75 | # -static while -static is also a pass-through compiler option (and |

79 | # argued that the only reason to produce statically linked | |
80 | # binaries (and in context it means executables linked with | |
81 | # -static flag, and not just executables linked with static | |
82 | # libcrypto.a) is to eliminate dependency on specific run-time, | |

84 | # to achieve just that. Unfortunately on Linux it's impossible | |
85 | # to eliminate the dependency completely for openssl executable | |
86 | # because of getaddrinfo and gethostbyname calls, which can | |
87 | # invoke dynamically loadable library facility anyway to meet | |
88 | # the lookup requests. For this reason on Linux statically | |
89 | # linked openssl executable has rather debugging value than | |

2638 | =head1 NAME | |
2639 | ||
2640 | configdata.pm - configuration data for OpenSSL builds | |
2641 | ||
2642 | =head1 SYNOPSIS | |
2643 | ||
2644 | Interactive: | |
2645 | ||
2646 | perl configdata.pm [options] | |
2647 | ||
2648 | As data bank module: | |
2649 | ||
2650 | use configdata; | |
f2d4be3b | 2651 | |
b1fafff6 RL |
2652 | =head1 DESCRIPTION |
2653 | ||
2654 | This module can be used in two modes, interactively and as a module containing | |
2655 | all the data recorded by OpenSSL's Configure script. | |
2656 | ||
2657 | When used interactively, simply run it as any perl script, with at least one | |
2658 | option, and you will get the information you ask for. See L</OPTIONS> below. | |
2659 | ||
2660 | When loaded as a module, you get a few databanks with useful information to | |
2661 | perform build related tasks. The databanks are: | |
2662 | ||
2663 | %config Configured things. | |
2664 | %target The OpenSSL config target with all inheritances | |
2665 | resolved. | |
2666 | %disabled The features that are disabled. | |
2667 | @disablables The list of features that can be disabled. | |
2668 | %withargs All data given through --with-THING options. | |
2669 | %unified_info All information that was computed from the build.info | |
2670 | files. | |

2710 | ||
2711 | =item B<--build-parameters> | B<-b> | |
2712 | ||
2713 | Print the build parameters, i.e. build file and build file templates. | |
