# Options:
#
# --config      add the given configuration file, which will be read after
#               any "Configurations*" files that are found in the same
#               directory as this script.
# --openssldir  install OpenSSL in OPENSSLDIR (Default: DIR/ssl if the
#               --prefix option is given; /usr/local/ssl otherwise)
# --prefix      prefix for the OpenSSL include, lib and bin directories
#               (Default: the OPENSSLDIR directory)
#
# --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".
#
# --with-krb5-dir  Declare where Kerberos 5 lives.  The libraries are expected
#		to live in the subdirectory lib/ and the header files in
#		include/.  A value is required.
# --with-krb5-lib  Declare where the Kerberos 5 libraries live.  A value is
#		required.
#		(Default: KRB5_DIR/lib)
# --with-krb5-include  Declare where the Kerberos 5 header files live.  A
#		value is required.
#		(Default: KRB5_DIR/include)
# --with-krb5-flavor  Declare what flavor of Kerberos 5 is used.  Currently
#		supported values are "MIT" and "Heimdal".  A value is required.
#
# --test-sanity Make a number of sanity checks on the data in this file.
#               This is a debugging tool for OpenSSL developers.
#
# --cross-compile-prefix Add specified prefix to binutils components.
#
# 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.
# [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)
# [no-]shared	[don't] try to create shared libraries when supported.
# no-asm        do not use assembler
# no-dso        do not compile in any native shared-library methods. This
#               will ensure that all methods just return NULL.
# no-krb5       do not compile in any KRB5 library or code.
# [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.
# sctp          include SCTP support
# 386           generate 80386 code
# no-sse2	disables IA-32 SSE2 code, above option implies no-sse2
# no-<cipher>   build without specified algorithm (rsa, idea, rc5, ...)
# -<xxx> +<xxx> compiler options are passed through
#
# DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
#		provided to stack calls. Generates unique stack functions for
#		each possible stack type.
# 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
# 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
# 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
# RC2_LONG	use 'long' instead of 'int' for RC2_INT in crypto/rc2/rc2.h
# RC4_CHAR	use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# RC4_LONG	use 'long' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# RC4_INDEX	define RC4_INDEX in crypto/rc4/rc4_locl.h.  This turns on
#		array lookups instead of pointer use.
# 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).
# BF_PTR	use 'pointer arithmatic' for Blowfish (unsafe on Alpha).
# BF_PTR2	intel specific version (generic version is more efficient).
#
# Following are set automatically by this script
#
# 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,
# SHA256_ASM	sha256_block is implemented in assembler
# SHA512_ASM	sha512_block is implemented in assembler
# AES_ASM	ASE_[en|de]crypt is implemented in assembler

# Minimum warning options... any contributions to OpenSSL should at least get

# table of known configurations, read in from files
#
# The content of each entry can take one of two forms:
#
# - old style config-string, colon seperated fields with exactly the
#   following structure.:
#
#	$cc : $cflags : $unistd : $thread_cflag : $sys_id : $lflags : $bn_ops : $cpuid_obj : $bn_obj : $ec_obj : $des_obj : $aes_obj : $bf_obj : $md5_obj : $sha1_obj : $cast_obj : $rc4_obj : $rmd160_obj : $rc5_obj : $wp_obj : $cmll_obj : $modes_obj : $engines_obj : $perlasm_scheme : $dso_scheme : $shared_target : $shared_cflag : $shared_ldflag : $shared_extension : $ranlib : $arflags : $multilib

#   We use the stringtohash function - defined below - to combine with the

#
# - direct transfer of old style config string to hash table, using the names

# The configuration reader will do what it can to translate everything into
# new style config hash tables, including merging $target and debug-$target
# if they are similar enough.
#
# The configuration hashes can refer to templates in two different manners:
#
# - as part of the hash, one can have a key called 'inherit_from' that
#   indicate what other configuration hashes to inherit data from.
#   These are resolved recursively.
#
#   Inheritance works as a set of default values that can be overriden
#   by corresponding attribute values in the inheriting configuration.
#
#   If several configurations are given in the 'inherit_from' array, the
#   values of same attribute are concatenated with space separation.
#   With this, it's possible to have several smaller templates for
#   different configuration aspects that can be combined into a complete
#   configuration.
#
#   Example:
#
#	"foo" => {
#		template => 1,
#		haha => "haha",
#		hoho => "ho"
#	},
#	"bar" => {
#		template => 1,
#		hoho => "ho",
#		hehe => "hehe"
#	},
#	"laughter" => {
#		inherit_from => [ "foo", "bar" ],
#	}
#
#	The entry for "foo" will become as follows after processing:
#
#	"laughter" => {
#		haha => "haha",
#		hoho => "ho ho",
#		hehe => "hehe"
#	}
#
#   Note 1: any entry from the table can be used as a template.
#   Note 2: pure templates have the attribute 'template => 1' and cannot
#           be used as targets.
#
# - instead of a string, one can have a code block of the form
#   'sub { /* your code here */ }', where the arguments are the list of
#   inherited values for that key.  In fact, the concatenation of strings
#   is really done by using 'sub { join(" ",@_) }' on the list of inherited
#   values.
#
#   Example:
#
#	"foo" => {
#		template => 1,
#		haha => "ha ha",
#		hoho => "ho",
#		ignored => "This should not appear in the end result",
#	},
#	"bar" => {
#		template => 1,
#		haha => "ah",
#		hoho => "haho",
#		hehe => "hehe"
#	},
#	"laughter" => {
#		inherit_from => [ "foo", "bar" ],
#		hehe => sub { join(" ",(@_,"!!!")) },
#		ignored => "",
#	}
#
#	The entry for "foo" will become as follows after processing:
#
#	"laughter" => {
#		haha => "ha ha ah",
#		hoho => "ho haho",
#		hehe => "hehe !!!",
#		ignored => ""
#	}

You gave the option 'shared'.  Normally, that would give you shared libraries.
Unfortunately, the OpenSSL configuration doesn't include shared library support
for this platform yet, so it will pretend you gave the option 'no-shared'.  If
you can inform the developpers (openssl-dev\@openssl.org) how to support shared
libraries on this platform, they will at least look at it and try their best
(but please first make sure you have tried with a current version of OpenSSL).
