linuxcnc-uspace-dev is already the newest version (1:2.9.3).

It is already installed.
Should be something like:
sudo halcompile --install cia402.comp
But you need to be in the folder containing cia402.comp.

i'm not able to locate linuxcnc-dev folder as older version was available in same Home/linuxcnc-dev

Any ideas?

Seems to need homing.c file and it is not there, where and how did you get the files?
Good thing is the install command is working, proving LinuxCNC-dev is installed and working.

I just downloaded comp file from github. Can you guide me exact steps? Thanks in advance

Attached is a step by step pdf file that I use to install linuxcnc rip, The procedure assumes you have installed clean Debian 12 in your computer.
