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