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

2800 As data bank module:
2806 This module can be used in two modes, interactively and as a module containing
2807 all the data recorded by OpenSSL's Configure script.
2809 When used interactively, simply run it as any perl script, with at least one
2810 option, and you will get the information you ask for. See L</OPTIONS> below.
2812 When loaded as a module, you get a few databanks with useful information to
2813 perform build related tasks. The databanks are:
2815 %config Configured things.
2816 %target The OpenSSL config target with all inheritances
2818 %disabled The features that are disabled.
2819 @disablables The list of features that can be disabled.
2820 %withargs All data given through --with-THING options.
2821 %unified_info All information that was computed from the build.info
2830 Print a brief help message and exit.
2834 Print the manual page and exit.
2836 =item B<--dump> | B<-d>
2838 Print all relevant configuration data. This is equivalent to B<--command-line>
2839 B<--options> B<--target> B<--environment> B<--make-variables>
2840 B<--build-parameters>.
2842 =item B<--command-line> | B<-c>
2844 Print the current configuration command line.
2846 =item B<--options> | B<-o>
2848 Print the features, both enabled and disabled, and display defined macro and
2849 skipped directories where applicable.
2851 =item B<--target> | B<-t>
2853 Print the config attributes for this config target.
2855 =item B<--environment> | B<-e>
2857 Print the environment variables and their values at the time of configuration.
2859 =item B<--make-variables> | B<-m>
2861 Print the main make variables generated in the current configuration
2863 =item B<--build-parameters> | B<-b>
2865 Print the build parameters, i.e. build file and build file templates.
2867 =item B<--reconfigure> | B<--reconf> | B<-r>
2869 Redo the configuration.

2908 The options 'shared', 'pic' and 'dynamic-engine' aren't supported on this
2909 platform, so we will pretend you gave the option 'no-pic', which also disables
2910 'shared' and 'dynamic-engine'. If you know how to implement shared libraries
2911 or position independent code, please let us know (but please first make sure
2912 you have tried with a current version of OpenSSL).
