/release/0.12/ipython-0.12.tar.gz
-  $ tar -xf ipython-0.12.tar.gz
-  $ cd ipython-0.12
-  $ python setup.py install --prefix=$HOME
-provided your $HOME/bin in your PATH variable, ipython should now be available
-=== Nose ===
-  $ cd ~/scratch
-  $ wget http://pypi.python.org/packages/source/n/nose/nose-1.1.2.tar.gz#md5=144f237b615e23f21f6a50b2183aa817
-  $ tar -xf nose-1.1.2.tar.gz
-  $ cd nose-1.1.2
-  $ python setup.py install --prefix=$HOME
-=== Numpy ===
-Before beginning compile the LAPACK and BLAS librariess as in [[guide:compiling_octave|Compiling Octave 3.4.3 from Source]], and copy libraries to $HOME.lib:
-  $lapack-3.4.0> cp lib* $HOME/lib
-Download the last version of numpy source, in your scratch folder. Extract it, run python setup.py install --prefix=$HOME. Then test it (note this requires nose)
-  $ cd ~
-  $ ipython
-  $ import numpy
-  $ numy.test()
-=== matplotlib / pylab ===
-  Download latest version from source forge (version 1.1 in this case)
-  $  cd $MATPLOTLIB_FOLDER
-  $  python setup.py install # --prefix=$HOME is not required as this option used to install python itself
