Installing
----------

We strongly recommend that people use the latest official release tarball on
https://www.tarsnap.com/scrypt.html, and build with:

    ./configure
    make
    make install


Platform-specific notes
-----------------------

- On OS X, the version of OpenSSL included with the operating
  system is outdated (0.9.8) and deprecated, and it is recommended
  that scrypt be built with an updated version of OpenSSL.  On OS X
  10.11 "El Capitan" and higher, OpenSSL was removed entirely.  After
  installing a newer version of OpenSSL, use
      CPPFLAGS="-I /path/to/openssl/headers"
      LDFLAGS="-L /path/to/openssl/lib"
  to build scrypt.

  In particular, if you installed OpenSSL using homebrew, you may
  pass the relevant directories directly to ./configure:
      ./configure CPPFLAGS="-I/usr/local/opt/openssl/include" LDFLAGS="-L/usr/local/opt/openssl/lib"

  Alternatively, you may with to add these lines to your $HOME/.profile file:
      export CPPFLAGS="-I/usr/local/opt/openssl/include $CPPFLAGS"
      export LDFLAGS="-L/usr/local/opt/openssl/lib $LDFLAGS"
  and then close & re-open your terminal window.


Building from git
-----------------

For experimental development from git, build with:

    autoreconf -i
    ./configure
    make

- You must have automake 1.11.2 or higher.
- In order to support the `AX_CFLAGS_WARN_ALL` autoconf directive, you will
  need to install the autoconf archive.  On Debian systems, use the
  `autoconf-archive` package; on FreeBSD, use `devel/autoconf-archive`.
