Upgrade time, What do I need to know first?

I am getting this error from the new computer. I manually copied cincikins.c and cincikins.o to the /usr/realtime-2.6.32-122-rtai/modules/linuxcnc directory

Hi

For the info of others reading, I have answered what forms post 49288 and a subsequent enquiry re another missing custom component off forum.

You are going to have to zip your config folder in its entirety and attach, ensuring it contains the code to any components.

It is impossible to guess the source of errors within a custom install, with no idea what the files contain

regards

ArcEye,

Thank you for the help. I should have been more clear and included the config folder as soon as I had issues.

Hi

The config is very involved, I presume you have lost the person who originally set it up?

The contents of the zip are puzzling me.

Why is rtapi.ko there? That is the file the error message says it cannot find and it should be in /usr/realtime-2.6.32-122-rtai/modules/linuxcnc/
(Also the version that is in there must be the version from the install, not the old one.)

Also there is no source for spdrerror and the kernel module is there. Is that the one compiled under 10.04 and was it installed?

Your previous error message was from reading the hal file, it had already found and loaded the realtime modules, so something has changed since then and the error is now right at the beginning.

The error at the moment is very basic. It is saying it could not load rtapi.ko
Sometimes things can get screwed up after one failure and the next load fails because modules were never unloaded properly, so try to reboot after a failure if possible

To recap:

You need cincikins.ko and spdrerror.ko built as discussed previously and installed in /usr/realtime-2.6.32-122-rtai/modules/linuxcnc/

rtapi.ko must also be in /usr/realtime-2.6.32-122-rtai/modules/linuxcnc/ - it should never have been anywhere else

After you have ensured that they are there, try booting again

If you get a failure, please post the full details plus a copy of dmesg (do dmesg > dmesg.txt in a terminal and attach the resultant dmesg.txt file)
Please also do ls -l /usr/realtime-2.6.32-122-rtai/modules/linuxcnc/ and post the output so we can see what is in there

Hopefully you have kept your old computer running so are not losing any workshop hours

regards

I am trying to learn this and the person who did the original config doesn't know because someone else has updated the system. That person I do not know.

Cincikins and spderror were built as described.

Something very basic is wrong, why don't you have this directory?

Where are all the files in it plus the ones you compiled?

Are you running a RIP but haven't set the environment variables ( or mentioned it )?

Hi,

Quite honestly I am mystified as to how things can be in such a mess on a recently installed system.

The cincikins module did not build properly, it was unable to link against the rtai libs and it was not installed.

The spderror.mod.c is not the source for spderror and its presence makes me suspect it had previously been built within the source tree in your RIP.
You need to find spderror.c

The module_loader and ls are telling you that the directory that should hold all the modules, does not exist.

I think you need to do a fresh install. This time use the Wheezy DVD iso pointed to on the post at the top of the forum by JT, entitled 'Released 2.6'

It will future proof you for a few years, Ubuntu 10.04 is dead in the water.

Then when installed, start lcnc from the menu and run one of the sims from the sample configs.
That at least will show it is working.

Then build and install cincikins.c from the config dir as before.
comp is probably now called halcompile, but rest is same
Looking for cincikins.ko installed in /usr/realtime-3.4.9-xxxxx/modules/linuxcnc/ and no warning about undefined functions or errors that it could not be copied.

If you can't find spderror.c, you may need to zip your entire RIP from your old machine and host it somewhere on your site so it can be downloaded and examined.

Is this where you found cincikins.c?

regards
