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

2554
2555configdata.pm - configuration data for OpenSSL builds
2556
2557=head1 SYNOPSIS
2558
2559Interactive:
2560
2561 perl configdata.pm [options]
2562
2563As data bank module:
2564
2565 use configdata;
f2d4be3b 2566
b1fafff6
RL		 2567=head1 DESCRIPTION
2568
2569This module can be used in two modes, interactively and as a module containing
2570all the data recorded by OpenSSL's Configure script.
2571
2572When used interactively, simply run it as any perl script, with at least one
2573option, and you will get the information you ask for. See L</OPTIONS> below.
2574
2575When loaded as a module, you get a few databanks with useful information to
2576perform build related tasks. The databanks are:
2577
2578 %config Configured things.
2579 %target The OpenSSL config target with all inheritances
2580 resolved.
2581 %disabled The features that are disabled.
2582 @disablables The list of features that can be disabled.
2583 %withargs All data given through --with-THING options.
2584 %unified_info All information that was computed from the build.info
2585 files.
