intalling Linuxcnc from source

Hello,

Iam trying to download LCNC from source, on Ubuntu. Iam following this steps: www.myheap.com/cnc-stuff/linuxcnc-emc2.html .

I have finished the compilation of real time kernel (tutorial 2) I had to make some modifications, because I had some errors, but these I was able to solve with google. (I AM ABSOLUTELY BEGINNER with linux - I have a machine on linuxcnc but now I want to do even some serious tasks, with lcnc and dive into a little bit more).

Now Iam doing part 3. installing LCNC from source and I got stuck here :
 

Basically I have to download required dependencies, which are required when I type:
The author has different (older version) requirements to I basically copied all necessary and tried to download them with:
But it gives those unable to locate errors...

I tried to solve this with:
but no success...

any ideas? I continue in searching for solution but maybe Iam doing something absolutely wrong

What version of Ubuntu?
Latest versions can have LinuxCNC installed with a single line:
sudo apt install linuxcnc-uspace
But Ubuntu will not install the RT kernel, so you can not control machines with it.
Ubuntu requires paid version for access to RT kernel.
You can use Linux Mint Debian Edition 6, it does install everything with that same line, and can control machines.

I think there is some of the newer ubuntu version. Thats strange because I was somehow able to compile PREEMPT-RT, as you can see in the screenshot, I used the command uname -a,and you can see whats there. 

With sudo apt install linuxcnc-uspace I will get only latest version? What if I want also another versions? I assume this will also somehow need git.
But as I said Iam not experienced. So perhaps make new installation with Linux Mint and try again to download PREEMPT-RT and then linux? 
Also I think I had some problems with preempt-rt compilation, maybe I can somehow check if its even working?? 

So now I will probably try this  gnipsel.com/linuxcnc-old/uspace/linuxmint18-rt.html .
I read somewhere that uspace is required if I want to use mesa card, which I want to use via ethernet connection 7i96s or 7i92.



thank you

 

Why do you want to use Ubuntu instead of Debian? You would have less of a problem with Debian.

Ubuntu Pro is free for personal use and this gives access to the RT kernel.

Is there a guide on installing LinuxCNC on ubunto pro? How do you install the realtime kernel? Which packages must be used for the installation?
