# 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.
# --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)
# --banner=".." Output specified text instead of default completion banner
#
# -w Don't wait after showing a Configure warning
#
# --cross-compile-prefix Add specified prefix to binutils components.
#
# --api One of 0.9.8, 1.0.0, 1.0.1, 1.0.2, 1.1.0, 1.1.1, or 3.0
# Define the public APIs as they were for that version
# including patch releases. If 'no-deprecated' is also
# given, do not compile support for interfaces deprecated
# up to and including the specified OpenSSL version.
#
# 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-]thread-pool
# [don't] allow thread pool functionality
# [no-]default-thread-pool
# [don't] allow default thread pool functionality
# [no-]shared [don't] try to create shared libraries when supported.
# [no-]pic [don't] try to build position independent code when supported.
# If disabled, it also disables shared and dynamic-engine.
# no-asm do not use assembler
# no-egd do not compile support for the entropy-gathering daemon APIs
# [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 at run-time by the OpenSSL library.
# sctp include SCTP support
# no-quic disable QUIC support
# no-uplink Don't build support for UPLINK interface.
# enable-weak-ssl-ciphers
# Enable weak ciphers that are disabled by default.
# 386 generate 80386 code in assembly modules
# no-sse2 disables IA-32 SSE2 code in assembly modules, the above
# mentioned '386' option implies this one
# no-<cipher> build without specified algorithm (dsa, idea, rc5, ...)
# -<xxx> +<xxx> All options which are unknown to the 'Configure' script are
# /<xxx> passed through to the compiler. Unix-style options beginning
# with a '-' or '+' are recognized, as well as Windows-style
# options beginning with a '/'. If the option contains arguments
# separated by spaces, then the URL-style notation %20 can be
# used for the space character in order to avoid having to quote
# the option. For example, -opt%20arg gets expanded to -opt arg.
# In fact, any ASCII character can be encoded as %xx using its
# hexadecimal encoding.
# -static while -static is also a pass-through compiler option (and
# as such is limited to environments where it's actually
# meaningful), it triggers a number configuration options,
# namely no-pic, no-shared and no-threads. It is
# argued that the only reason to produce statically linked
# binaries (and in context it means executables linked with
# -static flag, and not just executables linked with static
# libcrypto.a) is to eliminate dependency on specific run-time,
# a.k.a. libc version. The mentioned config options are meant
# to achieve just that. Unfortunately on Linux it's impossible
# to eliminate the dependency completely for openssl executable
# because of getaddrinfo and gethostbyname calls, which can
# invoke dynamically loadable library facility anyway to meet
# the lookup requests. For this reason on Linux statically
# linked openssl executable has rather debugging value than
# production quality.
#
# BN_LLONG use the type 'long long' in crypto/bn/bn.h
# RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# Following are set automatically by this script
#
# MD5_ASM use some extra md5 assembler,
# SHA1_ASM use some extra sha1 assembler, must define L_ENDIAN for x86
# RMD160_ASM use some extra ripemd160 assembler,
# SHA256_ASM sha256_block is implemented in assembler
# SHA512_ASM sha512_block is implemented in assembler
# AES_ASM AES_[en|de]crypt is implemented in assembler
# Minimum warning options... any contributions to OpenSSL should at least
# get past these. Note that we only use these with C compilers, not with
# C++ compilers.
# -DPEDANTIC complements -pedantic and is meant to mask code that
# is not strictly standard-compliant and/or implementation-specific,
# e.g. inline assembly, disregards to alignment requirements, such
# that -pedantic would complain about. Incidentally -DPEDANTIC has
# to be used even in sanitized builds, because sanitizer too is
# supposed to and does take notice of non-standard behaviour. Then
# -pedantic with pre-C9x compiler would also complain about 'long
# long' not being supported. As 64-bit algorithms are common now,
# it grew impossible to resolve this without sizeable additional
# code, so we just tell compiler to be pedantic about everything
# but 'long long' type.
