Raspberry pi 5

  I am install linuxcnc 2.9.2 on raspberry pi5  and  I am  completing all  setting for Linux cnc lathe then I started linuxcnc and I found error and error picture I am also attached please see and guide me how to solve this problem 

As per:
linuxcnc.org/docs/html/drivers/hal_pi_gpio.html
7. Known Bugs

At the moment (2023-07-16) this driver only seems to work on Raspbian as the generic Debian image does not set up the correct interfaces in /dev/gpiomem and restricts access to the /sys/mem interface.

Thanks for reply sir please tell now what is solution of this problem

 Thanks for reply sir i am attached error please see

The error is
HAL_PI_GPIO: can't open /dev/gpiomem: 2 - No such file or directory

/dev/gpiomem doesn't exist

So have will have to start with a Raspbian image, build & install a rt kernel and then build & install linuxcnc.

But just for completeness can you run
and report the result

This problem was already known:

My advice is to use this new module (hal_gpio) which, in addition to working on Pi 5, in my opinion is more versatile and easier to configure

For changes to be made to .hal files it may be useful to refer to this video

Many thanks.
