Error during install on rpi4 bookworm Linux kernel 6.12, how to solve ? (SOLVED!)

[sledgemhammer]

Error during install.sh:

make -j4 KERNELRELEASE=6.12.25+rpt-rpi-v8 -C /lib/modules/6.12.25+rpt-rpi-v8/build M=/var/lib/dkms/wm8960-soundcard/1.0/build.....(bad exit status: 2)
Error! Bad return status for module build on kernel: 6.12.25+rpt-rpi-v8 (aarch64)
Consult /var/lib/dkms/wm8960-soundcard/1.0/build/make.log for more information.
Job for wm8960-soundcard.service failed because the control process exited with error code.
See "systemctl status wm8960-soundcard.service" and "journalctl -xeu wm8960-soundcard.service" for details.

tried the earlier post ( https://github.com/HinTak/seeed-voicecard/tree/v6.12) and reinstalled after that with still same error

For anyone searching this the solution for me is : https://github.com/ubopod/WM8960-Audio-HAT

so use :
git clone https://github.com/ubopod/WM8960-Audio-HAT
in place of the original instructions. For the rest follow the original instructions can be followed.
Using this it works instantly.

p.s. if you have started installing the original, remove it first ...

@sledgemhammer thaaaaaaaaaaaaaanks ! you saved my WE ! I was tearing my hair out... ChatGPT was telling me it was the kernel version that wasn't compatible. And I saw your post in Solved with the same kernel version. install.sh put an error message at the end, but everything is OK... I successfully completed a voice recording test.
Thank you, thank you.
