13 Some NixOS packages provide debug symbols. However, these are
14 not included in the system closure by default to save disk
15 space. Enabling this option causes the debug symbols to appear
16 in <filename>/run/current-system/sw/lib/debug/.build-id</filename>,
17 where tools such as <command>gdb</command> can find them.
18 If you need debug symbols for a package that doesn't
19 provide them by default, you can enable them as follows:
20 <!-- FIXME: ugly, see #10721 -->
21 <programlisting>
22 nixpkgs.config.packageOverrides = pkgs: {
23 hello = overrideDerivation pkgs.hello (attrs: {
24 outputs = attrs.outputs or ["out"] ++ ["debug"];
25 buildInputs = attrs.buildInputs ++ [<nixpkgs/pkgs/build-support/setup-hooks/separate-debug-info.sh>];
26 });
27 };
28 </programlisting>
29 '';
30 };

42 optional config.environment.enableDebugInfo "debug";
