seamlessClone invoke causes compilation error

edit

please, replace the useless screenshot with a TEXT version of your code / errors, thank you !

and no, this is not a compilation, but a linker error.

What am I missing ?

basic c++ skills, google fu

Ok Ok if you prefer it like that,

Here

//seamlessClone(NULL, NULL, NULL, center, output, NORMAL_CLONE); seamlessClone(img1Warped,img2, mask, center, output, NORMAL_CLONE); imshow("Face_Swapped", output);

For the declarations:

Mat img1Warped, img2,mask,output; Point center;

Sorry if i ask obvious questions but I come from the java world.

Best regards

do you realize, that your question is entirely useless without the image ?
