OpenCV:Ubuntu:NetBeans:cvSubdiv2DEdgeOrg “undeclared”

Question

I am using OpenCV 2.4 with NetBeans 7.0.1 on Ubuntu 11.10.

When I try to compile code that contains the following

CvSubdiv2DPoint* pt = cvSubdiv2DEdgeOrg( t );

I get the following compilation error

error: there are no arguments to ‘cvSubdiv2DEdgeOrg’ that depend on a template parameter, so a declaration of ‘cvSubdiv2DEdgeOrg’ must be available [-fpermissive]
note: (if you use ‘-fpermissive’, G++ will accept your code, but allowing the use of an undeclared name is deprecated)

When I right click on CvSubdiv2DPoint and choose Navigate:Got to Declaration/Definition, it is defined in types_c.h. I do not understand how I get get to the definition if it is allegedly "undeclared". Also, if I include

#include "types_c.h"

and make sure that types_c.h is in the include path, I still get the error message above.

Any assistance in resolving this problem would be greatly appreciated,
Peter.

It was moved to legacy. You need to include its header:

#include "opencv2/legacy/legacy.hpp"
