Configuration Options
---------------------
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
+ Don't use anything from the C header file "stdio.h" that
+ makes use of the "FILE" type. 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.
enable-tls1_3
TODO(TLS1.3): Make this enabled by default
Build support for TLS1.3. Note: This is a WIP feature and
- does not currently interoperate with other TLS1.3
- implementations! Use with caution!!
+ only a single draft version is supported. Implementations
+ of different draft versions will negotiate TLS 1.2 instead
+ of (draft) TLS 1.3. Use with caution!!
no-<prot>
Don't build support for negotiating the specified SSL/TLS
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, mdc2, ocb, poly1305,
- rc2, rc4, rmd160, scrypt, seed, siphash or whirlpool. The
- "ripemd" algorithm is deprecated and if used is synonymous
- with rmd160.
+ rc2, rc4, rmd160, scrypt, seed, siphash, sm3, sm4 or
+ whirlpool. The "ripemd" algorithm is deprecated and if used
+ is synonymous with rmd160.
-Dxxx, lxxx, -Lxxx, -Wl, -rpath, -R, -framework, -static
- These system specific options will be recocognised and
+ These system specific options will be recognised and
passed through to the compiler to allow you to define
preprocessor symbols, specify additional libraries, library
directories or other compiler options. It might be worth
passed through as they are to the compiler as well. Again,
consult your compiler documentation.
+ VAR=value
+ Assignment if environment variable for Configure. These
+ work just like normal environment variable assignments,
+ but are supported on all platforms and are confined to
+ the configuration scripts only. These assignments override
+ the corresponding value in the inherited environment, if
+ there is one.
+
+ reconf
+ reconfigure
+ Reconfigure from earlier data. This fetches the previous
+ command line options and environment from data saved in
+ "configdata.pm", and runs the configuration process again,
+ using these options and environment.
+ Note: NO other option is permitted together with "reconf".
+ This means that you also MUST use "./Configure" (or
+ what corresponds to that on non-Unix platforms) directly
+ to invoke this option.
+ Note: The original configuration saves away values for ALL
+ environment variables that were used, and if they weren't
+ defined, they are still saved away with information that
+ they weren't originally defined. This information takes
+ precedence over environment variables that are defined
+ when reconfiguring.
Installation in Detail
----------------------
compiler optimization flags from the CFLAGS line in Makefile and
run "make clean; make" or corresponding.
- Please send bug reports to <rt@openssl.org>.
+ To report a bug please open an issue on GitHub, at
+ https://github.com/openssl/openssl/issues.
