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

2480 When used interactively, simply run it as any perl script, with at least one
2481 option, and you will get the information you ask for. See L</OPTIONS> below.
2483 When loaded as a module, you get a few databanks with useful information to
2484 perform build related tasks. The databanks are:
2486 %config Configured things.
2487 %target The OpenSSL config target with all inheritances
2489 %disabled The features that are disabled.
2490 @disablables The list of features that can be disabled.
2491 %withargs All data given through --with-THING options.
2492 %unified_info All information that was computed from the build.info

2516 =item B<--options> | B<-o>
2518 Print the features, both enabled and disabled, and display defined macro and

2527 Print the main make variables generated in the current configuration
2529 =item B<--build-parameters> | B<-b>
2531 Print the build parameters, i.e. build file and build file templates.
