82 # libcrypto.a) is to eliminate dependency on specific run-time,
83 # a.k.a. libc version. The mentioned config options are meant
84 # to achieve just that. Unfortunately on Linux it's impossible
85 # to eliminate the dependency completely for openssl executable
86 # because of getaddrinfo and gethostbyname calls, which can
87 # invoke dynamically loadable library facility anyway to meet
88 # the lookup requests. For this reason on Linux statically
89 # linked openssl executable has rather debugging value than

2763 This module can be used in two modes, interactively and as a module containing
2764 all the data recorded by OpenSSL's Configure script.
2766 When used interactively, simply run it as any perl script, with at least one
2767 option, and you will get the information you ask for. See L</OPTIONS> below.
2769 When loaded as a module, you get a few databanks with useful information to
2770 perform build related tasks. The databanks are:
2772 %config Configured things.
2773 %target The OpenSSL config target with all inheritances
2775 %disabled The features that are disabled.
2776 @disablables The list of features that can be disabled.
2777 %withargs All data given through --with-THING options.
2778 %unified_info All information that was computed from the build.info
2787 Print a brief help message and exit.
2791 Print the manual page and exit.
2793 =item B<--dump> | B<-d>
2795 Print all relevant configuration data. This is equivalent to B<--command-line>
2796 B<--options> B<--target> B<--environment> B<--make-variables>
2797 B<--build-parameters>.
2799 =item B<--command-line> | B<-c>
2801 Print the current configuration command line.
2803 =item B<--options> | B<-o>
2805 Print the features, both enabled and disabled, and display defined macro and
2806 skipped directories where applicable.
2808 =item B<--target> | B<-t>
2810 Print the config attributes for this config target.
2812 =item B<--environment> | B<-e>
2814 Print the environment variables and their values at the time of configuration.
2816 =item B<--make-variables> | B<-m>
2818 Print the main make variables generated in the current configuration
2820 =item B<--build-parameters> | B<-b>
2822 Print the build parameters, i.e. build file and build file templates.
