27#
28# --config add the given configuration file, which will be read after
29# any "Configurations*" files that are found in the same
30# directory as this script.
31# --prefix prefix for the OpenSSL installation, which includes the
32# directories bin, lib, include, share/man, share/doc/openssl
33# This becomes the value of INSTALLTOP in Makefile
34# (Default: /usr/local)
35# --openssldir OpenSSL data area, such as openssl.cnf, certificates and keys.
36# If it's a relative directory, it will be added on the directory
37# given with --prefix.
38# This becomes the value of OPENSSLDIR in Makefile and in C.
39# (Default: PREFIX/ssl)
40#
41# --cross-compile-prefix Add specified prefix to binutils components.
42#
43# --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
44# interfaces deprecated as of the specified OpenSSL version.
45#
46# no-hw-xxx do not compile support for specific crypto hardware.
47# Generic OpenSSL-style methods relating to this support
48# are always compiled but return NULL if the hardware
49# support isn't compiled.
50# no-hw do not compile support for any crypto hardware.
51# [no-]threads [don't] try to create a library that is suitable for
52# multithreaded applications (default is "threads" if we
53# know how to do it)
54# [no-]shared [don't] try to create shared libraries when supported.
55# [no-]pic [don't] try to build position independent code when supported.
56# If disabled, it also disables shared and dynamic-engine.
57# no-asm do not use assembler
58# no-dso do not compile in any native shared-library methods. This
59# will ensure that all methods just return NULL.
60# no-egd do not compile support for the entropy-gathering daemon APIs
61# [no-]zlib [don't] compile support for zlib compression.
62# zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
63# library and will be loaded in run-time by the OpenSSL library.
64# sctp include SCTP support
65# enable-weak-ssl-ciphers
66# Enable weak ciphers that are disabled by default.
67# 386 generate 80386 code in assembly modules
68# no-sse2 disables IA-32 SSE2 code in assembly modules, the above
69# mentioned '386' option implies this one
70# no-<cipher> build without specified algorithm (rsa, idea, rc5, ...)
71# -<xxx> +<xxx> compiler options are passed through
72# -static while -static is also a pass-through compiler option (and
73# as such is limited to environments where it's actually
74# meaningful), it triggers a number configuration options,
75# namely no-dso, no-pic, no-shared and no-threads. It is
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
87# production quality.
88#
89# DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
90# provided to stack calls. Generates unique stack functions for
91# each possible stack type.
92# BN_LLONG use the type 'long long' in crypto/bn/bn.h
93# RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
94# Following are set automatically by this script
95#
96# MD5_ASM use some extra md5 assembler,
97# SHA1_ASM use some extra sha1 assembler, must define L_ENDIAN for x86

99# SHA256_ASM sha256_block is implemented in assembler

2577
2578configdata.pm - configuration data for OpenSSL builds
2579
2580=head1 SYNOPSIS
2581
2582Interactive:
2583
2584 perl configdata.pm [options]
2585
2586As data bank module:
2587
2588 use configdata;
2589
2590=head1 DESCRIPTION
2591
2592This module can be used in two modes, interactively and as a module containing
2593all the data recorded by OpenSSL's Configure script.
2594
2595When used interactively, simply run it as any perl script, with at least one
2596option, and you will get the information you ask for. See L</OPTIONS> below.
2597
2598When loaded as a module, you get a few databanks with useful information to
2599perform build related tasks. The databanks are:
2600
2601 %config Configured things.
2602 %target The OpenSSL config target with all inheritances
2603 resolved.
2604 %disabled The features that are disabled.
2605 @disablables The list of features that can be disabled.
2606 %withargs All data given through --with-THING options.
2607 %unified_info All information that was computed from the build.info
2608 files.
2609

2620Print the manual page and exit.
2621
2622=item B<--dump> | B<-d>
2623
2624Print all relevant configuration data. This is equivalent to B<--command-line>
2625B<--options> B<--target> B<--environment> B<--make-variables>
2626B<--build-parameters>.
2627
2628=item B<--command-line> | B<-c>
2629
2630Print the current configuration command line.
2631
2632=item B<--options> | B<-o>
2633
2634Print the features, both enabled and disabled, and display defined macro and
2635skipped directories where applicable.
2636
2637=item B<--target> | B<-t>
2638
2639Print the config attributes for this config target.
2640
2641=item B<--environment> | B<-e>
2642
2643Print the environment variables and their values at the time of configuration.
2644
2645=item B<--make-variables> | B<-m>
2646
2647Print the main make variables generated in the current configuration
2648
2649=item B<--build-parameters> | B<-b>
2650
2651Print the build parameters, i.e. build file and build file templates.
2652

2654
2655Redo the configuration.

2720# Note: All of the helper functions are for lazy evaluation. They all
2721# return a CODE ref, which will return the intended value when evaluated.
2722# Thus, whenever there's mention of a returned value, it's about that
2723# intended value.
2724
2725# Helper function to implement conditional inheritance depending on the
2726# value of $disabled{asm}. Used in inherit_from values as follows:

2742# debug => "debug",
2743# release => "release")

2746# "Basic string: debug", and when not, it will be "Basic string: release"
