If the user specifies an alternative build file than the default, this
alternative is recorded in $config{build_file}, not $target{build_file}.
Therefore, the former should be used, leaving the latter as a mere default.
This is a bug. While fixing it, document it better too.

=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.
|
|
If run with no arguments, it will rebuild the build file (Makefile or
|
|
corresponding).
|
|
With at least one option, it will instead get the information you ask for, or
|
|
re-run the configuration process.
|
|
See L</OPTIONS> below for more information.
|
|
|
|
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.
