73 # -static while -static is also a pass-through compiler option (and
74 # as such is limited to environments where it's actually
75 # meaningful), it triggers a number configuration options,
76 # namely no-pic, no-shared and no-threads. It is
77 # argued that the only reason to produce statically linked
78 # binaries (and in context it means executables linked with
79 # -static flag, and not just executables linked with static
80 # libcrypto.a) is to eliminate dependency on specific run-time,
81 # a.k.a. libc version. The mentioned config options are meant
82 # to achieve just that. Unfortunately on Linux it's impossible
83 # to eliminate the dependency completely for openssl executable
84 # because of getaddrinfo and gethostbyname calls, which can
85 # invoke dynamically loadable library facility anyway to meet
86 # the lookup requests. For this reason on Linux statically
87 # linked openssl executable has rather debugging value than

91 # provided to stack calls. Generates unique stack functions for

2671 This module can be used in two modes, interactively and as a module containing
2672 all the data recorded by OpenSSL's Configure script.
2674 When used interactively, simply run it as any perl script, with at least one
2675 option, and you will get the information you ask for. See L</OPTIONS> below.
2677 When loaded as a module, you get a few databanks with useful information to
2678 perform build related tasks. The databanks are:
2680 %config Configured things.
2681 %target The OpenSSL config target with all inheritances
2683 %disabled The features that are disabled.
2684 @disablables The list of features that can be disabled.
2685 %withargs All data given through --with-THING options.
2686 %unified_info All information that was computed from the build.info
2695 Print a brief help message and exit.
2699 Print the manual page and exit.
2701 =item B<--dump> | B<-d>
