# OS dependencies
sudo apt-get install -y build-essential gfortran
sudo apt-get install -y git curl vim

# Python dependencies
sudo apt-get install -y python-dev python-pip
sudo pip install cython
sudo pip install nose

# Install OpenBLAS
git clone git://github.com/xianyi/OpenBLAS
pushd OpenBLAS
make FC=gfortran
sudo make PREFIX=/usr/local/ install
popd

## If there is no other BLAS library installed on your system,
## OpenBLAS would be used as BLAS library
## If there are any other libraries use the following configuration options

# Numpy
git clone https://github.com/numpy/numpy
pushd numpy
# vim site.cfg  # and put the following content within #### in site.cfg
####
# [default]
# library_dirs = /usr/local/lib
# [atlas]
# atlas_libs = openblas
# library_dirs = /usr/local/lib
# [lapack]
# lapack_libs = openblas
# library_dirs = /usr/local/lib
