EMC2/LinuxCNC Port Or Package

F

FreeBSD'ers,

How far has anybody gotten with porting LinuxCNC (used to be EMC2) to FreeBSD? Currently it's 'pre-packaged' with Ubuntu. I like PC-BSD/FreeBSD better! :)

Have A Nice Day!
 
I'm working on it. It's running fine, although in simulation-only mode for now. I'm slowly pushing my changes to the upstream, and will follow up with a proper port soon.

Had a chance to test the cad/linuxcnc-devel port tonight and it loaded to the configuration selector. Looks Good. Build took quite a while.
You know the next question. When do we get more than simulaton..
Actually porting over the realtime stuff must have been fun.

Great Job. When I get a chance I want to test this on ARM. Will it build??

I see on LinuxCNC forums where people are overclocking their Raspberry Pi to get it to perform better. So it is scraping on the low end of hardware requirements. I will stick with x86.

Would be nice to get this working with FreeBSD GPIO's.
 
Well I fired off a make install clean tonight on a RaspberryPi2. It took over 1 hour on a Ivy Bridge quad. So I am guessing 20-30 hours on Arm.

I am just discovering SSH's flexibility and it is great.
 
Well it failed after 8 hours compiling on RPi2. Was worth a try.

I give up on building this on Arm. Was worth a shot.

How does this look?
