Had a look at the forum thread in linuxcnc, sounds interesting.

There is obviously a github repo somewhere you have shared with Michel Wijnja

If you would like to do the same, I will be happy to test build.

HI Travis,

I will be interested to have a look at this later.

The includes you want should be in the flavor package

https://github.com/machinekit/machinekit/blob/master/debian/machinekit-rt-preempt.install.in#L4

We don't have a -dev package and each kernel has a specific sub package which also contains the includes etc.

I suspect you may have just installed machinekit, whereas you need 'apt install machinekit machinekit rt-preempt' for instance.

I will check the package contents later, but see no reason why those would be missing.

regards

I'm working on a GUI that's meant for embedded applications with fairly low resources. It's C and C++ based and runs entirely without X, deals directly with the framebuffer and evdev for mouse & keyboard. (Touchscreen also supported)

I have a post here about it https://forum.linuxcnc.org/41-guis/35225-new-gui-for-embedded-systems. I posted here to figure out how to talk to LinuxCNC via C (libNML) and this has all been figured out most part. My trouble now is when I try to build against machinekit, there is no /usr/include/linuxcnc. (or /usr/include/machinekit either) Specifically I need "<linuxcnc/emc.hh>" & "<linuxcnc/emc_nml.hh>" equivalents for MachineKit. I know this project was forked a while ago but I believe the NML interface is the same.  Could someone here point me in the right direction?

Right now the GUI runs on LinuxCNC on a regular Intel-based PC just fine and the only hang-up in migrating to our ARM platform is this little difference between LinuxCNC and Machinekit.

I think this GUI will be a great addition to this project because it will allow people to use HDMI or virtually any type of display from Beagle Bone, Rasp Pi, or other embedded devices that Machinekit has been ported too and not have the "click and wait" lag.

Thanks,
Travis
