Hi,
I setup ECI apt repo, installed linux-intel-rt and ighethercat, things work, but headers seem to be in wrong location, and lib symlink seems to be missing. It looks like the installation didn't finish correctly. I do see an error during my installation, but I don't know if it is related.
headers are located in: /usr/src/ighethercat-dkms-1.5.2/include/ , this seem to be a source code location (which I have to add to header file search path, and Makefile template doesn't mention this location at all)
gf@gf-cst-i5-2:/$ sudo find -name ecrt.h
./usr/src/ighethercat-dkms-1.5.2/include/ecrt.h
...
libs are located in: /usr/lib/x86_64-linux-gnu/, but no symlink with name libethercat.so exist, so I had to create that for my linker to be able to find the library.
gf@gf-cst-i5-2:/$ sudo find -name libethercat.*
./usr/lib/x86_64-linux-gnu/libethercat.so.1.0.0
./usr/lib/x86_64-linux-gnu/libethercat.so.
...
I see this during my installation:
gf@gf-cst-i5-2:~$ sudo apt install ighethercat ighethercat-dkms ighethercat-examples ecat-enablekit
...
depmod...
Building initial module for 6.5.0-27-generic

I setup ECI apt repo, installed eci-customization, linux-intel-rt and ighethercat following these pages:

Hi,
could you share the error that you encountered when installing too (which you mentioned)?
Perhaps this is related to your network, did you try to re-install using a different network?
Cordially,
Iffa

Hi,
Thank you for your question. If you need any additional information from Intel, please submit a new question as Intel is no longer monitoring this thread.
Cordially,
Iffa
