NAME

Crypt::OpenSSL::Guess - Guess OpenSSL include path

SYNOPSIS

    use ExtUtils::MakerMaker;
    use Crypt::OpenSSL::Guess;

    WriteMakefile(
        # ...
        LIBS => ['-lssl -lcrypto ' . openssl_lib_paths()],
        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 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.

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 -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")
