To install OpenSSL, you will need:
+ * make
* Perl 5
* an ANSI C compiler
+ * a development environment in form of development libraries and C
+ header files
* a supported Unix operating system
Quick Start
--openssldir=DIR Directory for OpenSSL files. If no prefix is specified,
the library files and binaries are also installed there.
- rsaref Build with RSADSI's RSAREF toolkit (this assumes that
- librsaref.a is in the library search path).
-
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
directory, and the binary will be in the "apps" directory.
If "make" fails, look at the output. There may be reasons for
- the failure that isn't a problem in OpenSSL itself (like missing
+ 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 <openssl-bugs@openssl.org> (note that your
message will be forwarded to a public mailing list). Include the
Note on shared libraries
------------------------
+ Shared library is currently an experimental feature. The only reason to
+ have them would be to conserve memory on systems where several program
+ are using OpenSSL. Binary backward compatibility can't be guaranteed
+ before OpenSSL version 1.0.
+
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
