Hello,

I am trying to build the project of ORB_SLAM2 from this repository.

I have installed all the required dependencies that are mentioned in that repository. However, when I run

./build.sh

I get this error:

/<path_to_folder>/ORB_SLAM2/include/ORBextractor.h:26:23: fatal error: opencv/cv.h: No such file or directory

I have installed opencv4.2.0 from source in a docker image and I want to build the mentioned project in a docker container. I have been looking around how I could get the cv.h file, but I didn't find anything and that's why I am making this post.

This is the Dockerfile I used to create the docker image with opencv4.2 and cuda 10.2

Thank you very much,

Jordi

opencv 4 does no more install the deprecated (1.0) c-api headers.

you can either patch the ORBExtractor.h and use

#include <opencv2/opencv.hpp>

(luckily it's only one case, all others were changed already)

if you can't, you'll have to use opencv3 instead.

Okay! I will install the latest version of OpenCv3. (3.4.9?)

Thank you!

why not fork the ORBSLAM repo, fix it, and use that instead ?

(editing the file from a webbrowser will do that for you !)
