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

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

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