[OS X] xphoto issue

[ghost]

Hi guys. I'm using OS X Sierra 10.12.1. I have install OpenCV with brew by the following command:

brew install opencv3 --with-contrib --with-ffmpeg --without-numpy --HEAD

When installing torch-opencv with the command:

OpenCV_DIR=/usr/local/Cellar/opencv3/HEAD-ecb8fb9_4/share/OpenCV luarocks install cv

I encountered the following error:

Please help.

Hi!

The bindings are targeted at OpenCV 3.1.0. autowbGrayworld is absent in trunk but present in 3.1.0. So, there are 2 solutions:

• use OpenCV 3.1.0 stable: invoke brew without --HEAD
• don't generate xphoto bindings: do OpenCV_DIR="...your opencv dir" DONT_WRAP=xphoto luarocks install cv

Thanks shrubb!

1. I cant reinstall it with the following command:

brew install opencv3 --with-contrib --with-ffmpeg --with-python3 --without-numpy

That yield some errors.

2. The second solution worked like a charm.

Glad it helped!
