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
91 # each possible stack type.

2552 configdata.pm - configuration data for OpenSSL builds
2558 perl configdata.pm [options]
2560 As data bank module:
2566 This module can be used in two modes, interactively and as a module containing
2567 all the data recorded by OpenSSL's Configure script.
2569 When used interactively, simply run it as any perl script, with at least one
2570 option, and you will get the information you ask for. See L</OPTIONS> below.
2572 When loaded as a module, you get a few databanks with useful information to
2573 perform build related tasks. The databanks are:
2575 %config Configured things.
2576 %target The OpenSSL config target with all inheritances
2578 %disabled The features that are disabled.
2579 @disablables The list of features that can be disabled.
2580 %withargs All data given through --with-THING options.
2581 %unified_info All information that was computed from the build.info
2590 Print a brief help message and exit.
2594 Print the manual page and exit.
2596 =item B<--dump> | B<-d>
2598 Print all relevant configuration data. This is equivalent to B<--command-line>
2599 B<--options> B<--target> B<--environment> B<--make-variables>
2600 B<--build-parameters>.
2602 =item B<--command-line> | B<-c>
2604 Print the current configuration command line.
2606 =item B<--options> | B<-o>
2608 Print the features, both enabled and disabled, and display defined macro and
2609 skipped directories where applicable.
2611 =item B<--target> | B<-t>
2613 Print the config attributes for this config target.
2615 =item B<--environment> | B<-e>
2617 Print the environment variables and their values at the time of configuration.
2619 =item B<--make-variables> | B<-m>
2621 Print the main make variables generated in the current configuration
2623 =item B<--build-parameters> | B<-b>
2625 Print the build parameters, i.e. build file and build file templates.
2627 =item B<--reconfigure> | B<--reconf> | B<-r>
2629 Redo the configuration.
2631 =item B<--verbose> | B<-v>

2660 applications as the compiler options required on this system are not known.
2661 See file INSTALL for details if you need multi-threading.

2666 The options 'shared', 'pic' and 'dynamic-engine' aren't supported on this
2667 platform, so we will pretend you gave the option 'no-pic', which also disables
2668 'shared' and 'dynamic-engine'. If you know how to implement shared libraries
2669 or position independent code, please let us know (but please first make sure
2670 you have tried with a current version of OpenSSL).
