Hallo Daniel,
that sounds like the ethercat library does not fit to the kernel module.
If you have installed the two ethercat installations to different
locations e.g. /usr/lib or /usr/local/lib it is depending on your search
path settings what gets found first.
So it might be helpful to clean up first and do a fresh ethercat install.
Regards Wilhelm

Hi
Im having trouble starting the build application from Matlab. Ethercat
recognizes all the slaves and the master seems operational. However when
I try to run the built executable I get the following error.
/Failed to request master 0: Inappropriate ioctl for device/
This started happening after I updated my Ethercat installation (I went
from downloading the tar file to clone it using hg).
I see there is an old post discussing this topic
(http://lists.etherlab.org/pipermail/etherlab-users/2009/000437.html)
but there is no clear solution (Or at least not clear to me) on how this
issue could be solved. In this post It is suggested that the problem is
caused by an old master module loaded when a new library version is
used. To be honest I don’t know how to solve this.
I appreciate the help you guys could give me
Daniel Lemus
