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 | |

2727 | =head1 NAME | |
2728 | ||
2729 | configdata.pm - configuration data for OpenSSL builds | |
2730 | ||
2731 | =head1 SYNOPSIS | |
2732 | ||
2733 | Interactive: | |
2734 | ||
2735 | perl configdata.pm [options] | |
2736 | ||
2737 | As data bank module: | |
2738 | ||
2739 | use configdata; | |
f2d4be3b | 2740 | |
b1fafff6 RL |
2741 | =head1 DESCRIPTION |
2742 | ||
2743 | This module can be used in two modes, interactively and as a module containing | |
2744 | all the data recorded by OpenSSL's Configure script. | |
2745 | ||
2746 | When used interactively, simply run it as any perl script, with at least one | |
2747 | option, and you will get the information you ask for. See L</OPTIONS> below. | |
2748 | ||
2749 | When loaded as a module, you get a few databanks with useful information to | |
2750 | perform build related tasks. The databanks are: | |
2751 | ||
2752 | %config Configured things. | |
2753 | %target The OpenSSL config target with all inheritances | |
2754 | resolved. | |
2755 | %disabled The features that are disabled. | |
2756 | @disablables The list of features that can be disabled. | |
2757 | %withargs All data given through --with-THING options. | |
2758 | %unified_info All information that was computed from the build.info | |
2759 | files. | |
2760 | ||

2786 | skipped directories where applicable. | |
2787 | ||

2797 | ||
2798 | Print the main make variables generated in the current configuration | |
2799 | ||
2800 | =item B<--build-parameters> | B<-b> | |
2801 | ||
2802 | Print the build parameters, i.e. build file and build file templates. | |
