34# --prefix prefix for the OpenSSL installation, which includes the
35# directories bin, lib, include, share/man, share/doc/openssl
36# This becomes the value of INSTALLTOP in Makefile
37# (Default: /usr/local)
38# --openssldir OpenSSL data area, such as openssl.cnf, certificates and keys.
39# If it's a relative directory, it will be added on the directory

41# This becomes the value of OPENSSLDIR in Makefile and in C.
42# (Default: PREFIX/ssl)
43#
44# --cross-compile-prefix Add specified prefix to binutils components.
45#
46# --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
47# interfaces deprecated as of the specified OpenSSL version.
48#
49# no-hw-xxx do not compile support for specific crypto hardware.
50# Generic OpenSSL-style methods relating to this support
51# are always compiled but return NULL if the hardware
52# support isn't compiled.
53# no-hw do not compile support for any crypto hardware.
54# [no-]threads [don't] try to create a library that is suitable for
55# multithreaded applications (default is "threads" if we
56# know how to do it)
57# [no-]shared [don't] try to create shared libraries when supported.
58# [no-]pic [don't] try to build position independent code when supported.
59# If disabled, it also disables shared and dynamic-engine.
60# no-asm do not use assembler
61# no-egd do not compile support for the entropy-gathering daemon APIs
62# [no-]zlib [don't] compile support for zlib compression.
63# zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
64# library and will be loaded in run-time by the OpenSSL library.
65# sctp include SCTP support
66# enable-weak-ssl-ciphers
67# Enable weak ciphers that are disabled by default.
68# 386 generate 80386 code in assembly modules
69# no-sse2 disables IA-32 SSE2 code in assembly modules, the above
70# mentioned '386' option implies this one
71# no-<cipher> build without specified algorithm (rsa, idea, rc5, ...)
72# -<xxx> +<xxx> All options which are unknown to the 'Configure' script are
73# /<xxx> passed through to the compiler. Unix-style options beginning
74# with a '-' or '+' are recognized, as well as Windows-style
75# options beginning with a '/'. If the option contains arguments
76# separated by spaces, then the URL-style notation %20 can be
77# used for the space character in order to avoid having to quote
78# the option. For example, -opt%20arg gets expanded to -opt arg.
79# In fact, any ASCII character can be encoded as %xx using its
80# hexadecimal encoding.
81# -static while -static is also a pass-through compiler option (and
82# as such is limited to environments where it's actually
83# meaningful), it triggers a number configuration options,
84# namely no-pic, no-shared and no-threads. It is
85# argued that the only reason to produce statically linked
86# binaries (and in context it means executables linked with
87# -static flag, and not just executables linked with static
88# libcrypto.a) is to eliminate dependency on specific run-time,
89# a.k.a. libc version. The mentioned config options are meant
90# to achieve just that. Unfortunately on Linux it's impossible
91# to eliminate the dependency completely for openssl executable
92# because of getaddrinfo and gethostbyname calls, which can
93# invoke dynamically loadable library facility anyway to meet
94# the lookup requests. For this reason on Linux statically
95# linked openssl executable has rather debugging value than
96# production quality.
97#
98# BN_LLONG use the type 'long long' in crypto/bn/bn.h
99# RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
100# Following are set automatically by this script
101#
102# MD5_ASM use some extra md5 assembler,
103# SHA1_ASM use some extra sha1 assembler, must define L_ENDIAN for x86

121# long' not being supported. As 64-bit algorithms are common now,
122# it grew impossible to resolve this without sizeable additional

2718
2719configdata.pm - configuration data for OpenSSL builds
2720
2721=head1 SYNOPSIS
2722
2723Interactive:
2724
2725 perl configdata.pm [options]
2726
2727As data bank module:
2728
2729 use configdata;
2730
2731=head1 DESCRIPTION
2732
2733This module can be used in two modes, interactively and as a module containing
2734all the data recorded by OpenSSL's Configure script.
2735
2736When used interactively, simply run it as any perl script, with at least one
2737option, and you will get the information you ask for. See L</OPTIONS> below.
2738
2739When loaded as a module, you get a few databanks with useful information to
2740perform build related tasks. The databanks are:
2741
2742 %config Configured things.
2743 %target The OpenSSL config target with all inheritances
2744 resolved.
2745 %disabled The features that are disabled.
2746 @disablables The list of features that can be disabled.
2747 %withargs All data given through --with-THING options.
2748 %unified_info All information that was computed from the build.info
2749 files.
2750
2751=head1 OPTIONS
2752

2761Print the manual page and exit.
2762
2763=item B<--dump> | B<-d>
2764
2765Print all relevant configuration data. This is equivalent to B<--command-line>
2766B<--options> B<--target> B<--environment> B<--make-variables>
2767B<--build-parameters>.
2768
2769=item B<--command-line> | B<-c>
2770
2771Print the current configuration command line.
2772
2773=item B<--options> | B<-o>
2774
2775Print the features, both enabled and disabled, and display defined macro and
2776skipped directories where applicable.
2777
2778=item B<--target> | B<-t>
2779
2780Print the config attributes for this config target.
2781
2782=item B<--environment> | B<-e>
2783
2784Print the environment variables and their values at the time of configuration.
2785
2786=item B<--make-variables> | B<-m>
2787
2788Print the main make variables generated in the current configuration
2789
2790=item B<--build-parameters> | B<-b>
2791
2792Print the build parameters, i.e. build file and build file templates.
2793
2794=item B<--reconfigure> | B<--reconf> | B<-r>
2795
2796Redo the configuration.
2797

2837'shared' and 'dynamic-engine'. If you know how to implement shared libraries

2839you have tried with a current version of OpenSSL).
