28 # --prefix prefix for the OpenSSL installation, which includes the
29 # directories bin, lib, include, share/man, share/doc/openssl
30 # This becomes the value of INSTALLTOP in Makefile
31 # (Default: /usr/local)
32 # --openssldir OpenSSL data area, such as openssl.cnf, certificates and keys.
33 # If it's a relative directory, it will be added on the directory
34 # given with --prefix.

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

64 # Enable weak ciphers that are disabled by default. This currently

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