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

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

2703 When used interactively, simply run it as any perl script, with at least one
2704 option, and you will get the information you ask for. See L</OPTIONS> below.

2707 perform build related tasks. The databanks are:
2709 %config Configured things.
2710 %target The OpenSSL config target with all inheritances
2712 %disabled The features that are disabled.
2713 @disablables The list of features that can be disabled.
2714 %withargs All data given through --with-THING options.
2715 %unified_info All information that was computed from the build.info
2724 Print a brief help message and exit.
