Crypt::OpenSSL::Guess − Guess OpenSSL include path
use
ExtUtils::MakeMaker;
use Crypt::OpenSSL::Guess;

−lcrypto'],
INC => openssl_inc_paths(), # guess include path or get
from $ENV{OPENSSL_PREFIX}
);
Crypt::OpenSSL::Guess provides helpers to guess OpenSSL include path on any platforms.
Often macOS’s homebrew OpenSSL cause a problem on installation due to include path is not added. Some CPAN module provides to modify include path with configure-args, but Carton or Module::CPANfile is not supported to pass configure-args to each modules. Crypt::OpenSSL::* modules should use it on your Makefile.PL.
This module resolves the include path by Net::SSLeay’s workaround. Original code is taken from "inc/Module/Install/PRIVATE/Net/SSLeay.pm" by Net::SSLeay.
openssl_inc_paths()
This functions returns include paths in the format passed to CC. If OpenSSL could not find, then empty string is returned.
openssl_inc_paths(); # on macOS: "−I/usr/local/opt/openssl/include"
openssl_lib_paths()
This functions returns library paths in the format passed to CC. If OpenSSL could not find, then empty string is returned.
openssl_lib_paths(); # on macOS: "−L/usr/local/opt/openssl/lib"
find_openssl_prefix([$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")
