78# argued that the only reason to produce statically linked

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

117# it grew impossible to resolve this without sizeable additional

2679
2680configdata.pm - configuration data for OpenSSL builds
2681
2682=head1 SYNOPSIS
2683
2684Interactive:
2685
2686 perl configdata.pm [options]
2687
2688As data bank module:
2689
2690 use configdata;
f2d4be3b 2691
b1fafff6
RL
2692=head1 DESCRIPTION
2693
2694This module can be used in two modes, interactively and as a module containing
2695all the data recorded by OpenSSL's Configure script.
2696
2697When used interactively, simply run it as any perl script, with at least one
2698option, and you will get the information you ask for. See L</OPTIONS> below.
2699
2700When loaded as a module, you get a few databanks with useful information to
2701perform build related tasks. The databanks are:
2702
2703 %config Configured things.
2704 %target The OpenSSL config target with all inheritances
2705 resolved.
2706 %disabled The features that are disabled.
2707 @disablables The list of features that can be disabled.
2708 %withargs All data given through --with-THING options.
2709 %unified_info All information that was computed from the build.info
2710 files.
