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

35 # --install_prefix Additional prefix for package builders (empty by
36 # default). This needn't be set in advance, you can
37 # just as well use "make INSTALL_PREFIX=/whatever install".
39 # --cross-compile-prefix Add specified prefix to binutils components.
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.
44 # no-hw-xxx do not compile support for specific crypto hardware.

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.

50 # multithreaded applications (default is "threads" if we
52 # [no-]shared [don't] try to create shared libraries when supported.
53 # no-asm do not use assembler
54 # no-dso do not compile in any native shared-library methods. This
55 # will ensure that all methods just return NULL.
56 # no-egd do not compile support for the entropy-gathering daemon APIs
57 # [no-]zlib [don't] compile support for zlib compression.
58 # zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
59 # library and will be loaded in run-time by the OpenSSL library.
