Don't worry about re-creating anything, I think I understand what was happening now. > I'm using amd64 as well, but am currently with the stock Debian > 3.2.0-rt kernel.

Michael's original patches only provided a parallel port raw I/O driver (which he said worked for his tests but was not ideal), so if you want something besides that (or the odd thing the bitmuster folk have), you'll have to do some coding. >> I'd be happy to supply you with what I have so far.

It includes all the changes I described, and you may find some surprises in there, too. It applies against commit 0cb04933ab03e7ebef96f78f180685702953f142, as the filename indicates. http://www.zultron.com/static/2012/04/linuxcnc-0cb04933ab03e7ebef96f78f180685702953f142-linux-rt-plus-2012-04-24.patch The list of fedora packages I had to add to compile it: BuildRequires: gtk2-devel libgnomeprintui22-devel BuildRequires: mesa-libGL-devel mesa-libGLU-devel BuildRequires: tcl-devel tk-devel bwidget libXaw-devel python-mtTkinter BuildRequires: lyx pth-devel dblatex libmodbus kernel-devel blt-devel BuildRequires: asciidoc >= 8.5 Compile script: ./autogen.sh ./configure --with-realtime=linux \ --with-tkConfig=%{libdir}/tkConfig.sh \ --with-tclConfig=%{libdir}/tclConfig.sh \ --enable-build-documentation make > So far, I don't have much but some cryptic notes to myself I'm keeping > on a wiki page at the LinuxCNC site: >> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Wheezy_Linux-Rt_Compile_LinuxCNC Thanks!
