Error while building on Raspberry Pi OS (Bookworm)

[S0lmyr]

Hello, I am successfully running gpio-ts with f007th-rpi on previous version of Raspberry OS (11 Bullseye) Hovever I want to upgrade it to Bookworm.

So I made fresh installation of Bookworm.

Now, I'm running 64bit version of Rasbian OS (Bookworm)

I've installed kernel headers sudo apt install linux-headers-rpi-v8 my version is now: 6.6.28+rpt-rpi-v8

However, when I tried to run make all on gpio-ts I have some issues:

make -C /lib/modules/6.6.28+rpt-rpi-v8/build M=/home/pi/gpio-ts modules

Can someone help me please?

Same error for me

[phueper]

i seem to have fixed this for me in #2 ... but i also had to adapt the MAX_GPIO in f007th-rpi, if you also use that, you might also need to do that ... for me now my temp sensors are working again, and i'm happy :)

Hello Patrick,

thank you for sharing your fix. It is working for me either. I was a little bit confused where to edit MAX_GPIO, but made it. Thank you again!
