To install OpenSSL, you will need:
* Perl 5 with core modules (please read README.PERL)
* The perl module Text::Template (please read README.PERL)
* an ANSI C compiler
- * a development environment in form of development libraries and C
+ * a development environment in the form of development libraries and C
header files
* a supported operating system
There are several options to ./config (or ./Configure) to customize
the build:
- --prefix=DIR The top of the installation directory tree. Defaults are:
+ --prefix=DIR The top of the installation directory tree. Defaults are:
- Unix: /usr/local
- OpenVMS: SYS$COMMON:[OPENSSL-'version']
+ Unix: /usr/local
+ OpenVMS: SYS$COMMON:[OPENSSL-'version']
--openssldir=DIR Directory for OpenSSL configuration files, and also the
- default certificate and key store. Defaults are:
-
- Unix: PREFIX/ssl (PREFIX is given by --prefix)
- OpenVMS: SYS$COMMON:[SSL]
-
- 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.
-
- 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.
-
- threads 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 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, -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.

+
+ Unix: PREFIX/ssl (PREFIX is given by --prefix)
+ OpenVMS: SYS$COMMON:[SSL]
+
+ --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.
+
+ no-deprecated Don't build with support for any deprecated APIs. This is the
+ same as using "--api" and supplying the latest version
+ number.
