I have tried for a number of days to build Kicad from source under WIndows 10.
I have followed the instructions exactly at http://docs.kicad-pcb.org/doxygen/md_Documentation_development_compiling.html#build_windows (both the easy way and hard way). These crap out with errors related to making a component. I filed a bug report (https://bugs.launchpad.net/kicad/+bug/1752150) but there has been no action/reply.
I also tried using kicad-winbuilder. It also craps out (not surprising given both are based on msys2. I also filed a bug report on that https://github.com/KiCad/kicad-winbuilder/issues/58. There was a bit of back and forth discussion but nothing remotely useful. Kicad-winbuilder is a bit of a problem because it wants to install Msys2 every time you run it. Kicad-winbuilder also has obsolete instructions for updating though, as I note in my bug report, even the updated one (pacman -Syuu) doesn’t work the way it is supposed to. (It works fine in my other instance of msys2.
Obviously, the issue could be with my set up although I use msys2 regularly for development. Nonetheless, both make instructions work with msys2 and they could be out of sync with updates to msys2.
Any help/guidance would be appreciated.
