Problems with linux 2.2.10 + beta5 + emc-14-Jun-1999 - anyone ?

Max Heise <[email protected]
Hi, I'm new to the list. Let me first introduce myself.
I'm student at the department of mechatronics/automation at the university of applied sciences in Esslingen/Germany. This is probably kind of offtopic, but is anyone using emc with linux-2.2.x and the rtlinux patches for new kernels from ftp.rtlinux.org ? The kernel and the rtl examples are running fine, but I get lots of errors when building the emc-14-Jun-1999 package - as anyone tried this this yet with success? An other thing for the FAQ: A month ago, i've spend two nights to figure out that emc and the shared memory is quite sensitive to ipfilters like ipchains and ipfwadm. If you get problems with these, flush input/output/firewall rules. If anyone needs the exact error message, send me an email.

It is my understanding that EMC is currently set up for the 2.0.36 kernel

and not yet tested or "supported" on 2.2.x. I am running EMC using steppers on RedHat 5.2 with the 2.0.36-7 kernel and it builds without errors and runs fine. Tim [Denver, CO] ----- Original Message -----

Also Be careful with the release of rt-linux you use. I had problems with
Ver1.1 for 2.0.36 kernels and had to drop back to ver 0.9J which works fine dave It is my understanding that EMC is currently set up for the 2.0.36 kernel and not yet tested or "supported" on 2.2.x.

From: Max Heise <mahe@...>I believe the kernel that Fred and everyone else is using is 2.0.36. I'm pretty sure Fred said that he KNEW emc would not work with a 2.2.x kernel, or specifically, Red Hat 6.0. I don't know the reason for this, but it likely has to do with include files or something like that. Jon |

From: Max Heise <mahe@...>Actually, no. As several other folks have said, you'll need to use the 2.2.36 kernel with rtlinux-0.9J. Are you using RedHat 6.0 or perhaps S.U.S.E. ? If Redhat 6.0, I don't know if you will be able to just drop in the 2.0.36 kernel, or whether you need to regress to RedHat 5.2. If S.U.S.E. (or any other distribution other than RedHat) you are truly an EMC pioneer! An other thing for the FAQ:I just got IP Masquerading working on my Linux machine, and this was my first exposure to ipfwadm (Since I'm running RedHat 5.2 I don't think I have ipchains). Although I think that most machine tool controllers will be behind the firewall, rather than being the firewall, it's probably important to chase down this problem in order to at least understand what's going on. Fred Proctor reads this list and he is also the rtlinux/shared memory guru. See: If anyone needs the exact error message, send me an email.Don't go to a lot of trouble, but I'd like to try mixing firewalling and the EMC on my machine, just to see if I can duplicate your problem under RH5.2. If possible, let me know what you did and what happened and I'll try it out here. Thanks, Matt Shaver mshaver@... |
