Skipping BTF Generation due to unavaliablity of vmlinux #33

I got the error below while building the repo on Fedora 38.

[erhangk@fedora acer-wmi-battery]$ make make -C /lib/modules/6.4.14-200.fc38.x86_64/build M=/home/erhangk/acer-wmi-battery modules make[1]: Entering directory '/usr/src/kernels/6.4.14-200.fc38.x86_64' CC [M] /home/erhangk/acer-wmi-battery/acer-wmi-battery.o MODPOST /home/erhangk/acer-wmi-battery/Module.symvers CC [M] /home/erhangk/acer-wmi-battery/acer-wmi-battery.mod.o LD [M] /home/erhangk/acer-wmi-battery/acer-wmi-battery.ko BTF [M] /home/erhangk/acer-wmi-battery/acer-wmi-battery.ko Skipping BTF generation for /home/erhangk/acer-wmi-battery/acer-wmi-battery.ko due to unavailability of vmlinux make[1]: Leaving directory '/usr/src/kernels/6.4.14-200.fc38.x86_64'

When i try to turn on health mode sometimes it just works and enable it but sometimes i get this error:

tee: /sys/bus/wmi/drivers/acer-wmi-battery/health_mode: No such file or directory

I don't know if it is because of Fedora or vmlinux, is there any fix about this?

Just do the following commands before making if you are using ubuntu linux.

sudo apt -y install dwarves
sudo cp -avi /sys/kernel/btf/vmlinux /usr/lib/modules/`uname -r`/build/
