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

2762 %target The OpenSSL config target with all inheritances
2764 %disabled The features that are disabled.
2765 @disablables The list of features that can be disabled.
2766 %withargs All data given through --with-THING options.
2767 %unified_info All information that was computed from the build.info
2776 Print a brief help message and exit.
2780 Print the manual page and exit.

2786 B<--build-parameters>.
2788 =item B<--command-line> | B<-c>
2790 Print the current configuration command line.
2792 =item B<--options> | B<-o>
2794 Print the features, both enabled and disabled, and display defined macro and
2795 skipped directories where applicable.
2797 =item B<--target> | B<-t>
2799 Print the config attributes for this config target.
2801 =item B<--environment> | B<-e>
2803 Print the environment variables and their values at the time of configuration.
2805 =item B<--make-variables> | B<-m>
2807 Print the main make variables generated in the current configuration
2809 =item B<--build-parameters> | B<-b>
2811 Print the build parameters, i.e. build file and build file templates.

2858 you have tried with a current version of OpenSSL).
