79# argued that the only reason to produce statically linked
80# binaries (and in context it means executables linked with
81# -static flag, and not just executables linked with static
82# libcrypto.a) is to eliminate dependency on specific run-time,
83# a.k.a. libc version. The mentioned config options are meant
84# to achieve just that. Unfortunately on Linux it's impossible
85# to eliminate the dependency completely for openssl executable
86# because of getaddrinfo and gethostbyname calls, which can
87# invoke dynamically loadable library facility anyway to meet
88# the lookup requests. For this reason on Linux statically
89# linked openssl executable has rather debugging value than
90# production quality.

2732
2733configdata.pm - configuration data for OpenSSL builds
2734
2735=head1 SYNOPSIS
2736
2737Interactive:
2738
2739 perl configdata.pm [options]
2740
2741As data bank module:
2742
2743 use configdata;
f2d4be3b 2744
b1fafff6
RL		 2745=head1 DESCRIPTION
2746
2747This module can be used in two modes, interactively and as a module containing
2748all the data recorded by OpenSSL's Configure script.
2749
2750When used interactively, simply run it as any perl script, with at least one
2751option, and you will get the information you ask for. See L</OPTIONS> below.
2752
2753When loaded as a module, you get a few databanks with useful information to
2754perform build related tasks. The databanks are:
2755
2756 %config Configured things.
2757 %target The OpenSSL config target with all inheritances
2758 resolved.
2759 %disabled The features that are disabled.
2760 @disablables The list of features that can be disabled.
2761 %withargs All data given through --with-THING options.
2762 %unified_info All information that was computed from the build.info
2763 files.
