29 # --prefix prefix for the OpenSSL installation, which includes the

31 # This becomes the value of INSTALLTOP in Makefile
32 # (Default: /usr/local)

37 # (Default: PREFIX/ssl)
38 #
39 # --cross-compile-prefix Add specified prefix to binutils components.
40 #
41 # --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
42 # interfaces deprecated as of the specified OpenSSL version.
43 #
44 # no-hw-xxx do not compile support for specific crypto hardware.
45 # Generic OpenSSL-style methods relating to this support
46 # are always compiled but return NULL if the hardware
47 # support isn't compiled.
48 # no-hw do not compile support for any crypto hardware.
49 # [no-]threads [don't] try to create a library that is suitable for
50 # multithreaded applications (default is "threads" if we
51 # know how to do it)
52 # [no-]shared [don't] try to create shared libraries when supported.
53 # [no-]pic [don't] try to build position independent code when supported.
54 # If disabled, it also disables shared and dynamic-engine.
55 # no-asm do not use assembler
56 # no-dso do not compile in any native shared-library methods. This
57 # will ensure that all methods just return NULL.
58 # no-egd do not compile support for the entropy-gathering daemon APIs
59 # [no-]zlib [don't] compile support for zlib compression.
60 # zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
61 # library and will be loaded in run-time by the OpenSSL library.
62 # sctp include SCTP support
63 # enable-weak-ssl-ciphers
64 # Enable weak ciphers that are disabled by default. This currently
65 # only includes RC4 based ciphers.
66 # 386 generate 80386 code in assembly modules
67 # no-sse2 disables IA-32 SSE2 code in assembly modules, the above
68 # mentioned '386' option implies this one

70 # -<xxx> +<xxx> compiler options are passed through
71 # -static while -static is also a pass-through compiler option (and
72 # as such is limited to environments where it's actually
73 # meaningful), it triggers a number configuration options,
74 # namely no-dso, no-pic, no-shared and no-threads. It is
75 # argued that the only reason to produce statically linked
76 # binaries (and in context it means executables linked with
77 # -static flag, and not just executables linked with static
78 # libcrypto.a) is to eliminate dependency on specific run-time,
79 # a.k.a. libc version. The mentioned config options are meant
80 # to achieve just that. Unfortunately on Linux it's impossible
81 # to eliminate the dependency completely for openssl executable
82 # because of getaddrinfo and gethostbyname calls, which can
83 # invoke dynamically loadable library facility anyway to meet
84 # the lookup requests. For this reason on Linux statically
85 # linked openssl executable has rather debugging value than
86 # production quality.

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