It is shared by rpm-pkg, deb-pkg, and pacman-pkg. https://github.com/torvalds/linux/blob/v6.12-rc5/scripts/package/install-extmod-build#L34 You will see how objtool is copied. (Anyway, it depends on your urgency. My hope is to support objtool and resolve_btfids in more generic ways.)

I will look into and likely bring a v2. I did not know about other distribution/package managers, if this is also a problem at them. At archlinux we have included this since a while already in the PKGBUILD, see here: https://gitlab.archlinux.org/archlinux/packaging/packages/linux/-/blob/main/PKGBUILD?ref_type=heads#L151-152 I will also make the change to grep for DEBUG_INFO_BTF in the config with the is_enabled function, instead of checking the path Regards, Peter

If the config is using DEBUG_INFO_BTF, it is required to, package resolve_btfids with. Compiling dkms modules will fail otherwise. Add a check, if resolve_btfids is present and then package it, if required. Signed-off-by: Peter Jung <admin@ptr1337.dev> --- scripts/package/PKGBUILD | 5 +++++ 1 file changed, 5 insertions(+)
