18 debuginfod

debuginfod is a web service that indexes ELF/DWARF debugging resources by build-id and serves them over HTTP.

Binutils can be built with the debuginfod client library libdebuginfod using the --with-debuginfod configure option. This option is enabled by default if libdebuginfod is installed and found at configure time. This allows objdump and readelf to automatically query debuginfod servers for separate debug files when the files are otherwise not found.

debuginfod is packaged with elfutils, starting with version 0.178. You can get the latest version from ‘’.
