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

94 # provided to stack calls. Generates unique stack functions for

2786 This module can be used in two modes, interactively and as a module containing
2787 all the data recorded by OpenSSL's Configure script.
2789 When used interactively, simply run it as any perl script, with at least one
2790 option, and you will get the information you ask for. See L</OPTIONS> below.
2792 When loaded as a module, you get a few databanks with useful information to
2793 perform build related tasks. The databanks are:
2795 %config Configured things.
2796 %target The OpenSSL config target with all inheritances
2798 %disabled The features that are disabled.
2799 @disablables The list of features that can be disabled.
2800 %withargs All data given through --with-THING options.
2801 %unified_info All information that was computed from the build.info
2810 Print a brief help message and exit.
2814 Print the manual page and exit.
2816 =item B<--dump> | B<-d>
2818 Print all relevant configuration data. This is equivalent to B<--command-line>
2819 B<--options> B<--target> B<--environment> B<--make-variables>
2820 B<--build-parameters>.
2822 =item B<--command-line> | B<-c>
2824 Print the current configuration command line.
2826 =item B<--options> | B<-o>
2828 Print the features, both enabled and disabled, and display defined macro and
2829 skipped directories where applicable.
2831 =item B<--target> | B<-t>
2833 Print the config attributes for this config target.
2835 =item B<--environment> | B<-e>
2837 Print the environment variables and their values at the time of configuration.
2839 =item B<--make-variables> | B<-m>
2841 Print the main make variables generated in the current configuration
2843 =item B<--build-parameters> | B<-b>
2845 Print the build parameters, i.e. build file and build file templates.
