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

2749 all the data recorded by OpenSSL's Configure script.
2751 When used interactively, simply run it as any perl script, with at least one
2752 option, and you will get the information you ask for. See L</OPTIONS> below.
2754 When loaded as a module, you get a few databanks with useful information to
2755 perform build related tasks. The databanks are:
2757 %config Configured things.
2758 %target The OpenSSL config target with all inheritances
2760 %disabled The features that are disabled.
2761 @disablables The list of features that can be disabled.
