I tried to build kicad from source but ran into a problem. I built wxWidgets statically and kicad build failed when it couldn't find wxwidgets3/lib/libwx_gtk2u_aui-3.0.a (maybe not exact but close enough) while trying to build cvpcb.
I'm thinking that wx3 is too new, I may retry with wx28. I rebuilt wx3 many times trying to coerce it into making that missing library but had no success. The other .a libs are there.
I'm not in a bind or anything, I just want to look at one of these pcb programs.
