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`.
