Python Component - $PATH was created by zz912
Hello,

what is $PATH ???

make it executable (chmod +x), and place it on your $PATH

linuxcnc.org/docs/2.9/html/hal/halmodule.html

I am trying to make a python component according to the instructions. It's not working, any idea why?
Code:
jarda@CNC:~/linuxcnc/linuxcnc-2.9/configs/sim/gmoccapy/python$ ls passthrough  remap.py  stdglue.py  toplevel.py jarda@CNC:~/linuxcnc/linuxcnc-2.9/configs/sim/gmoccapy/python$ halrun halcmd: loadusr passthrough <stdin>:1: execv(passthrough): No such file or directory halcmd:

I use the more comfortable way, keep the component within /home/user/...  environment. Also good for backup of the configuration. In storage folder of component open terminal here, then:

sudo halcompile --install --userspace yourcomponent.py

To MaHa:

I tried your way, but it did not work.
Code:
jarda@CNC:~/Plocha$ halcompile --install --userspace passthrough.py jarda@CNC:~/Plocha$ halrun halcmd: loadusr passthrough halcmd: Traceback (most recent call last):   File "/home/jarda/linuxcnc/linuxcnc-2.9/bin/passthrough", line 2, in <module>     h = hal.component("passthrough")         ^^^ NameError: name 'hal' is not defined

I cannot use "sudo", because I have RIP instalation.

All info about is here and this worked for me:
linuxcnc.org/docs/stable/html/man/man1/halcompile.1.html

without root it might be difficult, but i don't know, as i have installed from .iso.

Did you set the RIP environment before running those commands?
Just a stab in the dark as i have not used RIP for over 5 years or more.

If I didn't use rip-environment, halrun wouldn't work.

I also didn't write that I use Debian Bookworm.
