    You probably have code written for an older library. Have a look at the header file, I guess the constructor has only 3 arguments. Remove true, then it should work.

    This discussion might point out the problem with more details: http://tech.groups.yahoo.com/group/OpenCV/message/61534 to help you finding a maybe more suitable solution if simply removing the flag does have some undesirable side effects.
