Debuginfod is a service providing debug information over a HTTP API.

Installation

Install debuginfod.

Usage

ノート: debuginfod after version 0.186-3 adds DEBUGINFOD_URLS to the environment on login.

Set the environment variable which tells the tooling where to look for debug symbols:

export DEBUGINFOD_URLS="https://debuginfod.archlinux.org/"

One can also use https://debuginfod.elfutils.org/ which works as a federated server and queries all available debuginfod servers.

Now a debugger can fetch debug symbols without having to install the appropriate debug package.

$ gdb /usr/bin/i3

[...]
Reading symbols from /usr/bin/i3...
Downloading 1.56 MB separate debug info for /usr/bin/i3
Reading symbols from /home/user/.cache/debuginfod_client/29129d26dbe557d2b56daf90327f64f527304dc1/debuginfo...
(gdb)

See debuginfod-find(1) for usage.
