install_deps.sh

#!/usr/bin/env sh

#------------------------------------------------------------------------------
# Shell script for installing pre-requisite packages for solidity on a
# variety of Linux and other UNIX-derived platforms.
#
# This is an "infrastucture-as-code" alternative to the manual build
# instructions pages which we previously maintained at:
# http://solidity.readthedocs.io/en/latest/installing-solidity.html
#
# The aim of this script is to simplify things down to the following basic
# flow for all supported operating systems:
#
# - git clone --recursive
# - ./scripts/install_deps.sh
# - cmake && make
#
# TODO - There is no support here yet for cross-builds in any form, only
# native builds.  Expanding the functionality here to cover the mobile,
# wearable and SBC platforms covered by doublethink and EthEmbedded would
# also bring in support for Android, iOS, watchOS, tvOS, Tizen, Sailfish,
# Maemo, MeeGo and Yocto.
#
# The documentation for solidity is hosted at:
#
# http://solidity.readthedocs.io/
