MySQL 5.6 fails to build with libwrap support enabled.

sql/mysqld.cc: In function 'void handle_connections_sockets()':
sql/mysqld.cc:6202: error: 'connection_tcpwrap_errors' was not declared in this scope

which on line 6202 is..

          statistic_increment(connection_tcpwrap_errors, &LOCK_status);

but there is no variable connection_tcpwrap_errors and the other associated code with keeping track of the number of connection errors there are from libwrap.

How to repeat:
Build MySQL with libwrap support.

Suggested fix:
Add the missing code after the statistic counters were added.

I can't repeat on Centos 6.3 64-bits compiling 5.6.7 source package.

The screenshot and info you posted doesn't prove it is even enabled during the build. You're doing something wrong.

Wow. Incompetence at Oracle.

I can repeat on Ubuntu 12.04 64bit with MySQL 5.6.9. The variables were renamed a  while back but that line was missed. It should be connection_errors_tcpwrap, and not connection_tcpwrap_errors.

Nathan, thanks for pointing that out. You are correct.

Noted in 5.6.11, 5.7.1 changelogs.

MySQL failed to build if configured with WITH_LIBWRAP enabled.
