#!/bin/bash
# Quick hack made to build Ravencoin from git, with depends.
# Made for ubuntu, might work on debian and alike.
# It's best if you understand it, before using it.
# Best used in a docker or similar.
#
# USAGE: ./build-from-git.sh <platform> <branch> <makethreads>
# where platform is one of: windows, osx, linux, arm32v7

# PREF = prefix to WORKPRE. Set this and the rest will be automagic.
# WORKPRE = the directory where everything happens. we cd $WORKDIR before cloning from git.
# GITDIR is the name of the directory we clone into, from git. 
# GITBRANCH is the branch we checkout from git.
# BUILDFOR is the first and only argument to this command, it's linux, windows, arm32v7 or osx.
# THREADS is number of threads we try to use. Some, like openssl, forces -j1. I use distcc. typical should be set to around available cores.
# BASEREF should be set to release for releases, does not matter what else it is when it's not releases.
