Getting the Latest OpenCV via CVS
OpenCV is under active development, and bugs are often fixed rapidly when bug reports contain accurate descriptions and code that demonstrates the bug. However, official OpenCV releases occur only once or twice a year. If you are seriously developing a project or product, you will probably want code fixes and updates as soon as they become available. To do this, you will need to access OpenCV's Concurrent Versions System (CVS) on SourceForge.
This isn't the place for a tutorial in CVS usage. If you've worked with other open source projects then you're probably familiar with it already. If you haven't, check out Essential CVS by Jennifer Vesperman (O'Reilly). A command-line CVS client ships with Linux, OS X, and most UNIX-like systems. For Windows users, we recommend TortoiseCVS (http://www.tortoisecvs.org/), which integrates nicely with Windows Explorer.
On Windows, if you want the latest OpenCV from the CVS repository then you'll need to access the CVSROOT directory:
:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:2401/cvsroot/opencvlibraryOn Linux, you can just use the following two commands:
cvs -d:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:/cvsroot/opencvlibrarylogin
When asked for password, hit return. Then use:
cvs -z3 -d:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:/cvsroot/opencvlibraryco -P opencv
