Looking at the FreeBSD headers it appears they define Elf_Note not Elf_Nhdr. https://svnweb.freebsd.org/base/head/sys/sys/elf_common.h?revision=HEAD&view=co The OpenBSD headers define both at the moment to be compatible though the Elf_Note members on OpenBSD do not have the n_ prefix only the Elf_Nhdr structs do where as the FreeBSD Elf_Note has the n_ prefix. Build error introduced with this commit. commit d4fa083e11fa71abd50e615d6f02b6da4ea34644 Author: Matt Turner <mattst88@gmail.com> Date: Tue Feb 14 07:29:56 2017 -0800 util: Add utility build-id code. Provides the ability to read the .note.gnu.build-id section of ELF binaries, which is inserted by the --build-id=... flag to ld. Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Chad Versace <chadversary@chromium.org> Quick search showed the following handy website. In there you can see that things "broke" between FreeBSD 10 and 11 - former has Elf_Nhdr while latter does not. Not sure how to solve this - anyone having a platform like that feel free to send a patch to the mailing list :-) http://fxr.watson.org/fxr/ident?v=FREEBSD10;i=Elf_Nhdr Vinson do check the said site. Alternatively you can see/work with the FreeBSD people - they seems to have some partial solution there [1] [1] https://github.com/freebsd/freebsd-ports-graphics/blob/master/graphics/mesa-dri/files/patch-src_util_build__id.c -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
