[![Build Status](https://travis-ci.org/akiym/Crypt-OpenSSL-Guess.svg?branch=master)](https://travis-ci.org/akiym/Crypt-OpenSSL-Guess) # NAME Crypt::OpenSSL::Guess - Guess OpenSSL include path # SYNOPSIS use ExtUtils::MakeMaker; use Crypt::OpenSSL::Guess; WriteMakefile( # ... LIBS => [openssl_lib_paths() . ' -lssl -lcrypto'], INC => openssl_inc_paths(), # guess include path or get from $ENV{OPENSSL_PREFIX} ); # DESCRIPTION Crypt::OpenSSL::Guess provides helpers to guess OpenSSL include path on any platforms. Often macOS's homebrew OpenSSL cause a problem on installation due to include path is not added. Some CPAN module provides to modify include path with configure-args, but [Carton](https://metacpan.org/pod/Carton) or [Module::CPANfile](https://metacpan.org/pod/Module%3A%3ACPANfile) is not supported to pass configure-args to each modules. Crypt::OpenSSL::\* modules should use it on your [Makefile.PL](https://metacpan.org/pod/Makefile.PL). This module resolves the include path by [Net::SSLeay](https://metacpan.org/pod/Net%3A%3ASSLeay)'s workaround. Original code is taken from `inc/Module/Install/PRIVATE/Net/SSLeay.pm` by [Net::SSLeay](https://metacpan.org/pod/Net%3A%3ASSLeay). # FUNCTIONS - openssl\_inc\_paths() This functions returns include paths in the format passed to CC. If OpenSSL could not find, then empty string is returned. openssl_inc_paths(); # on macOS: "-I/usr/local/opt/openssl/include" - openssl\_lib\_paths() This functions returns library paths in the format passed to CC. If OpenSSL could not find, then empty string is returned. openssl_lib_paths(); # on macOS: "-L/usr/local/opt/openssl/lib" - find\_openssl\_prefix(\[$dir\]) This function returns OpenSSL's prefix. If set `OPENSSL_PREFIX` environment variable, you can overwrite the return value. find_openssl_prefix(); # on macOS: "/usr/local/opt/openssl" - find\_openssl\_exec($prefix) This functions returns OpenSSL's executable path. find_openssl_exec(); # on macOS: "/usr/local/opt/openssl/bin/openssl" - ($major, $minor, $letter) = openssl\_version() This functions returns OpenSSL's version as major, minor, letter. openssl_version(); # ("1.0", "2", "n") # SEE ALSO [Net::SSLeay](https://metacpan.org/pod/Net%3A%3ASSLeay) # LICENSE Copyright (C) Takumi Akiyama.
