Hi Nick.
I copied your code (removing the * delimiters, which I guess you use just to emphasize the important parts), but couldn't get either to compile. The code I used is attached. Use the #define USE_LAM_PRO to select which version to compile.
Could you modify the attached so that it does compile? I'm using gcc-4.7.
Hi Larry, Sorry about the extra formatting - in Gmail that's bolded, but I guess I should stick to plain text... I modified the code on ideone <https://ideone.com/MVYDj> and it compiles fine (gcc 4.3.4) - my guess is it won't give you any trouble. The main thing I changed was moving the ::type access from outside protect to inside (it should refer to the inner lambda), although I also added a couple includes for form and a main function so it would work online. -Nick Kitten Software Engineer Center for Video Understanding Excellence ObjectVideo, Inc. http://www.objectvideo.com
