INSTALLATION ON THE UNIX PLATFORM
---------------------------------
- [See INSTALL.W32 for instructions for compiling OpenSSL on Windows systems,
- and INSTALL.VMS for installing on OpenVMS systems.]
+ [Installation on DOS (with djgpp), Windows, MacOS (before MacOS X)
+ and NetWare is described in INSTALL.DJGPP, INSTALL.WIN, INSTALL.MacOS
+ and INSTALL.NW.
+
+ This document describes installation on the main supported operating
+ systems, currently the Unix family and OpenVMS.]
To install OpenSSL, you will need:
- * Perl 5
+ * make
+ * Perl 5 with core modules (please read README.PERL)
+ * The perl module Text::Template (please read README.PERL)
* an ANSI C compiler
- * a supported Unix operating system
+ * a development environment in form of development libraries and C
+ header files
+ * a supported operating system
+
+ For more details regarding specific platforms, there are these notes
+ available:
+
+ * NOTES.VMS
Quick Start
-----------
If you want to just get on with it, do:
- $ ./config
- $ make
- $ make test
- $ make install
+ on Unix:
+
+ $ ./config
+ $ make
+ $ make test
+ $ make install
+
+ on OpenVMS:
+
+ $ @config
+ $ mms
+ $ mms test
+ $ mms 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 (for
- historical reasons) /usr/local/ssl. If you want to install it anywhere else,
- run config like this:
+ 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 ('major'_'minor').
+
+ If you want to install it anywhere else, run config like this:
- $ ./config --prefix=/usr/local --openssldir=/usr/local/openssl
+ On Unix:
+
+ $ ./config --prefix=/opt/openssl --openssldir=/usr/local/ssl
+
+ On OpenVMS:
+
+ $ @config --prefix=PROGRAM:[INSTALLS] --openssldir=SYS$MANAGER:[OPENSSL]
Configuration Options
---------------------
- There are several options to ./config to customize the build:
+ There are several options to ./config (or ./Configure) to customize
+ the build:
+
+ --prefix=DIR The top of the installation directory tree. Defaults are:
+
+ Unix: /usr/local
+ OpenVMS: SYS$COMMON:[OPENSSL-'version']
+
+ --openssldir=DIR Directory for OpenSSL configuration files, and also the
+ default certificate and key store. Defaults are:
- --prefix=DIR Install in DIR/bin, DIR/lib, DIR/include/openssl.
- Configuration files used by OpenSSL will be in DIR/ssl
- or the directory specified by --openssldir.
+ Unix: PREFIX/ssl (PREFIX is given by --prefix)
+ OpenVMS: SYS$COMMON:[SSL]
- --openssldir=DIR Directory for OpenSSL files. If no prefix is specified,
- the library files and binaries are also installed there.
+ 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.
- rsaref Build with RSADSI's RSAREF toolkit (this assumes that
- librsaref.a is in the library search path).
+ 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-threads Don't try to build with support for multi-threaded
applications.
This will usually require additional system-dependent options!
See "Note on multi-threading" below.
+ no-zlib Don't try to build with support for zlib compression and
+ decompression.
+
+ 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. This is the default choice.
+
+ no-shared Don't try to create shared libraries.
+
+ shared In addition to the usual static libraries, create shared
+ libraries on platforms where it's supported. See "Note on
+ shared libraries" below.
+
no-asm Do not use assembler code.
- 386 Use the 80386 instruction set only (the default x86 code is
- more efficient, but requires at least a 486).
+ 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-sse2 Exclude SSE2 code pathes. 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 pathes upon application start-up,
+ but if you aim for wider "audience" running such kernel,
+ consider no-sse2. Both 386 and no-asm options above imply
+ no-sse2.
no-<cipher> Build without the specified cipher (bf, cast, des, dh, dsa,
hmac, md2, md5, mdc2, rc2, rc4, rc5, rsa, sha).
The crypto/<cipher> directory can be removed after running
"make depend".
- -Dxxx, -lxxx, -Lxxx, -fxxx, -Kxxx These system specific options will
+ -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.
1a. Configure OpenSSL for your operation system automatically:
- $ ./config [options]
+ $ ./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 it did not get it correct or you want to
- use a different compiler then go to step 1b. Otherwise go to step 2.
+ 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:
OpenSSL knows about a range of different operating system, hardware and
compiler combinations. To see the ones it knows about, run
- $ ./Configure
+ $ ./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
+ as the argument to Configure. For example, a "linux-elf" user would
run:
$ ./Configure linux-elf [options]
- If your system is not available, you will have to edit the Configure
- program and add the correct configuration for your system. The
- generic configurations "cc" or "gcc" should usually work.
+ 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 the file Makefile.ssl from Makefile.org and
+ Configure creates a build file ("Makefile" on Unix and "descrip.mms"
+ on OpenVMS) from a suitable template in Configurations, and
defines various macros in crypto/opensslconf.h (generated from
crypto/opensslconf.h.in).
- 2. Build OpenSSL by running:
+ 1c. Configure OpenSSL for building outside of the source tree.
- $ make
+ 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.
- This will build the OpenSSL libraries (libcrypto.a and libssl.a) and the
- OpenSSL binary ("openssl"). The libraries will be built in the top-level
- directory, and the binary will be in the "apps" directory.
+ Unix example:
- If "make" fails, please report the problem to <openssl-bugs@openssl.org>.
- Include the output of "./config -t" and the OpenSSL version
- number in your message.
+ $ mkdir /var/tmp/openssl-build
+ $ cd /var/tmp/openssl-build
+ $ /PATH/TO/OPENSSL/SOURCE/config [options]
- [If you encounter assembler error messages, try the "no-asm"
- configuration option as an immediate fix.]
+ or
- Compiling parts of OpenSSL with gcc and others with the system
- compiler will result in unresolved symbols on some systems.
+ $ /PATH/TO/OPENSSL/SOURCE/Configure [target] [options]
- 3. After a successful build, the libraries should be tested. Run:
+ OpenVMS example:
- $ make test
+ $ set default sys$login:
+ $ create/dir [.tmp.openssl-build]
+ $ set default [.tmp.openssl-build]
+ $ @[PATH.TO.OPENSSL.SOURCE]config {options}
- If a test fails, try removing any compiler optimization flags from
- the CFLAGS line in Makefile.ssl and run "make clean; make". Please
- send a bug report to <openssl-bugs@openssl.org>, including the
- output of "openssl version -a" and of the failed test.
+ or
- 4. If everything tests ok, install OpenSSL with
+ $ @[PATH.TO.OPENSSL.SOURCE]Configure {target} {options}
- $ make install
+ Paths can be relative just as well as absolute. Configure will
+ do its best to translate them to relative paths whenever possible.
- This will create the installation directory (if it does not exist) and
- then the following subdirectories:
+ 2. Build OpenSSL by running:
- certs Initially empty, this is the default location
- for certificate files.
- misc Various scripts.
- private Initially empty, this is the default location
- for private key files.
+ $ make # Unix
+ $ mms ! (or mmk) OpenVMS
- If you didn't choose a different installation prefix, the
- following additional subdirectories will be created:
+ 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.
- bin Contains the openssl binary and a few other
- utility programs.
- include/openssl Contains the header files needed if you want to
- compile programs with libcrypto or libssl.
- lib Contains the OpenSSL library files themselves.
+ 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 it is a problem 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). Include the output of "make
+ report" in your message. Please check out the request tracker. Maybe
+ the bug was already reported or has already been fixed.
- 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
+ [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.
- $ make INSTALL_PREFIX=/tmp/package-root install
+ 3. After a successful build, the libraries should be tested. Run:
- (or specify "--install_prefix=/tmp/package-root" as a configure
- option). The specified prefix will be prepended to all
- installation target filenames.
+ $ make test # Unix
+ $ mms test ! OpenVMS
+ 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:
- NOTE: The header files used to reside directly in the include
- directory, but have now been moved to include/openssl so that
- OpenSSL can co-exist with other libraries which use some of the
- same filenames. This means that applications that use OpenSSL
- should now use C preprocessor directives of the form
+ $ HARNESS_VERBOSE=yes make test # Unix
- #include <openssl/ssl.h>
+ $ DEFINE HARNESS_VERBOSE YES
+ $ mms test ! OpenVMS
- instead of "#include <ssl.h>", which was used with library versions
- up to OpenSSL 0.9.2b.
+ If you want to run just one or a few specific tests, you can use
+ the make variable TESTS to specify them, like this:
- If you install a new version of OpenSSL over an old library version,
- you should delete the old header files in the include directory.
+ $ make TESTS='test_rsa test_dsa' test # Unix
+ $ mms/macro="TESTS=test_rsa test_dsa" test ! OpenVMS
- Compatibility issues:
+ And of course, you can combine (Unix example shown):
+
+ $ HARNESS_VERBOSE=yes make TESTS='test_rsa test_dsa' test
- * COMPILING existing applications
+ You can find the list of available tests like this:
- To compile an application that uses old filenames -- e.g.
- "#include <ssl.h>" --, it will usually be enough to find
- the CFLAGS definition in the application's Makefile and
- add a C option such as
+ $ make list-tests # Unix
+ $ mms list-tests ! OpenVMS
- -I/usr/local/ssl/include/openssl
+ Have a look at the manual for the perl module Test::Harness to
+ see what other HARNESS_* variables there are.
- to it.
+ 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.
- But don't delete the existing -I option that points to
- the ..../include directory! Otherwise, OpenSSL header files
- could not #include each other.
+ Please send a bug report to <openssl-bugs@openssl.org>, and when
+ you do, please run the following and include the output in your
+ report:
- * WRITING applications
+ $ make report
- To write an application that is able to handle both the new
- and the old directory layout, so that it can still be compiled
- with library versions up to OpenSSL 0.9.2b without bothering
- the user, you can proceed as follows:
+ 4. If everything tests ok, install OpenSSL with
- - Always use the new filename of OpenSSL header files,
- e.g. #include <openssl/ssl.h>.
+ $ make install # Unix
+ $ mms install ! OpenVMS
+
+ 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,man3,man5,man7}
+ Contains the OpenSSL man-pages.
+ share/doc/openssl/html{man1,man3,man5,man7}
+ Contains the HTML rendition of the man-pages.
+
+ OpenVMS ('arch' is replaced with the architecture name, "Alpha"
+ or "ia64"):
+
+ [.EXE.'arch'] 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.'arch'] Contains the OpenSSL library files.
+ [.ENGINES.'arch']
+ Contains the OpenSSL dynamically loadable engines.
+ [.SYS$STARTUP] Contains startup, login and shutdown scripts.
+ These define appropriate logical names and
+ command symbols.
+
+
+ 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.
- - Create a directory "incl" that contains only a symbolic
- link named "openssl", which points to the "include" directory
- of OpenSSL.
- For example, your application's Makefile might contain the
- following rule, if OPENSSLDIR is a pathname (absolute or
- relative) of the directory where OpenSSL resides:
+ 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
- incl/openssl:
- -mkdir incl
- cd $(OPENSSLDIR) # Check whether the directory really exists
- -ln -s `cd $(OPENSSLDIR); pwd`/include incl/openssl
+ OpenSSL 1.1 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.
- You will have to add "incl/openssl" to the dependencies
- of those C files that include some OpenSSL header file.
+ 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.
- - Add "-Iincl" to your CFLAGS.
+ <TBA>
- With these additions, the OpenSSL header files will be available
- under both name variants if an old library version is used:
- Your application can reach them under names like <openssl/foo.h>,
- while the header files still are able to #include each other
- with names of the form <foo.h>.
+ Some APIs have changed as well. However, older APIs have been
+ preserved when possible.
Note on multi-threading
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
+ ------------------------
+
+ Shared libraries have certain caveats. Binary backward compatibility
+ can't be guaranteed before OpenSSL version 1.0. The only reason to
+ use them would be to conserve memory on systems where several programs
+ are using OpenSSL.
+
+ For some systems, the OpenSSL Configure script knows what is needed to
+ build shared libraries for libcrypto and libssl. On these systems,
+ the shared libraries are currently not created by default, but giving
+ the option "shared" will get them created. This method supports Makefile
+ targets for shared library creation, like linux-shared. Those targets
+ can currently be used on their own just as well, but this is expected
+ to change in future versions of OpenSSL.
+
+ 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 random seed.
+ Please check out the manual pages for RAND_add(), RAND_bytes(), RAND_egd(),
+ and the FAQ for more information.

-
-# When bringing the SSLeay distribution back from the evil intel world
-# of Windows NT, do the following to make it nice again under unix :-)
-# You don't normally need to run this.
-sh util/fixNT.sh # This only works for NT now - eay - 21-Jun-1996
-
-# If you have perl, and it is not in /usr/local/bin, you can run
-perl util/perlpath.pl /new/path
-# and this will fix the paths in all the scripts. DO NOT put
-# /new/path/perl, just /new/path. The build

-# 'applications' are easier to usr with the path fixed.
-
-# Edit crypto/cryptlib.h, tools/c_rehash, and Makefile.ssl
-# to set the install locations if you don't like
-# the default location of /usr/local/ssl
-# Do this by running
-perl util/ssldir.pl /new/ssl/home
-# if you have perl, or by hand if not.
-
-# If things have been stuffed up with the sym links, run

- SIXTEEN_BIT or EIGHT_BIT)
-Please remember that all these files are actually copies of the file with
-a .org extention. So if you change crypto/des/des.h, the next time
-you run Configure, it will be runover by a 'configured' version of
-crypto/des/des.org. So to make the changer the default, change the .org
-files. The reason these files have to be edited is because most of

-# The applicatons can be built by themselves, just don't define the
-# 'MONOLITH' flag. So to build the 'enc' program stand alone,
-gcc -O2 -Iinclude apps/enc.c apps/apps.c libcrypto.a
-
-# Other useful make options are
-make makefile.one
-# which generate a 'makefile.one' file which will build the complete

-
-# Have a look at running

-# There is actually a final way of building SSLeay.
-gcc -O2 -c -Icrypto -Iinclude crypto/crypto.c
-gcc -O2 -c -Issl -Iinclude ssl/ssl.c
-# and you now have the 2 libraries as single object files :-).
-# If you want to use the assember code for your particular platform
-# (DEC alpha/x86 are the main ones, the other assember is just the
-# output from gcc) you will need to link the assember with the above generated
-# object file and also do the above compile as
-gcc -O2 -DBN_ASM -c -Icrypto -Iinclude crypto/crypto.c
-
-This last option is probably the best way to go when porting to another
-platform or building shared libraries. It is not good for development so
-I don't normally use it.
-
-To build shared libararies under unix, have a look in shlib, basically
-you are on your own, but it is quite easy and all you have to do
-is compile 2 (or 3) files.
-
-For mult-threading, have a read of doc/threads.doc. Again it is quite
-easy and normally only requires some extra callbacks to be defined
-by the application.
-The examples for solaris and windows NT/95 are in the mt directory.
