July 1, 2020 - We pass the build ID of the target debuginfo file to debuginfod_find_debuginfo(). The function queries debuginfod servers for the file, and if it's successfully retrieved, a file descriptor and path of the local copy of the file are made available to GDB, which opens the file using the Binary File Descriptor (BFD) library and associates it with the corresponding object file that we are attempting to debug. Additionally, elfutils-based tools such as Systemtap automatically inherit debuginfod functionality from the elfutils debuginfod client.

The elfutils-debuginfod package contains the debuginfod binary and control files for a service that can provide ELF/DWARF files to remote clients, based on build-id identification.

We will present the elfutils debuginfo-server, where a web service offers a lightweight, build-id-indexed lookup of debuginfo-related data on demand. This service is designed to run on a nearby host, private or shared within teams, or even by ...

debuginfod is a web service that indexes ELF/DWARF debugging resources by build-id and serves them over HTTP. For more information see: https://sourceware.org/elfutils/Debuginfod.html

The elfutils-debuginfod-client package contains shared libraries dynamically loaded from -ldw, which use a debuginfod service to look up debuginfo and associated data.

January 26, 2026 - To improve ease of access to debugging resources, debuginfod servers are now being offered by various Linux distributions including Fedora, Ubuntu and Debian. These servers provide debuginfo, executable and source files from .rpm, .deb and .ddeb packages available from recent versions of these operating systems. See https://sourceware.org/elfutils...
