-====== 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 be 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 pass +
-  $ 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 +
-   $ 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 +
-   +
-If your PATH environmental variable is configured to include $HOME/bin, 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 +
-   +
-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 +
- +
-=== 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. 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  +
-   +
-=== Scipy (minimal install) === +
- +
-This requires that numpy already be installed and that LAPACK library are setup as in the numpy section. Before beginning the scipy installation,​ clear some possibly conflicting bash environmental variables +
-  unset CPPFLAGS LDFLAGS +
-   +
-Then +
-  $ cd ~/scratch +
-  $ wget http://​tenet.dl.sourceforge.net/​project/​scipy/​scipy/​0.10.1/​scipy-0.10.1.tar.gz +
-  $ tar -xf scipy-0.10.1.tar.gz  +
-  $ cd scipy-0.10.1/​ +
-  $ export ATLAS=~/​scratch/​ATLAS/​lib/​Linux_HAMMER64SSE2/​ +
-  $ python setup.py build +
- +
-Once the build has been successfully completed, its time to install and test scipy +
-  $ python setup.py install +
-  $ cd ~ +
-  $ python +
-  $ import scipy +
-  $ scipy.test() +
- +
-which did not work :( +
-  FAILED (KNOWNFAIL=13,​ SKIP=41, failures=2) +
-  Out[2]: <​nose.result.TextTestResult run=5101 errors=0 failures=2>​ +
- +
