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.

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
