linuxcnc-dev is missing?

EDIT:
Ignore this post, Benb pointed to info i missed, sorry.

This is not about installing RIP, it is about installing EtherCAT modules.

Download the whole project, not just the file you need, and try again.

Hey Tom, I am complete dummy when it comes to Linux OS. ?However, since I started using RIP I know where all pieces of the programs I loaded reside. For non linux savey it makes it easy to troubleshoot. As marq_torque indicated he does not know the location of hos files. marq_torque Once you install rip all your linux files will reside in Linuxcnc directory. If you follow the procedure all your linuxcnc files will reside in /dev/linuxcnc.

Sorry Benb, my bad, i just noticed it is looking for the homing.c file in the dev folder.
Thank you for bringing that to my attention, very much appreciated.
