Questions about the linuxcnc installation procedure under Gentoo

Hello to everyone. I am new at the forum and I am writing a linuxcnc ebuild (package to install from sources) for the Gentoo community. Although I have managed to successfully handle the configuration and compilation procedure in the ebuild, I have trouble to figure out what I am missing on the installation.

The error I get when I try to run linuxcnc as a normal user is this:
LINUXCNC - 2.7.8
pickconfig: cannot find expected start_node </usr/share/doc/linuxcnc/examples/sample-configs/sim/axis/axis.ini>, continuing

Then nothing is shown. Using find, I figured out that I have a /usr/share/doc/linuxcnc/examples/sample-configs/sim/axis/axis.ini.bz2 fil

I made a mistake: Actually a window is loaded, from which I have to choose an example to run. After selecting one, this error comes up:

(gladevcp:6541): libglade-WARNING **: could not find glade file './glade-manual.ui'
**** GLADE VCP ERROR: With xml file: ./glade-manual.ui : could not create GladeXML object
Note: Using POSIX non-realtime


I think I am missing something beyond just a faulty install

Looks like you have a dependency problem or a path issue. Have you looked at the paths from an installed linuxcnc system vs what you are trying to do?

Thank you both for answering.
I think that there is a path-related problem. Should the removal ofis the root of the problem?

Yes, there is an option to use a realtime kernel, but I though that using it as a simulator only doesn't require to use such a kernel. Besides I have to give the users the option to choose not to install such a kernel if that's possible.

Once again thank you very much and please do tell me if you need further information. Have a nice day.

Forgot to mention, no I have not a system with Linuxcnc installed so that I can check the differences.

A good way to check is to simply run the live cd that is available to download. Its a Wheezy distro but you can look at the paths in the system to work backwards.

This could help you figure out what's missing. Or run it in a VM side by side with your ebuild setup. Basically debugging your paths and dependencies. I would think this is the best way.

I'm not sure how linuxcnc dependencies are linked or if ldconfig, is pointing them to their locations or not. It would not hurt to implement it back into your ebuild however. I would assume adding ldconfig could only help unless you have a particular reason to remove it.

EDIT: Does your distro have ldconfig as part of the sytem? or did you just disable it as part of trying to speed things along? If it is still part of the sytem you can just run ldconfig as su to scan for shared libraries.

I had to remove ldconfig, because portage's sandbox didn't gave it permision to function, throwing an error. I could bypass this security mechanism, but I really mustn't - at least if linuxcnc is to become at last an official gentoo package.

And yes, ldconfig is ran at every startup or if the user requests it viaand the removal has nothing to do with speeding up the process - there wasn't any "process" and installation with it.

Last, I will follow your advise about the iso. It seems to be the most safe and legit way to find out. Thanks
