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 | |

2494 | ||
2495 | configdata.pm - configuration data for OpenSSL builds | |
2496 | ||
2497 | =head1 SYNOPSIS | |
2498 | ||
2499 | Interactive: | |
2500 | ||
2501 | perl configdata.pm [options] | |
2502 | ||
2503 | As data bank module: | |
2504 | ||
2505 | use configdata; | |
f2d4be3b | 2506 | |
b1fafff6 RL |
2507 | =head1 DESCRIPTION |
2508 | ||
2509 | This module can be used in two modes, interactively and as a module containing | |
2510 | all the data recorded by OpenSSL's Configure script. | |
2511 | ||
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. | |
2514 | ||
2515 | When loaded as a module, you get a few databanks with useful information to | |
2516 | perform build related tasks. The databanks are: | |
2517 | ||
2518 | %config Configured things. | |
2519 | %target The OpenSSL config target with all inheritances | |
2520 | resolved. | |
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 | |
2525 | files. | |
2526 | ||
2527 | =head1 OPTIONS | |
2528 | ||
2529 | =over 4 | |
2530 | ||

2548 | ||
ca372414 RL |
2549 | =item B<--options> | B<-o> |
2550 | ||
2551 | Print the features, both enabled and disabled, and display defined macro and | |
2552 | skipped directories where applicable. | |
2553 | ||
50ea9d2b RL |
2554 | =item B<--target> | B<-t> |
2555 | ||
2556 | Print the config attributes for this config target. | |
2557 | ||
b1fafff6 RL |
2558 | =item B<--environment> | B<-e> |
2559 | ||
2560 | Print the environment variables and their values at the time of configuration. | |
2561 | ||
2562 | =item B<--make-variables> | B<-m> | |
2563 | ||
2564 | Print the main make variables generated in the current configuration | |
2565 | ||
2566 | =item B<--build-parameters> | B<-b> | |
2567 | ||
2568 | Print the build parameters, i.e. build file and build file templates. | |
2569 | ||
2570 | =item B<--reconfigure> | B<--reconf> | B<-r> | |
2571 | ||
2572 | Redo the configuration. | |
2573 | ||
