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

2512 When used interactively, simply run it as any perl script, with at least one
2513 option, and you will get the information you ask for. See L</OPTIONS> below.
2515 When loaded as a module, you get a few databanks with useful information to
2516 perform build related tasks. The databanks are:
2518 %config Configured things.
2519 %target The OpenSSL config target with all inheritances
2521 %disabled The features that are disabled.
2522 @disablables The list of features that can be disabled.
2523 %withargs All data given through --with-THING options.
2524 %unified_info All information that was computed from the build.info
2533 Print a brief help message and exit.
2537 Print the manual page and exit.

2545 =item B<--command-line> | B<-c>

2562 =item B<--make-variables> | B<-m>
2564 Print the main make variables generated in the current configuration
2566 =item B<--build-parameters> | B<-b>
