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

047d97af AP |
78 | # argued that the only reason to produce statically linked |
79 | # binaries (and in context it means executables linked with | |
80 | # -static flag, and not just executables linked with static | |
81 | # libcrypto.a) is to eliminate dependency on specific run-time, | |
82 | # a.k.a. libc version. The mentioned config options are meant | |
83 | # to achieve just that. Unfortunately on Linux it's impossible | |
84 | # to eliminate the dependency completely for openssl executable | |
85 | # because of getaddrinfo and gethostbyname calls, which can | |
86 | # invoke dynamically loadable library facility anyway to meet | |
87 | # the lookup requests. For this reason on Linux statically | |
88 | # linked openssl executable has rather debugging value than | |
89 | # production quality. | |

2755 | =head1 NAME | |
2756 | ||
2757 | configdata.pm - configuration data for OpenSSL builds | |
2758 | ||
2759 | =head1 SYNOPSIS | |
2760 | ||
2761 | Interactive: | |
2762 | ||
2763 | perl configdata.pm [options] | |
2764 | ||
2765 | As data bank module: | |
2766 | ||
2767 | use configdata; | |
f2d4be3b | 2768 | |
b1fafff6 RL |
2769 | =head1 DESCRIPTION |
2770 | ||
2771 | This module can be used in two modes, interactively and as a module containing | |
2772 | all the data recorded by OpenSSL's Configure script. | |
2773 | ||
2774 | When used interactively, simply run it as any perl script, with at least one | |
2775 | option, and you will get the information you ask for. See L</OPTIONS> below. | |
2776 | ||
2777 | When loaded as a module, you get a few databanks with useful information to | |
2778 | perform build related tasks. The databanks are: | |
2779 | ||
2780 | %config Configured things. | |
2781 | %target The OpenSSL config target with all inheritances | |
2782 | resolved. | |
2783 | %disabled The features that are disabled. | |
2784 | @disablables The list of features that can be disabled. | |
2785 | %withargs All data given through --with-THING options. | |
2786 | %unified_info All information that was computed from the build.info | |
2787 | files. | |
2788 | ||

2827 | ||
2828 | =item B<--build-parameters> | B<-b> | |
2829 | ||
