81 # libcrypto.a) is to eliminate dependency on specific run-time,

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

2760 This module can be used in two modes, interactively and as a module containing
2761 all the data recorded by OpenSSL's Configure script.
2763 When used interactively, simply run it as any perl script, with at least one
2764 option, and you will get the information you ask for. See L</OPTIONS> below.
2766 When loaded as a module, you get a few databanks with useful information to
2767 perform build related tasks. The databanks are:
2769 %config Configured things.
2770 %target The OpenSSL config target with all inheritances
2772 %disabled The features that are disabled.
2773 @disablables The list of features that can be disabled.
2774 %withargs All data given through --with-THING options.
