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

2715
2716configdata.pm - configuration data for OpenSSL builds
2717
2718=head1 SYNOPSIS
2719
2720Interactive:
2721
2722 perl configdata.pm [options]
2723
2724As data bank module:
2725
2726 use configdata;
f2d4be3b 2727
b1fafff6
RL		 2728=head1 DESCRIPTION
2729
2730This module can be used in two modes, interactively and as a module containing
2731all the data recorded by OpenSSL's Configure script.
2732
2733When used interactively, simply run it as any perl script, with at least one
2734option, and you will get the information you ask for. See L</OPTIONS> below.
2735
2736When loaded as a module, you get a few databanks with useful information to
2737perform build related tasks. The databanks are:
2738
2739 %config Configured things.
2740 %target The OpenSSL config target with all inheritances
2741 resolved.
2742 %disabled The features that are disabled.
2743 @disablables The list of features that can be disabled.
2744 %withargs All data given through --with-THING options.
2745 %unified_info All information that was computed from the build.info
2746 files.
