Cross-compiling a release

If you are using a different Operating System than the machine you are deploying to, the release you are deploying will not work. But exrm lets us set a different erts directory than the one used by the system. First download the latest version of the erlang/otp distribution for the target platform from this link: https://www.erlang-solutions.com/resources/download.html Let's suppose you downloaded PACKAGE in the directory PATH:

cd <PATH>

Depending on whether you downloaded an rpm or a deb, you now need to uncompress it. For rpms, we can use:

#! /usr/bin/env python

import sys

for line in sys.stdin:
  data = line.strip().split("\t")
  if len(data) != 6:
    continue
  date, time, store, item, cost, payment = data
  print "{0}\t{1}".format(store, cost)

    print "{{0}\t{1}}".format(store, cost)
