Here's a link to the latest patches:
http://www.zultron.com/static/2012/04/linuxcnc-buesch-rt-patches-forward-port-2012-04-25.tgz
The README explains how to compile them on FC16.
A few changes from the last version:
- Now three patches 001-003 that parallel Michael's original patches. I
thought that may be useful at some point.
- I missed a line in the last version's Makefile which caused the
drivers not to be built. It is present in these patches.
- Patch 100 are simple changes that help a few drivers to compile, and
disable a few drivers that won't compile (probably easy fixes).
- Sebastian Kuzminsky helped put a couple of little fixes into the
master branch today (thank you!!!), so the whole set feels pretty clean.
I still haven't even gotten a chance to run these yet! Tomorrow. Must
sleep.
