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

2731
2732configdata.pm - configuration data for OpenSSL builds
2733
2734=head1 SYNOPSIS
2735
2736Interactive:
2737
2738 perl configdata.pm [options]
2739
2740As data bank module:
2741
2742 use configdata;
f2d4be3b 2743
b1fafff6
RL		 2744=head1 DESCRIPTION
2745
2746This module can be used in two modes, interactively and as a module containing
2747all the data recorded by OpenSSL's Configure script.
2748
2749When used interactively, simply run it as any perl script, with at least one
2750option, and you will get the information you ask for. See L</OPTIONS> below.
2751
2752When loaded as a module, you get a few databanks with useful information to
2753perform build related tasks. The databanks are:
2754
2755 %config Configured things.
2756 %target The OpenSSL config target with all inheritances
2757 resolved.
2758 %disabled The features that are disabled.
2759 @disablables The list of features that can be disabled.
2760 %withargs All data given through --with-THING options.
2761 %unified_info All information that was computed from the build.info
2762 files.
