Hi, Sorry for reopening an old thread (May 2011), but I just want to report that I'm using HOpenCV and cv-combinators under windows and I just wanted to tell you that it works just fine. I downloaded the opencv2 libraries as stated on this thread, and I'm successfully building software that works both on Windows (XP and 7, both x86) and Linux (x86 & amd64). The software will be released in a few days, if everything goes well. You'll be able to find it at keera.es, but I'll let you know when I release it anyway. Cheers, Ivan Perez. PS. I just re-subscribed to this mailing list. I can't reply to the old messages (don't have them), and I can't set the old Message-ID with gmail, so I'm providing a link to the original message.
