# This make file will:
#  - Download a set of dependencies and verify the known-good hashes.
#  - Build static libraries of aria2 dependencies.
#  - Create a statically linked, aria2 release.
#    - The build will have all major features enabled, and will use
#      AppleTLS and GMP.
#  - Create a corresponding .tar.bz containing the binaries:
#  - Create a corresponding .pkg installer.
#  - Create a corresponding .dmg image containing said installer.
#
# This Makefile will also run all `make check` targets.
#
# The dependencies currently build are:
#  - zlib (compression, in particular web compression)
#  - c-ares (asynchronous DNS resolver)
#  - expat (XML parser, for metalinks)
#  - gmp (multi-precision arithmetric library, for DHKeyExchange, BitTorrent)
#  - sqlite3 (self-contained SQL database, for Firefox3 cookie reading)
#  - cppunit (unit tests for C++, framework in use by aria2 `make check`)
#
#
# To use this Makefile, do something along the lines of
#  - $ mkdir build-release
#  - $ cd build-release
#  - $ virtualenv .
#  - $ . bin/activate
#  - $ pip install sphinx-build
#  - $ ln -s ../makerelease-os.mk Makefile
#  - $ make
#
# To make an both builds use instead:
#  - $ make multi
#
# If you haven't checkout out a release tag, you need to specify NON_RELEASE.
# $ export NON_RELEASE=1
# to generate a dist with git commit
# $ export NON_RELEASE=force
# to force this script to behave like it was on a tag.
#
# Note: This Makefile expects to be called from a git clone of aria2.
#
# Note: In theory, everything can be build in parallel, however the sub-makes
# will be called with an appropriate -j flag. Building the `deps` target in
# parallel before a general make might be beneficial, as the dependencies
# usually bottle-neck on the configure steps.
#
# Note: Of course, you need to have XCode with the command line tools
# installed for this to work, aka. a working compiler...
#
# Note: We're locally building the dependencies here, static libraries only.
# This is required, because when using brew or MacPorts, which also provide
# dynamic libraries, the linker will pick up the dynamic versions, always,
# with no way to instruct the linker otherwise.
# If you're building aria2 just for yourself and your system, using brewed
# libraries is fine as well.
#
# Note: This Makefile is riddled with mac-isms. It will not work on *nix.
#
# Note: The convoluted way to create separate arch builds and later merge them
# with lipo is because of two things:
#  1) Avoid patching c-ares, which hardcodes some sizes in its headers.
#
# Note: This Makefile uses resources from osx-package when creating the
# *.pkg and *.dmg targets
