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.

89 # DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
90 # provided to stack calls. Generates unique stack functions for

2563
2564 configdata.pm - configuration data for OpenSSL builds
2565
2566 =head1 SYNOPSIS
2567
2568 Interactive:
2569
2570 perl configdata.pm [options]
2571
2572 As data bank module:
2573
2574 use configdata;
2575
2576 =head1 DESCRIPTION
2577
2578 This module can be used in two modes, interactively and as a module containing
2579 all the data recorded by OpenSSL's Configure script.
2580
2581 When used interactively, simply run it as any perl script, with at least one
2582 option, and you will get the information you ask for. See L</OPTIONS> below.
2583
2584 When loaded as a module, you get a few databanks with useful information to
2585 perform build related tasks. The databanks are:
2586
2587 %config Configured things.
2588 %target The OpenSSL config target with all inheritances
2589 resolved.
2590 %disabled The features that are disabled.
2591 @disablables The list of features that can be disabled.
2592 %withargs All data given through --with-THING options.
2593 %unified_info All information that was computed from the build.info
2594 files.
