count objects & polygons opencv.js Hi, I'm working with the watershed algorithm example, here https://docs.opencv.

Hi there,

I set environment variables JAVA_HOME and ANT_HOME. But when I do cmake -DBUILD_SHARED_LIBS=OFF .. it doesn't say "java" in the "to be built", and further down where it says "Java", it says ant: NO.

Why is it saying "no" for ant, and why is it not picking up java? What does it want??

Thanks!
