-====== Installing Python 2.7.3 from source on the Sun Tsessbe Cluster ====== +
- +
-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 +
- +
