    Default Patient expert needed for newb RTAPI error

    I'm a complete newb trying to install EMC2 into Ubuntu 8.04 Hardy Heron to control a homebuilt gantry router.

    Ubuntu runs well, and installed easily on a separate hard drive on a 2.0 Ghz Sempron 3400+ Emachines desktop with 3Gb of RAM.

    I tried first to install EMC2 separately, then also with the EMC2-Ubuntu Live CD ISO image burned onto a CD.

    Same error both times: it seem I get a RTAPI error / segmentation error which I have no idea how to solve.

    All input welcome - Thanks

    error text follows:

    Default Update

    I tried the run from CD option, with the same results.

    Then I tried it on a Dell Vostro 400 and it worked just fine. EMC2 seems to do exactly what I need.

    So I know the Disk ISO burned well.

    Still no clue about the RTAPI error on the other machine. Maybe it has something to do with the nVidia card? Both have a full complement of RAM and are running XP Home.

    Thanks again to those that have looked at this thread.

    While I don't know what gives you the error there is some good info on this page

    Thanks John.

    I've tried to fight through that page, but am still swimming in too deep water understanding what it all means.

    In a bid to work around this problem I've been looking at the Linux powered Everex gPC2 TC2512 Desktop at Walmart.

    According to the reviews, many people seem to have easily installed Ubuntu on it.

    Has anyone used it or see any reason why it would be unsuitable for a EMC2 machine? For $200 it seems quite a deal.

    Kind Regards

    David

    One problem with that WalMart machine will be the integrated graphics. Can a graphics card be added? From the spec sheet it looks like the answer is no, but I may be reading incorrectly.

    "real time system failed to load.". Not sure what would cause this. I've also had hard luck with an emc install. On that particular machine no amount of messing in the bios solved the problem. However in that case the problem was seemingly random latency errors.

    Maybe a good wiki contribution would be a build sheet. Something like;
    "Go to NewEgg and buy exactly these components, use exactly these bios settings, and exceptional realtime performance is guaranteed."

    Random thought: Linuxcnc.org could sell computers ready to roll. This has probably been considered and rejected for good reason.

    Just another thought, I had one computer with windows and the live CD would not work (I forget the exact reason) I took out the hard drive with windoz and put an blank hard drive in and danged if it didn't work and is running my plasma cutter to this day...

    At this point I'm positive that I don't know about all the things I don't know anything about when it comes to Linux...

    As a Linux newb who likes to start using, then learn alongside the user experience, a list of tested hardware and setups would make life so much easier. Hence the search for a reasonably priced off the shelf box - but WHICH one?

    I believe you are right about the video: This link shows no video slots.

    I have an optimistic (probably unfounded) hope that as it is sold as a Linux machine and people have run Ubuntu on it that the manufacturer at least knew that linux compatible video would be a factor.

    Is it at all safe to assume that if Ubuntu works well, then EMC2 would too?

    Maybe I can try it and then return it if the live EMC2/Ubuntu CD doesn't function well...

    Though John's reply seems to indicate that all is not always logical when Linux and compatibility is concerned.

    And it could have been the Windoz causing the problems... So take your live CD down to WallyWorld and boot up the computer you want and check the latency... What can they say...

    Hey oakes3

    I think your problem is that you do not have Ubuntu booting from the real time kernel. What you need to do is install grub editor and edit your grub so that the real time kernel loads by default. I have installed EMC2 on Ubuntu Ultimate 1.8 and had the same issue when I updated and updates installed a newer kernel. I had to edit the grub and revert back to the real time kernel. Good luck.

    The problem with some onboard video controllers is that they have too much latency to work well with the real time needs of EMC2, not that they don't work well with linux.

    Is it at all safe to assume that if Ubuntu works well, then EMC2 would too?
    NO. It must work well with both Ubuntu and the real time kernel.

    Maybe I can try it and then return it if the live EMC2/Ubuntu CD doesn't function well...

    Though John's reply seems to indicate that all is not always logical when Linux and compatibility is concerned.
    I don't know the answer to this question, but I would suggest asking the seller that question. There has been discussion of certain motherboards that have on board video controllers that do work well with EMC2. I have this one bookmarked. I don't own one so I can't personally vouch for it.

    Yes, sorry for not stating that more clearly. If the onboard video turns out to be a problem, what? No AGP or PCIE slot. Would a regular pci graphics card work? I'm not a hardware guru by any stretch.

    Maybe the UniChrome onboard would work. Depends on the motherboard probably?
    http://wiki.linuxcnc.org/cgi-bin/emc...l?Latency-Test

    I'd just hate to see you buy a unit specifically for emc2 and be disappointed

    I'm still curious why the realtime modules fail to load. According to the first line of the kernel messages you are running the realtime kernel. Or at least that's how I read it. Will check my dmesg later to compare if no one responds earlier.

    Here's the output on my 8.0.4 booting a realtime kernel.

    [ 0.000000] Linux version 2.6.24-16-rtai (root@dana-laptop) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 Sun Apr 13 17:50:16 EEST 2008 (Ubuntu 2.6.24-12.22-generic)

    "uname -r" reports this
    2.6.24-16-rtai

    However this machine is setup for simulation only and normally boots 2.6.24-19-generic.

    Did you try the emc2-install.sh script? The result would be the same as using the emc distributed cd afaik, which apparently fails in the same way. Weird. Something about your install feels wrong. Can't be more specific for now.
