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
40 # given with --prefix.
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-dso do not compile in any native shared-library methods. This
62 # will ensure that all methods just return NULL.
63 # no-egd do not compile support for the entropy-gathering daemon APIs
64 # [no-]zlib [don't] compile support for zlib compression.
65 # zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
66 # library and will be loaded in run-time by the OpenSSL library.
67 # sctp include SCTP support
68 # enable-weak-ssl-ciphers
69 # Enable weak ciphers that are disabled by default.
70 # 386 generate 80386 code in assembly modules
71 # no-sse2 disables IA-32 SSE2 code in assembly modules, the above
72 # mentioned '386' option implies this one
73 # no-<cipher> build without specified algorithm (rsa, idea, rc5, ...)
74 # -<xxx> +<xxx> compiler options are passed through
75 # -static while -static is also a pass-through compiler option (and
76 # as such is limited to environments where it's actually
77 # meaningful), it triggers a number configuration options,
78 # namely no-dso, no-pic, no-shared and no-threads. It is
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,
83 # a.k.a. libc version. The mentioned config options are meant
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
90 # production quality.

92 # DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
93 # provided to stack calls. Generates unique stack functions for
94 # each possible stack type.

96 # RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h

2642 =head1 NAME
2643
2644 configdata.pm - configuration data for OpenSSL builds
2645
2646 =head1 SYNOPSIS
2647
2648 Interactive:
2649
2650 perl configdata.pm [options]
2651
2652 As data bank module:
2653
2654 use configdata;
2655
2656 =head1 DESCRIPTION
2657
2658 This module can be used in two modes, interactively and as a module containing
2659 all the data recorded by OpenSSL's Configure script.
2660
2661 When used interactively, simply run it as any perl script, with at least one
2662 option, and you will get the information you ask for. See L</OPTIONS> below.
2663
2664 When loaded as a module, you get a few databanks with useful information to
2665 perform build related tasks. The databanks are:
2666
2667 %config Configured things.
2668 %target The OpenSSL config target with all inheritances
2669 resolved.
2670 %disabled The features that are disabled.
2671 @disablables The list of features that can be disabled.
2672 %withargs All data given through --with-THING options.
2673 %unified_info All information that was computed from the build.info
2674 files.

2701 skipped directories where applicable.
