OpenCV issue - git

[philosopher]

I think nearly all of my OpenCV skill problems center around trying to update the git submodule, specifically the command is:

git submodule update --init --recursive

When typing sudo make in the OpenCVSkill folder, it will build for OpenCV and install the binaries, but when it goes to the skill folder:

make[1]: Leaving directory `/go/src/skill/opencv-2.4.13.2/platforms/linux/build_hardfp'
cp -R ../opencv/artifacts/include ../opencv/artifacts/lib robot/deps
git submodule update --init --recursive
Submodule 'examples/OpenCVSkill/skill/robot/src/vendor/github.com/lazywei/go-opencv' (git@github.com:lazywei/go-
opencv.git) registered for path 'robot/src/vendor/github.com/lazywei/go-opencv'

and the repository exists.

make[1]: Leaving directory '/home/philosopher/Programs/mind-sdk/examples/OpenCVSkill/skill'
Makefile:4: recipe for target 'build' failed
make: *** [build] Error 2

If I try to run sudo mind build in the skill folder, it gives:

robot/src/skill.go:14:2: cannot find package “github.com/lazywei/go-opencv/opencv” in any of:
/go/src/skill/robot/src/vendor/github.com/lazywei/go-opencv/opencv (vendor tree)
/usr/local/go/src/github.com/lazywei/go-opencv/opencv (from $GOROOT)
/.go/src/github.com/lazywei/go-opencv/opencv (from $GOPATH)
/go/src/github.com/lazywei/go-opencv/opencv
exit status 1

Any help would be appreciated.

This is on Ubuntu 16.04 of course. I cloned the entire mind-sdk and am working inside of the examples folder. It could also be the $GOPATH, but I’m not sure.

Thank you.

Please make sure you have the correct access rights and the repository exists.

From your log, I think the problem is your computer’s ssh key ~/.ssh/id_rsa.pub is not connected to a GitHub account, so it can not clone from git@github.com:lazywei/go-opencv.git via ssh.

However, we should consider this situation, the URL of submodule should be https but not ssh, we already make an update to fix this.

By run following commands it should work now,

$ cd mind-sdk
$ git pull
$ git submodule deinit .
$ git submodule update --init --recursive

If they still any problem please just let us know, and great thanks for your feedback!

Hello! Want to join this discussion. I have one blog with different posts about OpenCV so it’s gonna to be useful for all Vincross forum members. For example you can start from here. It’s about demand and supply of OpenCV developers.
