linuxcnc on 64bit OS

BTW i did not try the debian kernel, but i have been sucessfull with the kernel provided here

bitbucket.org/thismaechler/ubuntustudio-14.04-realtimeaudio/

3.18.7-rt1

Good.

rt1 is very early, PCWs scripts pull rt7 I think and I have built rt10 recently

You may find a later rt version more stable and lower latency still, a lot depends upon the computer really, as to how well rt-preempt runs on it, but yours seems OK.

see how you get on

regards

Here's a script for building 3.18.13-rt10

cd ~
mkdir rtlinux
cd rtlinux
wget ftp://ftp.kernel.org/pub/linux/kernel/v3.x/linux-3.18.13.tar.xz
wget www.kernel.org/pub/linux/kernel/projects....18.13-rt10.patch.gz
tar -xpf linux-3.18.13.tar.xz
gunzip patch-3.18.13-rt10.patch.gz
cp patch-3.18.13-rt10.patch linux-3.18.13
cd linux-3.18.13
cat patch-3.18.13-rt10.patch | patch -p1
sudo apt-get install libqt4-dev
make xconfig
make -j2
sudo make modules_install
sudo make install

Note that you may want to trim a lot of uneeded drivers
perhaps by running "make localmodconfig" before make xconfig
if you expect the kernel/drivers to only run on the compile system

Thank you so much.

I have been able to build the kernel and install it, and build Linuxcnc on it

Thank you for all your help
