Minimum gLibC version required (2.34) is not available for Raspberry Pi OS

[VoidJuiceConcentrate]

In trying to call pwmFanControl64 directly, I get the following error:

pwmFanControl64: /lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by pwmFanControl64)

Yet, the highest available (stable) version of gLibC is 2.31, from official Debian/RaspberryPi OS sources.

Tool needs to be built with gLibC 2.31 compatibility.

Functionality is... spotty at the moment. Sometimes setting custom temperature and fan speeds works and sometimes it doesn't, this includes the default/number 7 option. Fan doesn't seem to respond to changing CPU temp outside of when initially set by the command deskpi-config.

Hi @VoidJuiceConcentrate,

Yet, the highest available (stable) version of gLibC is 2.31, from official Debian/RaspberryPi OS sources.

For your sake I hope it does not. Debian Bookworm itself is at 6.1.4 (and still counting up as we speak)

Did you by any chance cross compiled those tools or used another version of Raspi OS to compile them ?

[VoidJuiceConcentrate]

No, there shouldn't be any cross compiled tools. (I try to keep any cross-compilation docker-containerized)

pi@rpi4:~ $ uname -a
Linux rpi4 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux

libc6 is already the newest version (2.31-13+rpt2+rpi1+deb11u10).

Not sure how to proceed here.

Can you acknowledge that you are running Raspi OS bullseye ?

This is my setup:

If you are running Bullseye then the utilities pwnControl64 and safeCutOffPower64 are required to be compiled manually see also https://github.com/DeskPi-Team/deskpi/blob/master/installation/drivers/README.md

Another possible solution is to update your current installation.

I did try to recompile them following the instruction inside, but the same error occurs on the newly built files.

Nigh impossible when you build the tools on/for a bullseye system.

After compilation of the tools and after downloading the installation repository the files in the driver/c directory need to be replaced with those that were manually build. Then the installation script install-raspios-64bit.sh can be run.
