building linuxcnc-dev on ubuntu 16.04 preempt-rt kernel

cd linux-4.9.47 says no such directory now, and running the following patch update says "I can't seem to find the patch anywhere.

Dpkg says no file or directory, are you aware of what the issue there is?

we need more information about what you did to help you. Make sure you are using correct kernel , installed require packages.

While following this tutorial, I am to the point of running the "./configure --with-realtime=uspace" to configure LCNC. I get the following error:

checking for img::png using /usr/bin/tclsh8.4... no
configure: error: Tk img::png not found!
install with "sudo apt-get install libtk-img"

However, libtk-img is installed. I am using a fresh install of Ubuntu 16.04

Any suggestions as to why I may be getting this error?

Thanks,
Joe

Hi i get the kernel also working with draftsight 64 bit.

In the menuconfig i see this :
kernel hacking menu : IO delay type (no port-IO delay)
I choose no delay, standard is with delay, somebody advise?

I had error to solve :
Error : the frame size of 1056 bytes is larger than 1024 bytes
Solved with : menuconfig => Kernel Hacking Menu => changing frame size from 1024 to 2500

I had error to solve :
Boot directory no space available anymore.
Solved with : deleting old files with command : sudo rm filename

I used the tutorial kernel links :
wget mirrors.edge.kernel.org/pub/linux/kernel.../linux-4.9.47.tar.gz
wget mirrors.edge.kernel.org/pub/linux/kernel...4.9.47-rt37.patch.gz

If i want to install the latest kernel file combination.. Is it better to do this, or leave it like this?

Many thanks for this nice tutorial.



For the one's who are not able to install this 64 bit configuration. Maybe i can sent a pre installed hard disk around the globe.

It might be that you have to force a version. I think you can do this in Synaptic.
