The build-id note (.note.gnu.build-id) is in both the original ELF file and in the .debug file. The note is also marked as SHF_ALLOC so that it appears in the executable image, and should be put in the core file when dumped. See http://fedoraproject.org/wiki/Releases/FeatureBuildId for an overview. A simple way to get the build-id(s) is through eu-unstrip (part of elfutils). build-id from an executable, shared library or separate debuginfo file: $ eu-unstrip -n -e <exec|.sharedlib|.debug> build-ids of an executable and all shared libraries from a core file: $ eu-unstrip -n --core <corefile> build-ids of an executable and all shared libraries of a running process: $ eu-unstrip -n --pid <pid> Cheers, Mark _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
