Linuxcnc porting problem

I want to transplant linuxcnc to a real-time operating system like vxworks. Is it difficult? What needs to be done? Can i remove the GUI?

Very interesting question,

Almost impossible to answer.

I depends upon what RTOS you are using and what api it supports, I know nothing about vxworks so doubt I am of any help.

I started working on some stuff that could put some threads on different sections of bcm processors using threadx but gave up very quickly after trying to reverse engineer their boot.bin and having legal problems.

I am sure it can be done but don know if it is economically worthwhile.

Check all the code in github.com/LinuxCNC/linuxcnc/tree/master/src/rtapi and see what needs hooking into the bitop and common code etc...

The base linuxcnc code pprobably could be reasonably easily compiled but the build script often fail due to the huge dependencie burden for the higher level GUI apps etc.

It will take you a fairly long time to get to grips with the code base to workout how to compile just the base level RT code without using a debian system (I would suggest compile it with minimal dependencies on debian then hack apart the makefiles and transfer to your vxworks devel system).

I wish you luck, I assume the more RT kernel support options linuxcnc has the better it could be

As far as i can recall, that RTOS ( there are several RTOS versions ), but Wxworks is based on windows, and that is the main reason i never bothered with it. It was a long time ago, and i never looked back since i bumped into Linuxcnc ( named EMC2 at that time ).
