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

2798 As data bank module:
2804 This module can be used in two modes, interactively and as a module containing
2805 all the data recorded by OpenSSL's Configure script.
2807 When used interactively, simply run it as any perl script, with at least one
2808 option, and you will get the information you ask for. See L</OPTIONS> below.
2810 When loaded as a module, you get a few databanks with useful information to
2811 perform build related tasks. The databanks are:
2813 %config Configured things.
2814 %target The OpenSSL config target with all inheritances
2816 %disabled The features that are disabled.
2817 @disablables The list of features that can be disabled.
2818 %withargs All data given through --with-THING options.
2819 %unified_info All information that was computed from the build.info
2828 Print a brief help message and exit.
2832 Print the manual page and exit.
2834 =item B<--dump> | B<-d>
2836 Print all relevant configuration data. This is equivalent to B<--command-line>
2837 B<--options> B<--target> B<--environment> B<--make-variables>
2838 B<--build-parameters>.
2840 =item B<--command-line> | B<-c>
2842 Print the current configuration command line.
2844 =item B<--options> | B<-o>
2846 Print the features, both enabled and disabled, and display defined macro and
2847 skipped directories where applicable.
2849 =item B<--target> | B<-t>
2851 Print the config attributes for this config target.
2853 =item B<--environment> | B<-e>
2855 Print the environment variables and their values at the time of configuration.
2857 =item B<--make-variables> | B<-m>
2859 Print the main make variables generated in the current configuration
2861 =item B<--build-parameters> | B<-b>
2863 Print the build parameters, i.e. build file and build file templates.
2865 =item B<--reconfigure> | B<--reconf> | B<-r>
2867 Redo the configuration.

2906 The options 'shared', 'pic' and 'dynamic-engine' aren't supported on this
2907 platform, so we will pretend you gave the option 'no-pic', which also disables
2908 'shared' and 'dynamic-engine'. If you know how to implement shared libraries
2909 or position independent code, please let us know (but please first make sure
2910 you have tried with a current version of OpenSSL).
