Meh

I did this if this is what you mean

what kernel are you running ?

uname -a

Thanks for the instructions - I have followed carefully -but when i get to "dpkg-checkbuilddeps"
I get error message "dpkg-checkbuilddeps: error: Unmet build dependencies: rtai-modules-3.4-9-rtai-686-pae intltool" How do I add this dependency? I thought it was already there?

Any help appreciated ...

Many thanks,

Did you do step 1 first? gnipsel.com/linuxcnc/uspace/linuxmint19-rt.html

I can confirm that as of today, 25-Apr-2019, the instructions provided by BigJohnT worked perfectly. The only change I made was to run 'make -j4' instead of just 'make'. Speeds up the kernel build considerably.

Great Job BigJohnT!

I can also confirm that attempting to do the same instructions using just Ubuntu 18.04 LTS fails, so Mint is adding some other packages that are needed by LinuxCNC.

One quick question though: Is there any advantage to building the latest Preempt_RT kernel instead of the .1 version? I think the latest build with _RT is .31.

I assume as they fix things it's better to use the latest version but you know what assume means lol.

Assumption = the mother of all f###ups !
Very true.

Thank you for the instructions.

I currently have Linux Mint 19.1 installed – and want to install linuxcnc.

I followed carefully but my computer fails to restart after finishing step 1. gnipsel.com/linuxcnc/uspace/linuxmint19-rt.html

Any help is appreciated

You will have to explain what actually happens, "fails to restart" is pretty vague.

Can you still boot using the old kernel....it may be under the Advanced options menu item.
