Undefined function or variable 'LSDDetector_'. #435

Closed Dzhange closed 5 years ago

Dzhange commented 5 years ago

when I successfully built mexopencv on my Mac, I got this error

Undefined` function or variable 'LSDDetector_'.

Error in cv.LSDDetector (line 48)
            this.id = LSDDetector_(0, 'new');

when I run

a = cv.LSDDetector()

I think maybe somehow I failed to biuld mexopencv with opencv_contrib. also, I'm building with opencv3.4.3, which is default on homebrew, does it matter? Is there any solution?

Well, I read the Makefile and found that I have to add "contirb" at the end of the command. I think you should include this in the Readme.

Hi. I believe we do mention the "contrib" target in the README file, it's listed under Linux section though (macOS and Linux instructions are really the same, except for package managers):

To enable support for contributed modules, you must build OpenCV from both opencv and opencv_contrib sources. You can then compile mexopencv as:
$ make all contrib

As to the version, yes I suggest using the supported version (v3.4.1 currently), otherwise you might get compile errors. I'm working on updating to the latest releases.
