Can anybody generate opencv.js?

I'm still not able to build it from source.

But this version of opencv.js worked for me on MacOS https://docs.opencv.org/3.4/opencv.js

You can find a nightly build at https://docs.opencv.org/master/opencv.js and some useful stuff at https://docs.opencv.org/master/utils.js .
