#! /bin/bash

## run this script as su to install three numerical python packages: numpy, scipy and mathplotlib. They must be installed in sequence. Must be issued as SU.

### Lapack and Blas and ATLAS are assumed to have been installed in existing Linux. 

### WARNING: IF LAPACK, ATLAS, BLAS ARE COMPILED USING GNU, THEN THE NUMPY PACKAGES MUST ALSO BE COMPILED WITH GNU ALSO. IF LAPACK/BLAS/ATLAS ARE COMPILED USING GFORTRAN, THEN THE NUMPY PACKAGES MUST ALSO BE COMPILED WITH GFORTRAN. IF BOTH ARE COMPILED USING DIFFERENT COMPILER, SUGGEST TO UNINSTALL BLAS/LAPACK/ATLAS, AND REISNTALL THEM USING THE GNU COMPILER. (hope that you never need to do that)

# By default, the numpy are to be compiled using gnu whenever possible.

# 1) intalling numpy:
wget http://www2.fizik.usm.my/configrepo/howto/numpy/numpy-1.4.1.tar.gz
tar -zxvf numpy-1.4.1.tar.gz
cd numpy-1.4.1
python setup.py build --fcompiler=gnu
python setup.py install 

# 2) installing scipy
wget http://www2.fizik.usm.my/configrepo/howto/numpy/scipy-0.7.2.tar.gz
tar -zxvf scipy-0.7.2.tar.gz
cd scipy-0.7.2
python setup.py config_fc --fcompiler=gnu install

# To Test if scipy works, run the following script manually.
# cd /root/configrepo
# python 
# >>> import scipy
# >>> scipy.test('full')

#3) For matplotlib-0.99.1.1
wget http://www2.fizik.usm.my/configrepo/howto/numpy/matplotlib-0.99.1.2.tar.gz
tar -zxvf 
cd matplotlib-0.99.1.1
python setup.py build
python setup.py install
