76 # -static while -static is also a pass-through compiler option (and
77 # as such is limited to environments where it's actually
78 # meaningful), it triggers a number configuration options,
79 # namely no-dso, no-pic, no-shared and no-threads. It is
80 # argued that the only reason to produce statically linked
81 # binaries (and in context it means executables linked with
82 # -static flag, and not just executables linked with static
83 # libcrypto.a) is to eliminate dependency on specific run-time,
84 # a.k.a. libc version. The mentioned config options are meant
85 # to achieve just that. Unfortunately on Linux it's impossible
86 # to eliminate the dependency completely for openssl executable
87 # because of getaddrinfo and gethostbyname calls, which can
88 # invoke dynamically loadable library facility anyway to meet
89 # the lookup requests. For this reason on Linux statically
90 # linked openssl executable has rather debugging value than
93 # DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
94 # provided to stack calls. Generates unique stack functions for

2779 This module can be used in two modes, interactively and as a module containing
2780 all the data recorded by OpenSSL's Configure script.
2782 When used interactively, simply run it as any perl script, with at least one
2783 option, and you will get the information you ask for. See L</OPTIONS> below.
2785 When loaded as a module, you get a few databanks with useful information to
2786 perform build related tasks. The databanks are:
2788 %config Configured things.
2789 %target The OpenSSL config target with all inheritances
2791 %disabled The features that are disabled.
2792 @disablables The list of features that can be disabled.
2793 %withargs All data given through --with-THING options.
2794 %unified_info All information that was computed from the build.info
2803 Print a brief help message and exit.
2807 Print the manual page and exit.
2809 =item B<--dump> | B<-d>
2811 Print all relevant configuration data. This is equivalent to B<--command-line>
2812 B<--options> B<--target> B<--environment> B<--make-variables>
2813 B<--build-parameters>.
2815 =item B<--command-line> | B<-c>
2817 Print the current configuration command line.
2819 =item B<--options> | B<-o>
2821 Print the features, both enabled and disabled, and display defined macro and
2822 skipped directories where applicable.
2824 =item B<--target> | B<-t>
2826 Print the config attributes for this config target.
2828 =item B<--environment> | B<-e>
2830 Print the environment variables and their values at the time of configuration.
2832 =item B<--make-variables> | B<-m>
2834 Print the main make variables generated in the current configuration
2836 =item B<--build-parameters> | B<-b>
2838 Print the build parameters, i.e. build file and build file templates.
2840 =item B<--reconfigure> | B<--reconf> | B<-r>
2842 Redo the configuration.
