I think that info is kept in /etc/rc.d/PUPSTATE

Already solved, but thanks!

Right now working on getting the LinuxCNC program itself, since Puppy doesn't use apt get,

I was able to download a CNCLinux 2.54 .deb, and try it out, but I'm afraid things are not going to work this way.. The binaries require a specific kernel -- they abort with a message after testing the kernel. The 2.5.4 linuxcnc version wants kernel 2.6.32 - 122-rtai to run.

This Lupu 528 has 2.6.33.5-rt25.

And I also don't know the difference between rt and rtai as mentioned by Revolverve earlier -- sorry I missed that post Revolverve -- i must have been typing at the same time.

Compiling the program is probably the only way unfortunately, I really doubt any of the binaries exactly match the particular kernel I have in the modified Lupu 528,

Do I recall reading somewhere here about someone changing the name of a kernel?

I dunno maybe that's getting too kludgy. I would like to find that reference,though.

This is about as far as I'm going to get at this point. I'm pretty sure there are solutions, but I'm not knowledgeable enough to get there from here.

Maybe someone else can take it further.

kernel source 2.6.32-122-rtai
Located at
http://linuxcnc.org/dists/lucid/base/source/

Found that info at
http://sourceforge.net/p/emc/mailman/message/31174742/


edit: Seems all kernel sources here
http://linuxcnc.org/dists/

Okay perdido, thanks. Well guess I'll try to compile my first kernel then and see what happens.

Suggestion; Try using DebianDog as it`s truly pure Debian and the .deb will work.
Saintless and Fredx have done an excellent job making it very Puppy like.
And it overcomes many of Puppys problems and will use Precise SFS files.

How about a link from where DebianDog can be downloaded?

Hi sunburnt -- would debian dog run well on an older computer with limited RAM resources and a P3 processor like the Thinkpad 600E?

And second would it run on that same computer with a version of LinuxCNC?

Remember, the reason for picking a puppy Lucid and not Precise is because no Linuxcnc binary was created for Precise, while it was for Lucid.

There is in existence a Debian LiveCD for LinuxCNC. But the Debian (latest) LiveCD ISO of LinuxCNC is 1.1 Gig.in size Shocked

Since it can't be installed via LiveCD (needs DVD) and many older bios's can't boot through USB, it is difficult to go the LiveCD method to test it out on an older machine, or install it. LinucCNC ISOs have more than doubled in size recntly since going to ver. 2.6 from ver 2.5 and changing from Ubuntu to Debian.

I was hoping we could go in the opposite direction and Puppy style, with a very low overhead, fast, small liveCD for a dedicated control machine using older hardware.

vtpup; I understand your desire for a very small distro for older equipment.
I have an old Celeron box, perfect for a CNC controller, won`t do much else.

Here`s the forum thread for DebianDog, it`s the same size as most Puppies.
Talk to Saintless ( Toni ) and see if he has any suggestions.

The Plop bootloader may allow your older machine to boot from a USB stick.

Agreed that using Puppy would be preferable Cool

Sunburnt thanks for the lnk, but it doesn't seem like it's likely built on the right kernel for LinuxCNC, which seems to be very exacting in its requirements. Unless I'm not uunderstanding something (very likely!)

Thanks Les Kerf I'll look into Plop, since thet would be handy to have.

But I don't think I will be using it for the 1.1 gig Debian LinuxCNC distribution, since the TP 600E has 290 megs of available memory at present.

The proper way to do this would be to compile the proper kernel to match the Ubuntu 8.04 or 10.04 LinuxCNC/Ubuntu binaries, and then build a puppy from the appropriate Ubuntu repositories on that kernel using Woof. I'm tempted to try, but I have never done either before, and I bet there are special problems integrating Puppy and LinCNC along the way as well.

I might try, but it would take me awhile to study everything and learn it. Not somethng that's going to appear here quickly, as I had hoped byt combining a RT kernel and Lupu. I hadn't realized how specific the kernel requirement had to be.
