Opencv installed but not working in c++

what does it do, exactly ?
if it installs prebuilt opencv libs, problem might be, that they were built against a different version of vtk, than you have locally

That is not the problem because arch builds them on the fly for you. Is there a way to install opencv viz module correcty. I am not sure if i am using them but the error still persists.

@berak

maybe, ditching the pkg-config approach in favour of an explicit g++ cmdline can give you more finedgrained control on what you’re actually linking

I tried using Cmake but the same error came.
