5Axis Kinetic from 2.8 on 2.7x

sudo apt-get install libgl1-mesa-dev

Ok. Maybe it't time to speed things up a bit and try andys advice from earlier.

See how this works for you:

I try to find solutions, but it seems very tedious and difficult to me.

I know this IS the most tedious part of all. That's why pre made install ISOs for USB sticks are made. Unfortunatly, as you have seen, the standard installation of linuxCNC does not cover your specific needs for 5axis machining. So you will have to keep at it.

I found a command which will allow to know all the dependencies of a package to install "apt-rdepends" is this useful for me?

I don't know that command but this exactly what the instructions in my last post were for. dpkg-checkbuilddebs should give you the required dependencies for building LinuxCNC. So type the commands (in red) from those instructions and after the step with "dpkg-checkbuilddebs" you should get a list of all the things that still need to be installed in order to build LinucCNC from source so you can install it as in the instructions.


[edit]
To answer your question as to where I come up with the commands to try:
All I do is google the error you get and try to decide if it might make it go away. I'm no expert but that worked for me when I did it.

Well, you didn't follow the instructions.

in the directory ~/linuxcnc-dev/debian$

you need to run the command: ./configure uspace

after that you run: dpkg-checkbuilddeps

Ok, that complicates things. So lets try if we can get the required key installed.

Import the key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C9F836336AAD909E


try the update again:

sudo apt-get update

If this does not work we'll go back to dealing with the missing dependencies one by one.
