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 = pkgs.lib.overrideDerivation pkgs.hello (attrs: {
|
|
outputs = attrs.outputs or ["out"] ++ ["debug"];
|
|
buildInputs = attrs.buildInputs ++ [<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.extraOutputsToInstall =
|
|
optional config.environment.enableDebugInfo "debug";
|
