Hello Everyone, I tried to compile cia402.comp Homing.comp and for that Linuxcnc-Dev is necessary. i tried to install but got following errors

Pl ignore my mistakes, i'm not understanding how linuxcnc-dev installation works.

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

Any ideas?

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.
 

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.
