# Options:
20
#
21 22 23
# --config      add the given configuration file, which will be read after
#               any "Configurations*" files that are found in the same
#               directory as this script.
24 25 26 27 28 29 30 31 32
# --prefix      prefix for the OpenSSL installation, which includes the
#               directories bin, lib, include, share/man, share/doc/openssl
#               This becomes the value of INSTALLTOP in Makefile
#               (Default: /usr/local)
# --openssldir  OpenSSL data area, such as openssl.cnf, certificates and keys.
#               If it's a relative directory, it will be added on the directory
#               given with --prefix.
#               This becomes the value of OPENSSLDIR in Makefile and in C.
#               (Default: PREFIX/ssl)
33 34 35 36 37
#
# --install_prefix  Additional prefix for package builders (empty by
#               default).  This needn't be set in advance, you can
#               just as well use "make INSTALL_PREFIX=/whatever install".
#
38 39
# --cross-compile-prefix Add specified prefix to binutils components.
#
40 41 42
# --api         One of 0.9.8, 1.0.0 or 1.1.0.  Do not compile support for
#               interfaces deprecated as of the specified OpenSSL version.
#
43 44 45 46 47
# no-hw-xxx     do not compile support for specific crypto hardware.
#               Generic OpenSSL-style methods relating to this support
#               are always compiled but return NULL if the hardware
#               support isn't compiled.
# no-hw         do not compile support for any crypto hardware.
48 49 50
# [no-]threads  [don't] try to create a library that is suitable for
#               multithreaded applications (default is "threads" if we
#               know how to do it)
51
# [no-]shared	[don't] try to create shared libraries when supported.
U
Ulf Möller 已提交
52
# no-asm        do not use assembler
53 54
# no-dso        do not compile in any native shared-library methods. This
#               will ensure that all methods just return NULL.
55
# no-egd        do not compile support for the entropy-gathering daemon APIs
56 57 58
# [no-]zlib     [don't] compile support for zlib compression.
# zlib-dynamic	Like "zlib", but the zlib library is expected to be a shared
#		library and will be loaded in run-time by the OpenSSL library.

# DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
#		provided to stack calls. Generates unique stack functions for

68 69 70 71 72 73 74 75 76
# DES_PTR	use pointer lookup vs arrays in the DES in crypto/des/des_locl.h
# DES_RISC1	use different DES_ENCRYPT macro that helps reduce register
#		dependancies but needs to more registers, good for RISC CPU's
# DES_RISC2	A different RISC variant.
# DES_UNROLL	unroll the inner DES loop, sometimes helps, somtimes hinders.
# DES_INT	use 'int' instead of 'long' for DES_LONG in crypto/des/des.h
#		This is used on the DEC Alpha where long is 8 bytes
#		and int is 4
# BN_LLONG	use the type 'long long' in crypto/bn/bn.h
77 78
# MD2_CHAR	use 'char' instead of 'int' for MD2_INT in crypto/md2/md2.h
# MD2_LONG	use 'long' instead of 'int' for MD2_INT in crypto/md2/md2.h
79 80 81 82 83 84
# IDEA_SHORT	use 'short' instead of 'int' for IDEA_INT in crypto/idea/idea.h
# IDEA_LONG	use 'long' instead of 'int' for IDEA_INT in crypto/idea/idea.h
# RC2_SHORT	use 'short' instead of 'int' for RC2_INT in crypto/rc2/rc2.h

# RC4_LONG	use 'long' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
85
# RC4_INDEX	define RC4_INDEX in crypto/rc4/rc4_locl.h.  This turns on
86
#		array lookups instead of pointer use.
87 88 89 90
# RC4_CHUNK	enables code that handles data aligned at long (natural CPU
#		word) boundary.
# RC4_CHUNK_LL	enables code that handles data aligned at long long boundary
#		(intended for 64-bit CPUs running 32-bit OS).
91
# BF_PTR	use 'pointer arithmatic' for Blowfish (unsafe on Alpha).
92
# BF_PTR2	intel specific version (generic version is more efficient).
93 94 95
#
# Following are set automatically by this script
#
96 97 98
# MD5_ASM	use some extra md5 assember,
# SHA1_ASM	use some extra sha1 assember, must define L_ENDIAN for x86
# RMD160_ASM	use some extra ripemd160 assember,
99 100 101
# SHA256_ASM	sha256_block is implemented in assembler
