72# -static while -static is also a pass-through compiler option (and
73# as such is limited to environments where it's actually
74# meaningful), it triggers a number configuration options,
75# namely no-dso, no-pic, no-shared and no-threads. It is
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.

2563
2564configdata.pm - configuration data for OpenSSL builds
2565
2566=head1 SYNOPSIS
2567
2568Interactive:
2569
2570 perl configdata.pm [options]
2571
2572As data bank module:
2573
2574 use configdata;
f2d4be3b 2575

RL
2576=head1 DESCRIPTION
2577
2578This module can be used in two modes, interactively and as a module containing
2579all the data recorded by OpenSSL's Configure script.
2580
2581When used interactively, simply run it as any perl script, with at least one
2582option, and you will get the information you ask for. See L</OPTIONS> below.
2583
2584When loaded as a module, you get a few databanks with useful information to
2585perform build related tasks. The databanks are:
2586
2587 %config Configured things.
2588 %target The OpenSSL config target with all inheritances
2589 resolved.
2590 %disabled The features that are disabled.
2591 @disablables The list of features that can be disabled.
2592 %withargs All data given through --with-THING options.
2593 %unified_info All information that was computed from the build.info
2594 files.
