I now have

hamish@hamish-Presario-CQ57-Notebook-PC ~/linuxcnc-dev $ dpkg-checkbuilddeps
dpkg-checkbuilddeps: error: Unmet build dependencies: docbook-xsl yapps2

You'll have to find them in the repos. Look at the first few post and you can find the website/repo to find those.

When installing it will be
sudo apt-get install xxx (yaps2, ect...)

And look for a dependency for docbook-xsl.

Let me know if you can not find them.

I have to really thank you for your patience with me. Programme is now up and running
When I get the welcome screen and select a configuration the programme does not start full screen but only shows on the very bottom title bar, one click brings it full screen. Will look into laptop set up as it may be there.
Does not really mean much to me, but ran a latency test and it is horrendous, suggesting this laptop will be useless for actual control but will allow me to learn.
Thanks again for your help

You're welcome.

A laptop is ok to learn with but not to run a controller. So when you get the process down pat you will be ready for the real install.

A laptop will not work because of the latency induced from power saving features.

Hello, I'm installing this on a Touchsmart 9100 and got thru the kernel build. I installed the .deb's and everything I could. The only files left were txt and .gz. It didn't seem like it updated the boot loader though, it finished pretty quick. I installed grub customizer and moved the 4.9.4 kernel to the top. After I rebooted it came up in failsafe mode. I rebooted again and now it starts loading Mint 18.3 and then starts beeping with a black screen.
Grub only lists my hard drive and no kernels so I'm not sure what to do now.
Any suggestions?
I'm using Post 2 on the first page to install.

I was just able to change to the original kernel after pressing shift.
Any idea what I could have missed it did wrong to have it crash like that?

For first thanks for your work ...

I do not always follow the forum or mailing list so I completely lost my progress on ubuntu / mint 64bit and RTAI. .... The 4.x kernel version that you say about Kuminzky corresponds to the RTAI 5.1 version + adaptations made by kuminzky for LCNC? In any case, despite being a version dev. does he work on a real robot (scara / puma / delta) or is it just sim?

I wrote here because my question on mailing list is missing.

I don't know if he is running a robot or not. Sorry maybe someone else can chime in and tell us.


Did you have any missing dependencies?

Is this the latest master version? Looks like you are running a sim Hal. But you are in realtime so at lest the kernel is good.

Have you tried looking at the last import .hal before the error?

My entering of the long code at post 4 rendered being unable to locate Tcl18.6-dev, tk8.6-dev. First line of the Kernel install wget resulted in unable to resolve host address. Didn't try the patch following given that not working. Couldn't continue from there, assuming it all stacked on itself. Any ideas?
