sys/types.h should be in the build essential package. Did you install that package ?

Running a sudo apt-get upgrade in hopes of that fixing the problem. It's been doing a lot of stuff.

I followed all of the steps in order, is there something I missed?

installed qt 4.8 as it said it needed it. running make -j8 came back saying recipe for target scripts failed. How awful is my luck here.

found a solution for me: $ sudo apt-get install python-pip python-dev libffi-dev libssl-dev libxml2-dev libxslt1-dev libjpeg8-dev zlib1g-dev

So it's finished its compiling and installing at the install without deb step. Since i have the preempt kernel, i skip the install with deb and rtai steps and move on to the reboot right?

I've never installed the debs, just run in place from the command prompt by typing linuxcnc. You always have to run the . ./scripts/rip-environment script to set up all of the environment variables. Check the docs for syntax as the initial '.' is important.

You don't need the debs.
In fact if you are running with the preempt-rt kernel (you can test this with ename -a ) then you probably didn't need to compile LinuxCNC either.

(Though I don't see a Xenial version, so perhaps you did)

When selecting the kernel, I get a VFS Unable to mount root fs error now.
