83# libcrypto.a) is to eliminate dependency on specific run-time,

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

2670
2671configdata.pm - configuration data for OpenSSL builds
2672
2673=head1 SYNOPSIS
2674
2675Interactive:
2676
2677 perl configdata.pm [options]
2678
2679As data bank module:
2680
2681 use configdata;
f2d4be3b 2682
b1fafff6
RL		 2683=head1 DESCRIPTION
2684
2685This module can be used in two modes, interactively and as a module containing
2686all the data recorded by OpenSSL's Configure script.
2687
2688When used interactively, simply run it as any perl script, with at least one
2689option, and you will get the information you ask for. See L</OPTIONS> below.
2690
2691When loaded as a module, you get a few databanks with useful information to
2692perform build related tasks. The databanks are:
2693
2694 %config Configured things.
2695 %target The OpenSSL config target with all inheritances
2696 resolved.
2697 %disabled The features that are disabled.
2698 @disablables The list of features that can be disabled.
2699 %withargs All data given through --with-THING options.
2700 %unified_info All information that was computed from the build.info
2701 files.
