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

2739
2740configdata.pm - configuration data for OpenSSL builds
2741
2742=head1 SYNOPSIS
2743
2744Interactive:
2745
2746 perl configdata.pm [options]
2747
2748As data bank module:
2749
2750 use configdata;
f2d4be3b 2751
b1fafff6
RL		 2752=head1 DESCRIPTION
2753
2754This module can be used in two modes, interactively and as a module containing
2755all the data recorded by OpenSSL's Configure script.
2756
2757When used interactively, simply run it as any perl script, with at least one
2758option, and you will get the information you ask for. See L</OPTIONS> below.
2759
2760When loaded as a module, you get a few databanks with useful information to
2761perform build related tasks. The databanks are:
2762
2763 %config Configured things.
2764 %target The OpenSSL config target with all inheritances
2765 resolved.
2766 %disabled The features that are disabled.
2767 @disablables The list of features that can be disabled.
2768 %withargs All data given through --with-THING options.
2769 %unified_info All information that was computed from the build.info
2770 files.
