DEFINE[] definitions end up pushed in @{$config{defines}} instead of
being added to the output file list of defines. This allows for the
unusual case where we need something to be defined globally, so it
gets picked up by anything using $(CPPFLAGS).

|
|
# to eliminate the dependency completely for openssl executable

# because of getaddrinfo and gethostbyname calls, which can
|
|
# invoke dynamically loadable library facility anyway to meet

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

All operations depending on the random generator such as creating keys

=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.
