Configuration Options
---------------------
- There are several options to ./config to customize the build:

--prefix=DIR Install in DIR/bin, DIR/lib, DIR/include/openssl.
Configuration files used by OpenSSL will be in DIR/ssl
This will usually require additional system-dependent options!
See "Note on multi-threading" below.
+ 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
OpenSSL binary ("openssl"). The libraries will be built in the top-level
directory, and the binary will be in the "apps" directory.
- If "make" fails, please report the problem to <openssl-bugs@openssl.org>
- (note that your message will be forwarded to a public mailing list).
- Include the output of "make report" in your message.
+ If "make" fails, look at the output. There may be reasons for

+ standard headers). If it is a problem with OpenSSL itself, please

+ message will be forwarded to a public mailing list). Include the
+ output of "make report" in your message.
[If you encounter assembler error messages, try the "no-asm"
configuration option as an immediate fix.]
$ make test
- 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 "make report".

you can still use "no-threads" to suppress an annoying warning message
from the Configure script.)

+ Note on shared libraries
+ ------------------------
+
+ 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.
