Error building custom kernel

[Joly0]

Hey, i have tried building the custom kernel with this command "sudo make -j 8 && sudo make modules_install -j 8 && sudo make install -j 8" but i get the following output:

Any idea why the error "FAILED: load BTF from vmlinux: Unknown error -22make: *** [Makefile:1179: vmlinux] Error 255" appears here? I tried googling it, but i havent found anything useful

Depending on which additional drivers you enabled, you may have to install additional developer packages. The instructions on https://github.com/dorssel/usbipd-win/wiki/WSL-support#building-your-own-usbip-enabled-wsl-2-kernel are just for the default kernel configuration.

Which additional CONFIG_XXX did you add?

a sudo apt install dwarves should resolve it, then re run the compilation
