sslscan @1.8.2_3 fails build Undefined symbols for architecture x86_64: "_SSLv2_client_method"

[udbraumann]

While upgrading sslscan from 1.8.2_2 to 1.8.2_3 on 10.6.8 I suddenly run into this error:

...
:info:build Undefined symbols for architecture x86_64:
:info:build   "_SSLv2_client_method", referenced from:
:info:build       _testCipher in cc0c6wcU.o
:info:build       _defaultCipher in cc0c6wcU.o
:info:build       _testHost in cc0c6wcU.o
:info:build       _main in cc0c6wcU.o
:info:build ld: symbol(s) not found for architecture x86_64
:info:build collect2: ld returned 1 exit status
:info:build make: *** [all] Error 1
...

Any ideas?

As I suddenly notice, the problem is apparently caused by a change in openssl. Starting from version 1.0.2.g SSLv2 is turned off, see ​https://www.openssl.org/news/cl102.txt:

SSLv2 is by default disabled at build-time. Builds that are not
configured with "enable-ssl2" will not support SSLv2.

That would mean, sslscan cannot be build anymore, unless openssl is being configured with "enable-ssl2".

Please do not Cc nomaintainer@… because it is not a valid email address.

We should upgrade sslscan to a new version that does not require SSLv2, if one exists, or report the problem to the developers if it does not.

The homepage listed in the port no longer exists. Looks like a github fork has sprung up: ​https://github.com/rbsec/sslscan

Does the problem persist with version 2.0.16?

The latest sslscan is building on 10.6 buildbots, and is building against OpenSSL 3. Closing this ticket as resolved.
