83# libcrypto.a) is to eliminate dependency on specific run-time,
84# a.k.a. libc version. The mentioned config options are meant
85# to achieve just that. Unfortunately on Linux it's impossible
86# to eliminate the dependency completely for openssl executable
87# because of getaddrinfo and gethostbyname calls, which can
88# invoke dynamically loadable library facility anyway to meet
89# the lookup requests. For this reason on Linux statically
90# linked openssl executable has rather debugging value than

2740
2741configdata.pm - configuration data for OpenSSL builds
2742
2743=head1 SYNOPSIS
2744
2745Interactive:
2746
2747 perl configdata.pm [options]
2748
2749As data bank module:
2750
2751 use configdata;
f2d4be3b 2752
b1fafff6
RL		 2753=head1 DESCRIPTION
2754
2755This module can be used in two modes, interactively and as a module containing
2756all the data recorded by OpenSSL's Configure script.
2757
2758When used interactively, simply run it as any perl script, with at least one
2759option, and you will get the information you ask for. See L</OPTIONS> below.
2760
2761When loaded as a module, you get a few databanks with useful information to
2762perform build related tasks. The databanks are:
2763
2764 %config Configured things.
2765 %target The OpenSSL config target with all inheritances
2766 resolved.
2767 %disabled The features that are disabled.
2768 @disablables The list of features that can be disabled.
2769 %withargs All data given through --with-THING options.
2770 %unified_info All information that was computed from the build.info
2771 files.
