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

2661 This module can be used in two modes, interactively and as a module containing
2662 all the data recorded by OpenSSL's Configure script.
2664 When used interactively, simply run it as any perl script, with at least one
2665 option, and you will get the information you ask for. See L</OPTIONS> below.
2667 When loaded as a module, you get a few databanks with useful information to
2668 perform build related tasks. The databanks are:
2670 %config Configured things.
2671 %target The OpenSSL config target with all inheritances
2673 %disabled The features that are disabled.
2674 @disablables The list of features that can be disabled.
2675 %withargs All data given through --with-THING options.
2676 %unified_info All information that was computed from the build.info
2685 Print a brief help message and exit.
2689 Print the manual page and exit.
2691 =item B<--dump> | B<-d>
2693 Print all relevant configuration data. This is equivalent to B<--command-line>
2694 B<--options> B<--target> B<--environment> B<--make-variables>
2695 B<--build-parameters>.
2697 =item B<--command-line> | B<-c>
2699 Print the current configuration command line.
2701 =item B<--options> | B<-o>
2703 Print the features, both enabled and disabled, and display defined macro and
2704 skipped directories where applicable.
2706 =item B<--target> | B<-t>
2708 Print the config attributes for this config target.
2710 =item B<--environment> | B<-e>
2712 Print the environment variables and their values at the time of configuration.
2714 =item B<--make-variables> | B<-m>
2716 Print the main make variables generated in the current configuration
2718 =item B<--build-parameters> | B<-b>
2720 Print the build parameters, i.e. build file and build file templates.
