I am trying to install the unity-lens-shopping app.
I've downloaded unity-lens-shopping-6.8.0. When I ran ./configure
the first time it complained I did not have the valac compiler. I went to the Ubuntu Software Center and installed it from there. This installed version 0.14.2. Then when I ran ./configure
it said it complained configure: error: Vala 0.16.0 not found.
I went to "https://live.gnome.org/Vala/Release" and downloaded vala-0.18.0. When I run ./configure in there I get "configure: error: flex not found but required". Is there an easier (aka shorter) way to get the lens installed?
