Crypt::OpenSSL::Guess - Guess OpenSSL include path
use ExtUtils::MakerMaker; use Crypt::OpenSSL::Guess; WriteMakefile( # ... LIBS => ['-lssl -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.

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"
This function returns OpenSSL's prefix. If set OPENSSL_PREFIX environment variable, you can overwrite the return value.
OPENSSL_PREFIX
find_openssl_prefix(); # on MacOS: "/usr/local/opt/openssl"
This functions returns OpenSSL's executable path.
find_openssl_exec(); # on MacOS: "/usr/local/opt/openssl/bin/openssl"
This functions returns OpenSSL's version as major, minor, letter.
openssl_version(); # ("1.0", "2", "n")
