EOF# 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 its 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 Dont 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 isnt compiled.

no-hw do not compile support for any crypto hardware.

[no-]threads [dont] try to create a library that is suitable for

multithreaded applications (default is threads if we

know how to do it)

[no-]thread-pool

[dont] allow thread pool functionality

[no-]default-thread-pool

[dont] allow default thread pool functionality

[no-]shared [dont] try to create shared libraries when supported.

[no-]pic [dont] 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 [dont] 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 Dont 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 its 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 its 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,

SHA512_ASM sha512_block is implemented in assembler

AESASM 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.my gcc_devteam_warn qw(-DPEDANTIC -pedantic -Wno-long-long -DUNUSEDRESULT_DEBUG-Wall-Wmissing-declarations-Wextra-Wno-unused-parameter-Wno-missing-field-initializers-Wswitch-Wsign-compare-Wshadow-Wformat-Wno-type-limits-Wno-tautological-constant-out-of-range-compare-Wundef-Werror-Wmissing-prototypes-Wstrict-prototypes

Build up information for skipping certain directories depending on disabled

features, as well as setting up macros for disabled features.# This is a tentative database of directories to skip. Some entries may not

correspond to anything real, but thats ok, they will simply be ignored.

The actual processing of these entries is done in the build.info lookup

loop further down.

#

The key is a Unix formatted path in the source tree, the value is an index

into %disabled_info, so any existing path gets added to a corresponding

skipped entry in there with the list of skipped directories.

They all

return a CODE ref, which will return the intended value when evaluated.

Thus, whenever theres mention of a returned value, its about that

intended value.# Helper function to implement conditional value variants, with a default

plus additional values based on the value of $config{build_type}.

Arguments are given in hash table form:

#

picker(default Basic string: ,

debug debug,

release release)

#

When configuring with –debug, the resulting string will be

Basic string: debug, and when not, it will be Basic string: release

#

This can be used to create variants of sets of flags according to the

build type:

#

cflags picker(default -Wall,

debug -g -O0,

release -O3)

# sub picker {my %opts _;return sub { add(\(opts{default} || (),\)opts{$config{build_type}} || ())-(); } }# Helper function to combine several values of different types into one.

This is useful if you want to combine a string with the result of a

lazy function, such as:

#

cflags combine(-Wall, sub { $disabled{zlib} ? () : -DZLIB })

# sub combine {my stuff _;return sub { add(stuff)-(); } }# Helper function to implement conditional values depending on the value

of $disabled{threads}. Can be used as follows:

#

cflags combine(-Wall, threads(-pthread))

# sub threads {my flags _;return sub { add(\(disabled{threads} ? () : flags)-(); } }sub shared {my flags _;return sub { add(\)disabled{shared} ? () : flags)-(); } }our $add_called 0;

tokenize(\(line,\)separator)

$line is a line of text to split up into tokens

$separator [optional] is a regular expression that separates the tokens,

the default being spaces. Do not use quotes of any kind as separators,

that will give undefined results.

Returns a list of tokens.

#

Tokens are divided by separator (spaces by default). If the tokens include

the separators, they have to be quoted with single or double quotes.

Double quotes inside a double quoted token must be escaped. Escaping is done

with backslash.

Basically, the same quoting rules apply for and as in any

Unix shell.
