I am using OpenCV 2.3.1 to develop Delaunay triangulation code on NetBeans 6.9 on Ubuntu 11.04. I have included all of the libraries that I could find in the link list but get the following error messages when I try to link.

build/Debug/GNU-Linux-x86/_ext/1942517469/TwoDTriangulation.o: In function `cvCreateSubdivDelaunay2D': 
/usr/local/include/opencv2/imgproc/imgproc_c.h:376: undefined reference to `cvCreateSubdiv2D' 
/usr/local/include/opencv2/imgproc/imgproc_c.h:378: undefined reference to `cvInitSubdivDelaunay2D'
