#! /bin/bash

# This script installs mylammps automatically. Proven to work at least for fedora 13.

## Before running this script, make sure that the following numerical packages fftw2-devel.x86_64 fftw2.x86_64 fftw-static.x86_64 fftw-devel.x86_64 mpich2.x86_64 mpich2-devel.x86_64 libblas liblapack have been installed. The best option is to first download and execute the file http://www2.fizik.usm.my/configrepo/howto/inst_numeric before running this script.
 
# This script will create a folder mylamps in ~/ (home directory of current user).
# Choose either scp from www2 (not current version) or git (current/latest version) or wget. By default, wget is used.
# Make sure you have git installed, or yum install git.x86_64 as root, if you wish to download with git clone (instead of scp)

# Use either Option 1 or Option 2, but not both to download the mylammps. By default, Option 2 is used. Option 2 is faster but it does not contains the lastest version of mylammps. Option 1 is slower but it downloads directly the latest version from the source in the web.

## Option 1. Uncomment if want to use this option.
# git clone http://git.icms.temple.edu/lammps-ro.git mylammps 
## End of Option 1

## Option 2. Default option.
