78 # argued that the only reason to produce statically linked
79 # binaries (and in context it means executables linked with
80 # -static flag, and not just executables linked with static
81 # libcrypto.a) is to eliminate dependency on specific run-time,
82 # a.k.a. libc version. The mentioned config options are meant
83 # to achieve just that. Unfortunately on Linux it's impossible
84 # to eliminate the dependency completely for openssl executable
85 # because of getaddrinfo and gethostbyname calls, which can
86 # invoke dynamically loadable library facility anyway to meet
87 # the lookup requests. For this reason on Linux statically
88 # linked openssl executable has rather debugging value than

2713 This module can be used in two modes, interactively and as a module containing
2714 all the data recorded by OpenSSL's Configure script.
2716 When used interactively, simply run it as any perl script, with at least one
2717 option, and you will get the information you ask for. See L</OPTIONS> below.
2719 When loaded as a module, you get a few databanks with useful information to
2720 perform build related tasks. The databanks are:
2722 %config Configured things.
2723 %target The OpenSSL config target with all inheritances
2725 %disabled The features that are disabled.
2726 @disablables The list of features that can be disabled.
2727 %withargs All data given through --with-THING options.
2728 %unified_info All information that was computed from the build.info
2737 Print a brief help message and exit.
2741 Print the manual page and exit.
2743 =item B<--dump> | B<-d>
2745 Print all relevant configuration data. This is equivalent to B<--command-line>
2746 B<--options> B<--target> B<--environment> B<--make-variables>
2747 B<--build-parameters>.
2749 =item B<--command-line> | B<-c>
2751 Print the current configuration command line.
2753 =item B<--options> | B<-o>
2755 Print the features, both enabled and disabled, and display defined macro and
2756 skipped directories where applicable.
2758 =item B<--target> | B<-t>
2760 Print the config attributes for this config target.
2762 =item B<--environment> | B<-e>
2764 Print the environment variables and their values at the time of configuration.
