Hi,
I want to interface OpenCV from julia. For that I was directed to install Cxx,jl. I Followed the instruction given in the website https://github.com/Keno/Cxx.jl. 1.Successfully build Julia. 2.Downloaded and build Cxx.jl. Examples given in the website are executed sucessfully. But build error occurs while trying to install OpenCV.jl julia> Pkg.clone("https://github.com/r9y9/OpenCV.jl.git";) INFO: Cloning OpenCV from https://github.com/r9y9/OpenCV.jl.git INFO: Computing changes...
