programs like gdb.

Some NixOS packages provide debug symbols. However, these are
not included in the system closure by default to save disk
space. Enabling this option causes the debug symbols to appear
in <filename>/run/current-system/sw/lib/debug/.build-id</filename>,
where tools such as <command>gdb</command> can find them.
If you need debug symbols for a package that doesn't
provide them by default, you can enable them as follows:
<!-- FIXME: ugly, see #10721 -->
<programlisting>
nixpkgs.config.packageOverrides = pkgs: {
hello = overrideDerivation pkgs.hello (attrs: {
outputs = attrs.outputs or ["out"] ++ ["debug"];
buildInputs = attrs.buildInputs ++ [&lt;nixpkgs/pkgs/build-support/setup-hooks/separate-debug-info.sh>];
});
};
</programlisting>
'';
};
};
config = {
# FIXME: currently disabled because /lib is already in
# environment.pathsToLink, and we can't have both.
#environment.pathsToLink = [ "/lib/debug/.build-id" ];
environment.outputsToLink =
optional config.environment.enableDebugInfo "debug";
};
}
