45 | # | |
46 | # --cross-compile-prefix Add specified prefix to binutils components. | |
47 | # | |
48 | # --api One of 0.9.8, 1.0.0, 1.0.1, 1.0.2, 1.1.0, 1.1.1, or 3.0 | |
49 | # Define the public APIs as they were for that version | |
50 | # including patch releases. If 'no-deprecated' is also | |
51 | # given, do not compile support for interfaces deprecated | |
52 | # up to and including the specified OpenSSL version. | |
53 | # | |
54 | # no-hw-xxx do not compile support for specific crypto hardware. | |
55 | # Generic OpenSSL-style methods relating to this support | |
56 | # are always compiled but return NULL if the hardware | |
57 | # support isn't compiled. | |
58 | # no-hw do not compile support for any crypto hardware. | |
59 | # [no-]threads [don't] try to create a library that is suitable for | |
60 | # multithreaded applications (default is "threads" if we | |
61 | # know how to do it) | |
62 | # [no-]shared [don't] try to create shared libraries when supported. | |
63 | # [no-]pic [don't] try to build position independent code when supported. | |
64 | # If disabled, it also disables shared and dynamic-engine. | |
65 | # no-asm do not use assembler | |
66 | # no-egd do not compile support for the entropy-gathering daemon APIs | |
67 | # [no-]zlib [don't] compile support for zlib compression. | |
68 | # zlib-dynamic Like "zlib", but the zlib library is expected to be a shared | |
69 | # library and will be loaded in run-time by the OpenSSL library. | |
70 | # sctp include SCTP support | |
71 | # no-uplink Don't build support for UPLINK interface. | |
72 | # enable-weak-ssl-ciphers | |
73 | # Enable weak ciphers that are disabled by default. | |
74 | # 386 generate 80386 code in assembly modules | |
75 | # no-sse2 disables IA-32 SSE2 code in assembly modules, the above | |
76 | # mentioned '386' option implies this one | |
77 | # no-<cipher> build without specified algorithm (rsa, idea, rc5, ...) | |
78 | # -<xxx> +<xxx> All options which are unknown to the 'Configure' script are | |
79 | # /<xxx> passed through to the compiler. Unix-style options beginning | |
80 | # with a '-' or '+' are recognized, as well as Windows-style | |
81 | # options beginning with a '/'. If the option contains arguments | |
82 | # separated by spaces, then the URL-style notation %20 can be | |
83 | # used for the space character in order to avoid having to quote | |
84 | # the option. For example, -opt%20arg gets expanded to -opt arg. | |
85 | # In fact, any ASCII character can be encoded as %xx using its | |
86 | # hexadecimal encoding. | |
87 | # -static while -static is also a pass-through compiler option (and | |
88 | # as such is limited to environments where it's actually | |
89 | # meaningful), it triggers a number configuration options, | |
90 | # namely no-pic, no-shared and no-threads. It is | |
91 | # argued that the only reason to produce statically linked | |
92 | # binaries (and in context it means executables linked with | |
93 | # -static flag, and not just executables linked with static | |
94 | # libcrypto.a) is to eliminate dependency on specific run-time, | |
95 | # a.k.a. libc version. The mentioned config options are meant | |
96 | # to achieve just that. Unfortunately on Linux it's impossible | |
97 | # to eliminate the dependency completely for openssl executable | |
98 | # because of getaddrinfo and gethostbyname calls, which can | |
99 | # invoke dynamically loadable library facility anyway to meet | |
100 | # the lookup requests. For this reason on Linux statically | |
101 | # linked openssl executable has rather debugging value than | |
102 | # production quality. | |
103 | # | |
104 | # BN_LLONG use the type 'long long' in crypto/bn/bn.h | |
