79 # argued that the only reason to produce statically linked
80 # binaries (and in context it means executables linked with
81 # -static flag, and not just executables linked with static
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

2596 When used interactively, simply run it as any perl script, with at least one

2600 perform build related tasks. The databanks are:
2602 %config Configured things.
2603 %target The OpenSSL config target with all inheritances
2605 %disabled The features that are disabled.
2606 @disablables The list of features that can be disabled.
2607 %withargs All data given through --with-THING options.
2608 %unified_info All information that was computed from the build.info
2617 Print a brief help message and exit.
2621 Print the manual page and exit.

2627 B<--build-parameters>.
2629 =item B<--command-line> | B<-c>

2633 =item B<--options> | B<-o>
2635 Print the features, both enabled and disabled, and display defined macro and
2636 skipped directories where applicable.
2638 =item B<--target> | B<-t>
2640 Print the config attributes for this config target.
2642 =item B<--environment> | B<-e>
2644 Print the environment variables and their values at the time of configuration.
2646 =item B<--make-variables> | B<-m>
2648 Print the main make variables generated in the current configuration
2650 =item B<--build-parameters> | B<-b>
2652 Print the build parameters, i.e. build file and build file templates.
