77 # used for the space character in order to avoid having to quote
78 # the option. For example, -opt%20arg gets expanded to -opt arg.

81 # -static while -static is also a pass-through compiler option (and
82 # as such is limited to environments where it's actually
83 # meaningful), it triggers a number configuration options,
84 # namely no-pic, no-shared and no-threads. It is
85 # argued that the only reason to produce statically linked
86 # binaries (and in context it means executables linked with
87 # -static flag, and not just executables linked with static
88 # libcrypto.a) is to eliminate dependency on specific run-time,
89 # a.k.a. libc version. The mentioned config options are meant
90 # to achieve just that. Unfortunately on Linux it's impossible
91 # to eliminate the dependency completely for openssl executable
92 # because of getaddrinfo and gethostbyname calls, which can
93 # invoke dynamically loadable library facility anyway to meet
94 # the lookup requests. For this reason on Linux statically
95 # linked openssl executable has rather debugging value than

2721 As data bank module:
2727 This module can be used in two modes, interactively and as a module containing
2728 all the data recorded by OpenSSL's Configure script.
2730 When used interactively, simply run it as any perl script, with at least one
2731 option, and you will get the information you ask for. See L</OPTIONS> below.
2733 When loaded as a module, you get a few databanks with useful information to
2734 perform build related tasks. The databanks are:
2736 %config Configured things.
2737 %target The OpenSSL config target with all inheritances
2739 %disabled The features that are disabled.
2740 @disablables The list of features that can be disabled.
2741 %withargs All data given through --with-THING options.
2742 %unified_info All information that was computed from the build.info
2751 Print a brief help message and exit.
2755 Print the manual page and exit.
2757 =item B<--dump> | B<-d>
2759 Print all relevant configuration data. This is equivalent to B<--command-line>
2760 B<--options> B<--target> B<--environment> B<--make-variables>
2761 B<--build-parameters>.
2763 =item B<--command-line> | B<-c>
2765 Print the current configuration command line.
2767 =item B<--options> | B<-o>
2769 Print the features, both enabled and disabled, and display defined macro and
2770 skipped directories where applicable.
2772 =item B<--target> | B<-t>
2774 Print the config attributes for this config target.
2776 =item B<--environment> | B<-e>
2778 Print the environment variables and their values at the time of configuration.
2780 =item B<--make-variables> | B<-m>
2782 Print the main make variables generated in the current configuration
2784 =item B<--build-parameters> | B<-b>
2786 Print the build parameters, i.e. build file and build file templates.
2788 =item B<--reconfigure> | B<--reconf> | B<-r>
2790 Redo the configuration.
