78 # argued that the only reason to produce statically linked

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

2765 As data bank module:
2771 This module can be used in two modes, interactively and as a module containing
2772 all the data recorded by OpenSSL's Configure script.
2774 When used interactively, simply run it as any perl script, with at least one
2775 option, and you will get the information you ask for. See L</OPTIONS> below.
2777 When loaded as a module, you get a few databanks with useful information to
2778 perform build related tasks. The databanks are:
2780 %config Configured things.
2781 %target The OpenSSL config target with all inheritances
2783 %disabled The features that are disabled.
2784 @disablables The list of features that can be disabled.
2785 %withargs All data given through --with-THING options.
2786 %unified_info All information that was computed from the build.info
2795 Print a brief help message and exit.
2799 Print the manual page and exit.
2801 =item B<--dump> | B<-d>
2803 Print all relevant configuration data. This is equivalent to B<--command-line>
2804 B<--options> B<--target> B<--environment> B<--make-variables>
2805 B<--build-parameters>.
2807 =item B<--command-line> | B<-c>
2809 Print the current configuration command line.
2811 =item B<--options> | B<-o>
2813 Print the features, both enabled and disabled, and display defined macro and
2814 skipped directories where applicable.
2816 =item B<--target> | B<-t>
2818 Print the config attributes for this config target.
2820 =item B<--environment> | B<-e>
2822 Print the environment variables and their values at the time of configuration.
2824 =item B<--make-variables> | B<-m>
2826 Print the main make variables generated in the current configuration
2828 =item B<--build-parameters> | B<-b>
2830 Print the build parameters, i.e. build file and build file templates.
2832 =item B<--reconfigure> | B<--reconf> | B<-r>
