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

2692 When loaded as a module, you get a few databanks with useful information to
2693 perform build related tasks. The databanks are:
2695 %config Configured things.
2696 %target The OpenSSL config target with all inheritances
2698 %disabled The features that are disabled.
2699 @disablables The list of features that can be disabled.
2700 %withargs All data given through --with-THING options.
2701 %unified_info All information that was computed from the build.info
2710 Print a brief help message and exit.
2714 Print the manual page and exit.
2716 =item B<--dump> | B<-d>
2718 Print all relevant configuration data. This is equivalent to B<--command-line>
2719 B<--options> B<--target> B<--environment> B<--make-variables>
2720 B<--build-parameters>.
2722 =item B<--command-line> | B<-c>
2724 Print the current configuration command line.
2726 =item B<--options> | B<-o>
2728 Print the features, both enabled and disabled, and display defined macro and
2729 skipped directories where applicable.
2731 =item B<--target> | B<-t>
2733 Print the config attributes for this config target.
2735 =item B<--environment> | B<-e>
2737 Print the environment variables and their values at the time of configuration.
2739 =item B<--make-variables> | B<-m>
2741 Print the main make variables generated in the current configuration
2743 =item B<--build-parameters> | B<-b>
2745 Print the build parameters, i.e. build file and build file templates.
2747 =item B<--reconfigure> | B<--reconf> | B<-r>

2792 you have tried with a current version of OpenSSL).
