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 {file}`/run/current-system/sw/lib/debug/.build-id`,
|
|
where tools such as {command}`gdb` can find them.
|
|
If you need debug symbols for a package that doesn't
|
|
provide them by default, you can enable them as follows:
|
|
|
|
nixpkgs.config.packageOverrides = pkgs: {
|
|
hello = pkgs.hello.overrideAttrs (oldAttrs: {
|
|
separateDebugInfo = true;
|
|
});
|
|
};
|
|
'';
|
|
};
|
|
|
|
};
|
|
|
|
|
|
config = mkIf config.environment.enableDebugInfo {
|
|
|
|
# FIXME: currently disabled because /lib is already in
|
|
# environment.pathsToLink, and we can't have both.
|
|
#environment.pathsToLink = [ "/lib/debug/.build-id" ];
|
|
|
|
environment.extraOutputsToInstall = [ "debug" ];
|
|
|
|
environment.variables.NIX_DEBUG_INFO_DIRS = [ "/run/current-system/sw/lib/debug" ];
|
|
|

};
