Hello,
for many hardware project in tinkerforge, when we open the schematics inside kicad we get a message saying that the library "special" is missing.
Actually, there was a problem in kicad solved on may 22nd regarding this library problem. See https://forum.kicad.info/t/the-following-libraries-were-not-found-special-solved/870/2 and http://bazaar.launchpad.net/~kicad-product-committers/kicad/product/revision/5678 (the file template/kicad.pro).
At least industrial-dual-0-20ma-bricklet and ac-current-bricklet project have this problem.
I attach a patch fixing the problem for ac-current-bricklet.
Regards.
Thomas. patch_lib_special.diff
