Description Eugene Grosbein freebsd_committer 2018-03-30 11:38:44 UTC
--- ab ---
ab.o: In function `main':
ab.c:(.text+0x88a): undefined reference to `SSLv2_client_method'
cc: error: linker command failed with exit code 1 (use -v to see invocation)
*** [ab] Error code 1

Here is the scenario:

1. FreeBSD 11.1 user has security/openssl installed like openssl-1.0.x compiled with default OPTIONS that include SSLv2 knob enabled.
2. User has DEFAULT_VERSIONS+=ssl=openssl in the /etc/make.conf
3. User tries to build www/apache24 port verion 2.4.33 and build fails with messages quoted above.

ktrace(1) shows that linker does not even try to use libssl.so installed by port but links "ab" with base /usr/lib/libssl.so that has no SSLv2_client_method symbol.

Apache Benckmark "ab" conditionally compiles call to SSLv2_client_method() depending on OPENSSL_NO_SSL2 define that is not present in the openssl port's headers if built with default OPTIONS.

So, there is nasty bug when build uses openssl port's headers with base system's openssl library.
