# Build the VERY BASIC reproduction pipeline dependencies before everything
# else using minimum Make and Shell.
#
# ------------------------------------------------------------------------
# !!!!! IMPORTANT NOTES !!!!!
#
# This Makefile will be run by the initial `./configure' script. It is not
# included into the reproduction pipe after that.
#
# This Makefile builds very low-level and basic tools like GNU Tar, and
# various compression programs, GNU Bash, and GNU Make. Therefore this is
# the only Makefile in the reproduction pipeline where you MUST NOT assume
# that modern GNU Bash or GNU Make are used. After this Makefile, other
# Makefiles can safely assume the fixed version of all these software.
#
# This Makefile is a very simplified version of `dependencies.mk' in the
# same directory. See there for more comments.

# Tarballs
# --------
#
# Prepare tarballs. Difference with that in `dependencies.mk': `.ONESHELL'
# is not recognized by some versions of Make (even older GNU Makes). So
# we'll have to make sure the recipe doesn't break into multiple shell
# calls (so we can preserve the variables).
#
# Software hosted at akhlaghi.org/src: As of our latest check (November
# 2018) their major release tarballs either crash or don't build on some
# systems (for example Make or Gzip), or they don't exist (for example
# Bzip2).
#
# In the first case, we used their Git repo and bootstrapped them (just
# like Gnuastro) and built the most recent tarball off of that. In the case
# of Bzip2: its webpage has expired and doesn't host the data any more. It
# is available on the link below (archive.org):
#
# https://web.archive.org/web/20180624184806/http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz
#
# However, downloading from this link is slow (because its just a link). So
# its easier to just keep a with the others.
