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.

2464
2465configdata.pm - configuration data for OpenSSL builds
2466
2467=head1 SYNOPSIS
2468
2469Interactive:
2470
2471 perl configdata.pm [options]
2472
2473As data bank module:
2474
2475 use configdata;
f2d4be3b 2476
b1fafff6
RL		 2477=head1 DESCRIPTION
2478
2479This module can be used in two modes, interactively and as a module containing
2480all the data recorded by OpenSSL's Configure script.
2481
2482When used interactively, simply run it as any perl script, with at least one
2483option, and you will get the information you ask for. See L</OPTIONS> below.
2484
2485When loaded as a module, you get a few databanks with useful information to
2486perform build related tasks. The databanks are:
2487
2488 %config Configured things.
2489 %target The OpenSSL config target with all inheritances
2490 resolved.
2491 %disabled The features that are disabled.
2492 @disablables The list of features that can be disabled.
2493 %withargs All data given through --with-THING options.
2494 %unified_info All information that was computed from the build.info
2495 files.
