OPENSSL INSTALLATION
|
|
--------------------
|
|
|
|
This document describes installation on all supported operating
|
|
systems (the Linux/Unix family, OpenVMS and Windows)
|
|
|
|
To install OpenSSL, you will need:
|
|
|
|
* A make implementation
|
|
* Perl 5 with core modules (please read NOTES.PERL)
|
|
* The perl module Text::Template (please read NOTES.PERL)
|
|
* an ANSI C compiler
|
|
* a development environment in the form of development libraries and C
|
|
header files
|
|
* a supported operating system
|
|
|
|
For additional platform specific requirements, solutions to specific
|
|
issues and other details, please read one of these:
|
|
|
|
* NOTES.VMS (OpenVMS)
|
|
* NOTES.WIN (any supported Windows)
|
|
* NOTES.DJGPP (DOS platform with DJGPP)
|
|
|
|
Notational conventions in this document
|
|
---------------------------------------
|
|
|
|
Throughout this document, we use the following conventions in command
|
|
examples:
|
|
|
|
$ command Any line starting with a dollar sign
|
|
($) is a command line.
|
|
|
|
{ word1 | word2 | word3 } This denotes a mandatory choice, to be
|
|
replaced with one of the given words.
|
|
A simple example would be this:
|
|
|
|
$ echo { FOO | BAR | COOKIE }
|
|
|
|
which is to be understood as one of
|
|
these:
|
|
|
|
$ echo FOO
|
|
- or -
|
|
$ echo BAR
|
|
- or -
|
|
$ echo COOKIE
|
|
|
|
[ word1 | word2 | word3 ] Similar to { word1 | word2 | word3 }
|
|
except it's optional to give any of
|
|
those. In addition to the examples
|
|
above, this would also be valid:
|
|
|
|
$ echo
|
|
|
|
{{ target }} This denotes a mandatory word or
|
|
sequence of words of some sort. A
|
|
simple example would be this:
|
|
|
|
$ type {{ filename }}
|
|
|
|
which is to be understood to use the
|
|
command 'type' on some file name
|
|
determined by the user.
|
|
|
|
[[ options ]] Similar to {{ target }}, but is
|
|
optional.
|
|
|
|
Note that the notation assumes spaces around {, }, [, ], {{, }} and
|
|
[[, ]]. This is to differentiate from OpenVMS directory
|
|
specifications, which also use [ and ], but without spaces.
|
|
|
|
Quick Start
|
|
-----------
|
|
|
|
If you want to just get on with it, do:
|
|
|
|
on Unix:
|
|
|
|
$ ./config
|
|
$ make
|
|
$ make test
|
|
$ make install
|
|
|
|
on OpenVMS:
|
|
|
|
$ @config
|
|
$ mms
|
|
$ mms test
|
|
$ mms install
|
|
|
|
on Windows (only pick one of the targets for configuration):
|
|
|
|
$ perl Configure { VC-WIN32 | VC-WIN64A | VC-WIN64I | VC-CE }
|
|
$ nmake
|
|
$ nmake test
|
|
$ nmake install
|
|
|
|
If any of these steps fails, see section Installation in Detail below.
|
|
|
|
This will build and install OpenSSL in the default location, which is:
|
|
|
|
Unix: normal installation directories under /usr/local
|
|
OpenVMS: SYS$COMMON:[OPENSSL-'version'...], where 'version' is the
|
|
OpenSSL version number with underscores instead of periods.
|
|
Windows: C:\Program Files\OpenSSL or C:\Program Files (x86)\OpenSSL
|
|
|
|
If you want to install it anywhere else, run config like this:
|
|
|
|
On Unix:
|
|
|
|
$ ./config --prefix=/opt/openssl --openssldir=/usr/local/ssl
|
|
|
|
On OpenVMS:
|
|
|
|
$ @config --prefix=PROGRAM:[INSTALLS] --openssldir=SYS$MANAGER:[OPENSSL]
|
|
|
|
|
|
Configuration Options
|
|
---------------------
|
|
|
|
There are several options to ./config (or ./Configure) to customize
|
|
the build (note that for Windows, the defaults for --prefix and
|
|
--openssldir depend in what configuration is used and what Windows
|
|
implementation OpenSSL is built on. More notes on this in NOTES.WIN):
|
|
|
|
--api=x.y.z
|
|
Don't build with support for deprecated APIs below the
|
|
specified version number. For example "--api=1.1.0" will
|
|
remove support for all APIS that were deprecated in OpenSSL
|
|
version 1.1.0 or below.
|
|
|
|
--cross-compile-prefix=PREFIX
|
|
The PREFIX to include in front of commands for your
|
|
toolchain. It's likely to have to end with dash, e.g.
|
|
a-b-c- would invoke GNU compiler as a-b-c-gcc, etc.
|
|
Unfortunately cross-compiling is too case-specific to
|
|
put together one-size-fits-all instructions. You might
|
|
have to pass more flags or set up environment variables
|
|
to actually make it work. Android and iOS cases are
|
|
discussed in corresponding Configurations/10-main.cf
|
|
sections. But there are cases when this option alone is
|
|
sufficient. For example to build the mingw64 target on
|
|
Linux "--cross-compile-prefix=x86_64-w64-mingw32-"
|
|
works. Naturally provided that mingw packages are
|
|
installed. Today Debian and Ubuntu users have option to
|
|
install a number of prepackaged cross-compilers along
|
|
with corresponding run-time and development packages for
|
|
"alien" hardware. To give another example
|
|
"--cross-compile-prefix=mipsel-linux-gnu-" suffices
|
|
in such case. Needless to mention that you have to
|
|
invoke ./Configure, not ./config, and pass your target
|
|
name explicitly.
|
|
|
|
--debug
|
|
Build OpenSSL with debugging symbols.
|
|
|
|
--libdir=DIR
|
|
The name of the directory under the top of the installation
|
|
directory tree (see the --prefix option) where libraries will
|
|
be installed. By default this is "lib". Note that on Windows
|
|
only ".lib" files will be stored in this location. dll files
|
|
will always be installed to the "bin" directory.
|
|
|
|
--openssldir=DIR
|
|
Directory for OpenSSL configuration files, and also the
|
|
default certificate and key store. Defaults are:
|
|
|
|
Unix: /usr/local/ssl
|
|
Windows: C:\Program Files\Common Files\SSL
|
|
or C:\Program Files (x86)\Common Files\SSL
|
|
OpenVMS: SYS$COMMON:[OPENSSL-COMMON]
|
|
|
|
--prefix=DIR
|
|
The top of the installation directory tree. Defaults are:
|
|
|
|
Unix: /usr/local
|
|
Windows: C:\Program Files\OpenSSL
|
|
or C:\Program Files (x86)\OpenSSL
|
|
OpenVMS: SYS$COMMON:[OPENSSL-'version']
|
|
|
|
--release
|
|
Build OpenSSL without debugging symbols. This is the default.
|
|
|
|
--strict-warnings
|
|
This is a developer flag that switches on various compiler
|
|
options recommended for OpenSSL development. It only works
|
|
when using gcc or clang as the compiler. If you are
|
|
developing a patch for OpenSSL then it is recommended that
|
|
you use this option where possible.
|
|
|
|
--with-zlib-include=DIR
|
|
The directory for the location of the zlib include file. This
|
|
option is only necessary if enable-zlib (see below) is used
|
|
and the include file is not already on the system include
|
|
path.
|
|
|
|
--with-zlib-lib=LIB
|
|
On Unix: this is the directory containing the zlib library.
|
|
If not provided the system library path will be used.
|
|
On Windows: this is the filename of the zlib library (with or
|
|
without a path). This flag must be provided if the
|
|
zlib-dynamic option is not also used. If zlib-dynamic is used
|
|
then this flag is optional and a default value ("ZLIB1") is
|
|
used if not provided.
|
|
On VMS: this is the filename of the zlib library (with or
|
|
without a path). This flag is optional and if not provided
|
|
then "GNV$LIBZSHR", "GNV$LIBZSHR32" or "GNV$LIBZSHR64" is
|
|
used by default depending on the pointer size chosen.
|
|
|
|
no-afalgeng
|
|
Don't build the AFALG engine. This option will be forced if
|
|
on a platform that does not support AFALG.
|
|
|
|
enable-asan
|
|
Build with the Address sanitiser. This is a developer option
|
|
only. It may not work on all platforms and should never be
|
|
used in production environments. It will only work when used
|
|
with gcc or clang and should be used in conjunction with the
|
|
no-shared option.
|
|
|
|
no-asm
|
|
Do not use assembler code. On some platforms a small amount
|
|
of assembler code may still be used.
|
|
|
|
no-async
|
|
Do not build support for async operations.
|
|
|
|
no-autoalginit
|
|
Don't automatically load all supported ciphers and digests.
|
|
Typically OpenSSL will make available all of its supported
|
|
ciphers and digests. For a statically linked application this
|
|
may be undesirable if small executable size is an objective.
|
|
This only affects libcrypto. Ciphers and digests will have to
|
|
be loaded manually using EVP_add_cipher() and
|
|
EVP_add_digest() if this option is used. This option will
|
|
force a non-shared build.
|
|
|
|
no-autoerrinit
|
|
Don't automatically load all libcrypto/libssl error strings.
|
|
Typically OpenSSL will automatically load human readable
|
|
error strings. For a statically linked application this may
|
|
be undesirable if small executable size is an objective.
|
|
|
|
|
|
no-capieng
|
|
Don't build the CAPI engine. This option will be forced if
|
|
on a platform that does not support CAPI.
|
|
|
|
no-cms
|
|
Don't build support for CMS features
|
|
|
|
no-comp
|
|
Don't build support for SSL/TLS compression. If this option
|
|
is left enabled (the default), then compression will only
|
|
work if the zlib or zlib-dynamic options are also chosen.
|
|
|
|
enable-crypto-mdebug
|
|
Build support for debugging memory allocated via
|
|
OPENSSL_malloc() or OPENSSL_zalloc().
|
|
|
|
enable-crypto-mdebug-backtrace
|
|
As for crypto-mdebug, but additionally provide backtrace
|
|
information for allocated memory.
|
|
TO BE USED WITH CARE: this uses GNU C functionality, and
|
|
is therefore not usable for non-GNU config targets. If
|
|
your build complains about the use of '-rdynamic' or the
|
|
lack of header file execinfo.h, this option is not for you.
|
|
ALSO NOTE that even though execinfo.h is available on your
|
|
system (through Gnulib), the functions might just be stubs
|
|
that do nothing.
|
|
|
|
no-ct
|
|
Don't build support for Certificate Transparency.
|
|
|
|
no-deprecated
|
|
Don't build with support for any deprecated APIs. This is the
|
|
same as using "--api" and supplying the latest version
|
|
number.
|
|
|
|
no-dgram
|
|
Don't build support for datagram based BIOs. Selecting this
|
|
option will also force the disabling of DTLS.
|
|
|
|
no-dso
|
|
Don't build support for loading Dynamic Shared Objects.
|
|
|
|
no-dynamic-engine
|
|
Don't build the dynamically loaded engines. This only has an
|
|
effect in a "shared" build
|
|
|
|
no-ec
|
|
Don't build support for Elliptic Curves.
|
|
|
|
no-ec2m
|
|
Don't build support for binary Elliptic Curves
|
|
|
|
enable-ec_nistp_64_gcc_128
|
|
Enable support for optimised implementations of some commonly
|
|
used NIST elliptic curves. This is only supported on some
|
|
platforms.
|
|
|
|
enable-egd
|
|
Build support for gathering entropy from EGD (Entropy
|
|
Gathering Daemon).
|
|
|
|
no-engine
|
|
Don't build support for loading engines.
|
|
|
|
no-err
|
|
Don't compile in any error strings.
|
|
|
|
no-filenames
|
|
Don't compile in filename and line number information (e.g.
|
|
for errors and memory allocation).
|
|
|
|
enable-fuzz-libfuzzer, enable-fuzz-afl
|
|
Build with support for fuzzing using either libfuzzer or AFL.
|
|
These are developer options only. They may not work on all
|
|
platforms and should never be used in production environments.
|
|
See the file fuzz/README.md for further details.
|
|
|
|
no-gost
|
|
Don't build support for GOST based ciphersuites. Note that
|
|
if this feature is enabled then GOST ciphersuites are only
|
|
available if the GOST algorithms are also available through
|
|
loading an externally supplied engine.
|
|
|
|
enable-heartbeats
|
|
Build support for DTLS heartbeats.
|
|
|
|
no-hw-padlock
|
|
Don't build the padlock engine.
|
|
|
|
no-makedepend
|
|
Don't generate dependencies.
|
|
|
|
no-multiblock
|
|
Don't build support for writing multiple records in one
|
|
go in libssl (Note: this is a different capability to the
|
|
pipelining functionality).
|
|
|
|
no-nextprotoneg
|
|
Don't build support for the NPN TLS extension.
|
|
|
|
no-ocsp
|
|
Don't build support for OCSP.
|
|
|
|
no-pic
|
|
Don't build with support for Position Independent Code.
|
|
|
|
no-posix-io
|
|
Don't use POSIX IO capabilities.
|
|
|
|
no-psk
|
|
Don't build support for Pre-Shared Key based ciphersuites.
|
|
|
|
no-rdrand
|
|
Don't use hardware RDRAND capabilities.
|
|
|
|
no-rfc3779
|
|
Don't build support for RFC3779 ("X.509 Extensions for IP
|
|
Addresses and AS Identifiers")
|
|
|
|
sctp
|
|
Build support for SCTP
|
|
|
|
no-shared
|
|
Do not create shared libraries, only static ones. See "Note
|
|
on shared libraries" below.
|
|
|
|
no-sock
|
|
Don't build support for socket BIOs
|
|
|
|
no-srp
|
|
Don't build support for SRP or SRP based ciphersuites.
|
|
|
|
no-srtp
|
|
Don't build SRTP support
|
|
|
|
no-sse2
|
|
Exclude SSE2 code paths. Normally SSE2 extension is
|
|
detected at run-time, but the decision whether or not the
|
|
machine code will be executed is taken solely on CPU
|
|
capability vector. This means that if you happen to run OS
|
|
kernel which does not support SSE2 extension on Intel P4
|
|
processor, then your application might be exposed to
|
|
"illegal instruction" exception. There might be a way
|
|
to enable support in kernel, e.g. FreeBSD kernel can be
|
|
compiled with CPU_ENABLE_SSE, and there is a way to
|
|
disengage SSE2 code paths upon application start-up,
|
|
but if you aim for wider "audience" running such kernel,
|
|
consider no-sse2. Both the 386 and no-asm options imply
|
|
no-sse2.
|
|
|
|
enable-ssl-trace
|
|
Build with the SSL Trace capabilities (adds the "-trace"
|
|
option to s_client and s_server).
|
|
|
|
no-static-engine
|
|
Don't build the statically linked engines. This only
|
|
has an impact when not built "shared".
|
|
|
|
no-stdio
|
|
Don't use any C "stdio" features. Only libcrypto and libssl
|
|
can be built in this way. Using this option will suppress
|
|
building the command line applications. Additionally since
|
|
the OpenSSL tests also use the command line applications the
|
|
tests will also be skipped.
|
|
|
|
no-threads
|
|
Don't try to build with support for multi-threaded
|
|
applications.
|
|
|
|
threads
|
|
Build with support for multi-threaded applications. Most
|
|
platforms will enable this by default. However if on a
|
|
platform where this is not the case then this will usually
|
|
require additional system-dependent options! See "Note on
|
|
multi-threading" below.
|
|
|
|
no-ts
|
|
Don't build Time Stamping Authority support.
|
|
|
|
enable-ubsan
|
|
Build with the Undefined Behaviour sanitiser. This is a
|
|
developer option only. It may not work on all platforms and
|
|
should never be used in production environments. It will only
|
|
work when used with gcc or clang and should be used in
|
|
conjunction with the "-DPEDANTIC" option (or the
|
|
--strict-warnings option).
|
|
|
|
no-ui
|
|
Don't build with the "UI" capability (i.e. the set of
|
|
features enabling text based prompts).
|
|
|
|
enable-unit-test
|
|
Enable additional unit test APIs. This should not typically
|
|
be used in production deployments.
|
|
|
|
enable-weak-ssl-ciphers
|
|
Build support for SSL/TLS ciphers that are considered "weak"
|
|
(e.g. RC4 based ciphersuites).
|
|
|
|
zlib
|
|
Build with support for zlib compression/decompression.
|
|
|
|
zlib-dynamic
|
|
Like "zlib", but has OpenSSL load the zlib library
|
|
dynamically when needed. This is only supported on systems
|
|
where loading of shared libraries is supported.
|
|
|
|
386
|
|
On Intel hardware, use the 80386 instruction set only
|
|
(the default x86 code is more efficient, but requires at
|
|
least a 486). Note: Use compiler flags for any other CPU
|
|
specific configuration, e.g. "-m32" to build x86 code on
|
|
an x64 system.
|
|
|
|
no-<prot>
|
|
Don't build support for negotiating the specified SSL/TLS
|
|
protocol (one of ssl, ssl3, tls, tls1, tls1_1, tls1_2, dtls,
|
|
dtls1 or dtls1_2). If "no-tls" is selected then all of tls1,
|
|
tls1_1 and tls1_2 are disabled. Similarly "no-dtls" will
|
|
disable dtls1 and dtls1_2. The "no-ssl" option is synonymous
|
|
with "no-ssl3". Note this only affects version negotiation.
|
|
OpenSSL will still provide the methods for applications to
|
|
explicitly select the individual protocol versions.
|
|
|
|
no-<prot>-method
|
|
As for no-<prot> but in addition do not build the methods for
|
|
applications to explicitly select individual protocol
|
|
versions.
|
|
|
|
enable-<alg>
|
|
Build with support for the specified algorithm, where <alg>
|
|
is one of: md2 or rc5.
|
|
|
|
no-<alg>
|
|
Build without support for the specified algorithm, where
|
|
<alg> is one of: bf, blake2, camellia, cast, chacha, cmac,
|
|
des, dh, dsa, ecdh, ecdsa, idea, md4, md5, mdc2, ocb,
|
|
ploy1305, rc2, rc4, rmd160, scrypt, seed or whirlpool. The
|
|
"ripemd" algorithm is deprecated and if used is synonymous
|
|
with rmd160.
|
|
|
|
-Dxxx, -lxxx, -Lxxx, -fxxx, -mXXX, -Kxxx
|
|
These system specific options will be passed through to the
|
|
compiler to allow you to define preprocessor symbols, specify
|
|
additional libraries, library directories or other compiler
|
|
options.
|
|
|
|
|
|
Installation in Detail
|
|
----------------------
|
|
|
|
1a. Configure OpenSSL for your operation system automatically:
|
|
|
|
NOTE: This is not available on Windows.
|
|
|
|
$ ./config [[ options ]] # Unix
|
|
|
|
or
|
|
|
|
$ @config [[ options ]] ! OpenVMS
|
|
|
|
For the remainder of this text, the Unix form will be used in all
|
|
examples, please use the appropriate form for your platform.
|
|
|
|
This guesses at your operating system (and compiler, if necessary) and
|
|
configures OpenSSL based on this guess. Run ./config -t to see
|
|
if it guessed correctly. If you want to use a different compiler, you
|
|
are cross-compiling for another platform, or the ./config guess was
|
|
wrong for other reasons, go to step 1b. Otherwise go to step 2.
|
|
|
|
On some systems, you can include debugging information as follows:
|
|
|
|
$ ./config -d [[ options ]]
|
|
|
|
1b. Configure OpenSSL for your operating system manually
|
|
|
|
OpenSSL knows about a range of different operating system, hardware and
|
|
compiler combinations. To see the ones it knows about, run
|
|
|
|
$ ./Configure # Unix
|
|
|
|
or
|
|
|
|
$ perl Configure # All other platforms
|
|
|
|
For the remainder of this text, the Unix form will be used in all
|
|
examples, please use the appropriate form for your platform.
|
|
|
|
Pick a suitable name from the list that matches your system. For most
|
|
operating systems there is a choice between using "cc" or "gcc". When
|
|
you have identified your system (and if necessary compiler) use this name
|
|
as the argument to Configure. For example, a "linux-elf" user would
|
|
run:
|
|
|
|
$ ./Configure linux-elf [[ options ]]
|
|
|
|
If your system isn't listed, you will have to create a configuration
|
|
file named Configurations/{{ something }}.conf and add the correct
|
|
configuration for your system. See the available configs as examples
|
|
and read Configurations/README and Configurations/README.design for
|
|
more information.
|
|
|
|
The generic configurations "cc" or "gcc" should usually work on 32 bit
|
|
Unix-like systems.
|
|
|
|
Configure creates a build file ("Makefile" on Unix, "makefile" on Windows
|
|
and "descrip.mms" on OpenVMS) from a suitable template in Configurations,
|
|
and defines various macros in include/openssl/opensslconf.h (generated from
|
|
include/openssl/opensslconf.h.in).
|
|
|
|
1c. Configure OpenSSL for building outside of the source tree.
|
|
|
|
OpenSSL can be configured to build in a build directory separate from
|
|
the directory with the source code. It's done by placing yourself in
|
|
some other directory and invoking the configuration commands from
|
|
there.
|
|
|
|
Unix example:
|
|
|
|
$ mkdir /var/tmp/openssl-build
|
|
$ cd /var/tmp/openssl-build
|
|
$ /PATH/TO/OPENSSL/SOURCE/config [[ options ]]
|
|
|
|
or
|
|
|
|
$ /PATH/TO/OPENSSL/SOURCE/Configure {{ target }} [[ options ]]
|
|
|
|
OpenVMS example:
|
|
|
|
$ set default sys$login:
|
|
$ create/dir [.tmp.openssl-build]
|
|
$ set default [.tmp.openssl-build]
|
|
$ @[PATH.TO.OPENSSL.SOURCE]config [[ options ]]
|
|
|
|
or
|
|
|
|
$ @[PATH.TO.OPENSSL.SOURCE]Configure {{ target }} [[ options ]]
|
|
|
|
Windows example:
|
|
|
|
$ C:
|
|
$ mkdir \temp-openssl
|
|
$ cd \temp-openssl
|
|
$ perl d:\PATH\TO\OPENSSL\SOURCE\Configure {{ target }} [[ options ]]
|
|
|
|
Paths can be relative just as well as absolute. Configure will
|
|
do its best to translate them to relative paths whenever possible.
|
|
|
|
2. Build OpenSSL by running:
|
|
|
|
$ make # Unix
|
|
$ mms ! (or mmk) OpenVMS
|
|
$ nmake # Windows
|
|
|
|
This will build the OpenSSL libraries (libcrypto.a and libssl.a on
|
|
Unix, corresponding on other platforms) and the OpenSSL binary
|
|
("openssl"). The libraries will be built in the top-level directory,
|
|
and the binary will be in the "apps" subdirectory.
|
|
|
|
If the build fails, look at the output. There may be reasons for
|
|
the failure that aren't problems in OpenSSL itself (like missing
|
|
standard headers). If you are having problems you can get help by
|
|
sending an email to the openssl-users email list (see
|
|
https://www.openssl.org/community/mailinglists.html for details). If it
|
|
is a bug with OpenSSL itself, please report the problem to
|
|
<rt@openssl.org> (note that your message will be recorded in the request
|
|
tracker publicly readable at
|
|
https://www.openssl.org/community/index.html#bugs and will be
|
|
forwarded to a public mailing list). Please check out the request
|
|
tracker. Maybe the bug was already reported or has already been
|
|
fixed.
|
|
|
|
(If you encounter assembler error messages, try the "no-asm"
|
|
configuration option as an immediate fix.)
|
|
|
|
Compiling parts of OpenSSL with gcc and others with the system
|
|
compiler will result in unresolved symbols on some systems.
|
|
|
|
3. After a successful build, the libraries should be tested. Run:
|
|
|
|
$ make test # Unix
|
|
$ mms test ! OpenVMS
|
|
$ nmake test # Windows
|
|
|
|
NOTE: you MUST run the tests from an unprivileged account (or
|
|
disable your privileges temporarily if your platform allows it).
|
|
|
|
If some tests fail, look at the output. There may be reasons for
|
|
the failure that isn't a problem in OpenSSL itself (like a
|
|
malfunction with Perl). You may want increased verbosity, that
|
|
can be accomplished like this:
|
|
|
|
$ make VERBOSE=1 test # Unix
|
|
|
|
$ mms /macro=(VERBOSE=1) test ! OpenVMS
|
|
|
|
$ nmake VERBOSE=1 test # Windows
|
|
|
|
If you want to run just one or a few specific tests, you can use
|
|
the make variable TESTS to specify them, like this:
|
|
|
|
$ make TESTS='test_rsa test_dsa' test # Unix
|
|
$ mms/macro="TESTS=test_rsa test_dsa" test ! OpenVMS
|
|
$ nmake TESTS='test_rsa test_dsa' test # Windows
|
|
|
|
And of course, you can combine (Unix example shown):
|
|
|
|
$ make VERBOSE=1 TESTS='test_rsa test_dsa' test
|
|
|
|
You can find the list of available tests like this:
|
|
|
|
$ make list-tests # Unix
|
|
$ mms list-tests ! OpenVMS
|
|
$ nmake list-tests # Windows
|
|
|
|
Have a look at the manual for the perl module Test::Harness to
|
|
see what other HARNESS_* variables there are.
|
|
|
|
If you find a problem with OpenSSL itself, try removing any
|
|
compiler optimization flags from the CFLAGS line in Makefile and
|
|
run "make clean; make" or corresponding.
|
|
|
|
Please send bug reports to <rt@openssl.org>.
|
|
|
|
4. If everything tests ok, install OpenSSL with
|
|
|
|
$ make install # Unix
|
|
$ mms install ! OpenVMS
|
|
$ nmake install # Windows
|
|
|
|
This will install all the software components in this directory
|
|
tree under PREFIX (the directory given with --prefix or its
|
|
default):
|
|
|
|
Unix:
|
|
|
|
bin/ Contains the openssl binary and a few other
|
|
utility scripts.
|
|
include/openssl
|
|
Contains the header files needed if you want
|
|
to build your own programs that use libcrypto
|
|
or libssl.
|
|
lib Contains the OpenSSL library files.
|
|
lib/engines Contains the OpenSSL dynamically loadable engines.
|
|
|
|
share/man/man1 Contains the OpenSSL command line man-pages.
|
|
share/man/man3 Contains the OpenSSL library calls man-pages.
|
|
share/man/man5 Contains the OpenSSL configuration format man-pages.
|
|

|
|
share/doc/openssl/html/man5
|
|
share/doc/openssl/html/man7
|
|
Contains the HTML rendition of the man-pages.
|
|
|
|
OpenVMS ('arch' is replaced with the architecture name, "Alpha"
|
|
or "ia64", 'sover' is replaced with the shared library version
|
|
(0101 for 1.1), and 'pz' is replaced with the pointer size
|
|
OpenSSL was built with):
|
|
|
|
[.EXE.'arch'] Contains the openssl binary.
|
|
[.EXE] Contains a few utility scripts.
|
|
[.include.openssl]
|
|
Contains the header files needed if you want
|
|
to build your own programs that use libcrypto
|
|
or libssl.
|
|
[.LIB.'arch'] Contains the OpenSSL library files.
|
|
[.ENGINES'sover''pz'.'arch']
|
|
Contains the OpenSSL dynamically loadable engines.
|
|
[.SYS$STARTUP] Contains startup, login and shutdown scripts.
|
|
These define appropriate logical names and
|
|
command symbols.
|
|
[.SYSTEST] Contains the installation verification procedure.
|
|
[.HTML] Contains the HTML rendition of the manual pages.
|
|
|
|
|
|
Additionally, install will add the following directories under
|
|
OPENSSLDIR (the directory given with --openssldir or its default)
|
|
for you convenience:
|
|
|
|
certs Initially empty, this is the default location
|
|
for certificate files.
|
|
private Initially empty, this is the default location
|
|
for private key files.
|
|
misc Various scripts.
|
|
|
|
Package builders who want to configure the library for standard
|
|
locations, but have the package installed somewhere else so that
|
|
it can easily be packaged, can use
|
|
|
|
$ make DESTDIR=/tmp/package-root install # Unix
|
|
$ mms/macro="DESTDIR=TMP:[PACKAGE-ROOT]" install ! OpenVMS
|
|
|
|
The specified destination directory will be prepended to all
|
|
installation target paths.
|
|
|
|
Compatibility issues with previous OpenSSL versions:
|
|
|
|
* COMPILING existing applications
|
|
|
|
OpenSSL 1.1.0 hides a number of structures that were previously
|
|
open. This includes all internal libssl structures and a number
|
|
of EVP types. Accessor functions have been added to allow
|
|
controlled access to the structures' data.
|
|
|
|
This means that some software needs to be rewritten to adapt to
|
|
the new ways of doing things. This often amounts to allocating
|
|
an instance of a structure explicitly where you could previously
|
|
allocate them on the stack as automatic variables, and using the
|
|
provided accessor functions where you would previously access a
|
|
structure's field directly.
|
|
|
|
Some APIs have changed as well. However, older APIs have been
|
|
preserved when possible.
|
|
|
|
Environment Variables
|
|
---------------------
|
|
|
|
A number of environment variables can be used to provide additional control
|
|
over the build process. Typically these should be defined prior to running
|
|
config or Configure. Not all environment variables are relevant to all
|
|
platforms.
|
|
|
|
AR
|
|
The name of the ar executable to use.
|
|
|
|
CC
|
|
The compiler to use. Configure will attempt to pick a default
|
|
compiler for your platform but this choice can be overridden
|
|
using this variable. Set it to the compiler executable you wish
|
|
to use, e.g. "gcc" or "clang".
|
|
|
|
CROSS_COMPILE
|
|
This environment variable has the same meaning as for the
|
|
"--cross-compile-prefix" Configure flag described above. If both
|
|
are set then the Configure flag takes precedence.
|
|
|
|
NM
|
|
The name of the nm executable to use.
|
|
|
|
OPENSSL_LOCAL_CONFIG_DIR
|
|
OpenSSL comes with a database of information about how it
|
|
should be built on different platforms. This information is
|
|
held in ".conf" files in the Configurations directory. See the
|
|
file Configurations/README for further information about the
|
|
format of ".conf" files. As well as the standard ".conf" files
|
|
it is possible to create your own ".conf" files and store them
|
|
locally, outside the OpenSSL source tree. This environment
|
|
variable can be set to the directory where these files are held.
|
|
|
|
PERL
|
|
The name of the Perl executable to use when building OpenSSL.
|
|
|
|
HASHBANGPERL
|
|
The command string for the Perl executable to insert in the
|
|
#! line of perl scripts that will be publically installed.
|
|
Default: /usr/bin/env perl
|
|
Note: the value of this variable is added to the same scripts
|
|
on all platforms, but it's only relevant on Unix-like platforms.
|
|
|
|
RC
|
|
The name of the rc executable to use. The default will be as
|
|
defined for the target platform in the ".conf" file. If not
|
|
defined then "windres" will be used. The WINDRES environment
|
|
variable is synonymous to this. If both are defined then RC
|
|
takes precedence.
|
|
|
|
RANLIB
|
|
The name of the ranlib executable to use.
|
|
|
|
WINDRES
|
|
See RC.
|
|
|
|
Makefile targets
|
|
----------------
|
|
|
|
The Configure script generates a Makefile in a format relevant to the specific
|
|
platform. The Makefiles provide a number of targets that can be used. Not all
|
|
targets may be available on all platforms. Only the most common targets are
|
|
described here. Examine the Makefiles themselves for the full list.
|
|
|
|
all
|
|
The default target to build all the software components.
|
|
|
|
clean
|
|
Remove all build artefacts and return the directory to a "clean"
|
|
state.
|
|
|
|
depend
|
|
Rebuild the dependencies in the Makefiles. This is a legacy
|
|
option that no longer needs to be used in OpenSSL 1.1.0.
|
|
|
|
install
|
|
Install all OpenSSL components.
|
|
|
|
install_sw
|
|
Only install the OpenSSL software components.
|
|
|
|
install_docs
|
|
Only install the OpenSSL documentation components.
|
|
|
|
install_man_docs
|
|
Only install the OpenSSL man pages (Unix only).
|
|
|
|
install_html_docs
|
|
Only install the OpenSSL html documentation.
|
|
|
|
list-tests
|
|
Prints a list of all the self test names.
|
|
|
|
test
|
|
Build and run the OpenSSL self tests.
|
|
|
|
uninstall
|
|
Uninstall all OpenSSL components.
|
|
|
|
update
|
|
This is a developer option. If you are developing a patch for
|
|
OpenSSL you may need to use this if you want to update
|
|
automatically generated files; add new error codes or add new
|
|
(or change the visibility of) public API functions. (Unix only).
|
|
|
|
Note on multi-threading
|
|
-----------------------
|
|
|
|
For some systems, the OpenSSL Configure script knows what compiler options
|
|
are needed to generate a library that is suitable for multi-threaded
|
|
applications. On these systems, support for multi-threading is enabled
|
|
by default; use the "no-threads" option to disable (this should never be
|
|
necessary).
|
|
|
|
On other systems, to enable support for multi-threading, you will have
|
|
to specify at least two options: "threads", and a system-dependent option.
|
|
(The latter is "-D_REENTRANT" on various systems.) The default in this
|
|
case, obviously, is not to include support for multi-threading (but
|
|
you can still use "no-threads" to suppress an annoying warning message
|
|
from the Configure script.)
|
|
|
|
OpenSSL provides built-in support for two threading models: pthreads (found on
|
|
most UNIX/Linux systems), and Windows threads. No other threading models are
|
|
supported. If your platform does not provide pthreads or Windows threads then
|
|
you should Configure with the "no-threads" option.
|
|
|
|
Note on shared libraries
|
|
------------------------
|
|
|
|
For most systems the OpenSSL Configure script knows what is needed to
|
|
build shared libraries for libcrypto and libssl. On these systems
|
|
the shared libraries will be created by default. This can be suppressed and
|
|
only static libraries created by using the "no-shared" option. On systems
|
|
where OpenSSL does not know how to build shared libraries the "no-shared"
|
|
option will be forced and only static libraries will be created.
|
|
|
|
Note on random number generation
|
|
--------------------------------
|
|
|
|
Availability of cryptographically secure random numbers is required for
|
|
secret key generation. OpenSSL provides several options to seed the
|
|
internal PRNG. If not properly seeded, the internal PRNG will refuse
|
|
to deliver random bytes and a "PRNG not seeded error" will occur.
|
|
On systems without /dev/urandom (or similar) device, it may be necessary
|
|
to install additional support software to obtain a random seed.
|
|
Please check out the manual pages for RAND_add(), RAND_bytes(), RAND_egd(),
|
|
and the FAQ for more information.
