Hello, I can confirm that with the dwarves package in proposed (1.21-0ubuntu1~20.04) I can successfully build the Ubuntu mainline kernel from source (tested version 5.13.19) using git commit from: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.13.19/
When using the version of dwarves currently in focal (1.15-2) the build fails with: AR drivers/gpu/built-in.a AR drivers/built-in.a GEN .version CHK include/generated/compile.h LD vmlinux.o MODPOST vmlinux.symvers MODINFO modules.builtin.modinfo GEN modules.builtin BTF: .tmp_vmlinux.btf: pahole version v1.15 is too old, need at least v1.16 Failed to generate BTF for vmlinux Try to disable CONFIG_DEBUG_INFO_BTF make[2]: *** [/home/source/Makefile:1216: vmlinux] Error 1 make[2]: Leaving directory '/home/source/debian/build/build-generic' make[1]: *** [Makefile:220: __sub-make] Error 2 make[1]: Leaving directory '/home/source' make: *** [debian/rules.d/2-binary-arch.mk:53: /home/source/debian/stamps/stamp-build-generic] Error 2 dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912811 Title: Update dwarves-dfsg in focal to version 1.21 from impish To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dwarves-dfsg/+bug/1912811/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
