# binaries (and in context it means executables linked with

|
# -static flag, and not just executables linked with static
|
|
# libcrypto.a) is to eliminate dependency on specific run-time,
|
|
# a.k.a. libc version. The mentioned config options are meant
|
|
# to achieve just that. Unfortunately on Linux it's impossible
|
|
# to eliminate the dependency completely for openssl executable
|
|
# because of getaddrinfo and gethostbyname calls, which can
|
|
# invoke dynamically loadable library facility anyway to meet
|
|
# the lookup requests. For this reason on Linux statically

|
# linked openssl executable has rather debugging value than

You have selected the --with-rand-seed=none option, which effectively

disables automatic reseeding of the OpenSSL random generator.

All operations depending on the random generator such as creating keys

will not work unless the random generator is seeded manually by the

application.

Please read the 'Note on random number generation' section in the

=head1 NAME
|
|
|
|
configdata.pm - configuration data for OpenSSL builds
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
Interactive:
|
|
|
|
perl configdata.pm [options]
|
|
|
|
As data bank module:
|
|
|
|
use configdata;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This module can be used in two modes, interactively and as a module containing
|
|
all the data recorded by OpenSSL's Configure script.
|
|
|
|
When used interactively, simply run it as any perl script, with at least one
|
|
option, and you will get the information you ask for. See L</OPTIONS> below.
|
|
|
|
When loaded as a module, you get a few databanks with useful information to
|
|
perform build related tasks. The databanks are:
|
|
|
|
%config Configured things.
|
|
%target The OpenSSL config target with all inheritances
|
|
resolved.
|
|
%disabled The features that are disabled.
|
|
@disablables The list of features that can be disabled.
|
|
%withargs All data given through --with-THING options.
|
|
%unified_info All information that was computed from the build.info
|
|
files.
