elfutils debuginfod is a client/server in elfutils 0.178+ that automatically distributes elf/dwarf/source-code from servers to clients such as debuggers across HTTP.


Anyone may run debuginfod servers for their private purposes. Software publishers are invited to run public servers for use by the community. Heck, anyone may run servers based on redistributable artifacts from others. To configure a client tool to use them, simply add any of the server URLs to your $DEBUGINFOD_URLS environment variable (space-separated).

private servers

To run your own server, identify the directories containing raw build files, or RPM packages, or DEB packages, or any combination, plus any desired upstream federated servers. Launch debuginfod into the background, or use systemd.
% export DEBUGINFOD_URLS=https://foo.bar/   # list of federated upstream servers, if any
% debuginfod [-F $files] [-R $rpms] [-U $debs] &
Then, configure clients to talk to this server:
% export DEBUGINFOD_URLS=http://localhost:8002/

public servers

The following public services currently [2023-03] welcome users.
The first one federates to others, so
% export DEBUGINFOD_URLS="https://debuginfod.elfutils.org/ $DEBUGINFOD_URLS"
% export DEBUGINFOD_PROGRESS=1    # for optional download progress reporting
will get you to most of them. If your distro offers a server, you may prefer to link to that one directly, for authoritative service.
