------- Additional Comments From julliard@winehq.com 2007-24-05 09:52 ------- If it finds the headers but not the lib at compile time it will fallback to trying to load the plain .so at runtime, because that's more useful than failing. What you could do is add a warning about that case in configure --verbose.
