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/$USER), as to save disk space in your home directory. This guide assumes GCC 4.6.2 has been installed in your home directory as in Compiling GCC from Source. Ensure that the following lines at the end of your ./bashrc file
export LD_LIBRARY_PATH=$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 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
