Shutter crashes on startup on NixOS #486

Open refaelsh opened 2 years ago

refaelsh commented 2 years ago

I use NixOS. Version: 0.99.2 Rev.1593. Here is the error when I run shutter:

Help please :-)

I think, this is the point, when @DarthGandalf should have a look. :smiley:

refaelsh commented 2 years ago

@DarthGandalf can you please take a look?

I'm back from vacation.

These <optimized out> break everything, any way to avoid such optimization?

Script to build and launch VM:

Due to nixos-rebuild, it looks like it requires using nixos already?

I'm back from vacation.

These <optimized out> break everything, any way to avoid such optimization?

I'm testing with adding this to the configuration.nix file (of the VM):

  nixpkgs.overlays = [
    (final: prev: {
      glib = prev.glib.overrideAttrs (old: {
        dontStrip = true;
        NIX_CFLAGS_COMPILE = (old.NIX_CFLAGS_COMPILE or "") + " -ggdb -Og";
      });
    })
  ];

but it causes lots of rebuilding. (glib is pretty deep in the dependency graph. I commented out firefox from configuration.nix to at least not have to rebuild that.)

Script to build and launch VM:

Due to nixos-rebuild, it looks like it requires using nixos already?

Actually, no. nixos-rebuild is available by default in NixOS systems (so I forgot that it was an implicit/undeclared dependency in my script), but you can also get it on any other Linux system that has Nix. In the "Script to build and launch VM" I posted, you can replace the last line with these two lines:

nixos_rebuild=$(nix-build -A nixos-rebuild "<nixpkgs>")
"$nixos_rebuild/bin/nixos-rebuild" build-vm && SHARED_DIR="$shared_dir" ./result/bin/run-nixos-vm -m 4096

Latest backtrace, now with glib built with -ggdb -Og:

Unfortunately, there's still some <optimized out>, but somewhat fewer than last time.

Another gdb backtrace of the shutter startup segfault, now with glib compiled with -O0 instead of -Og, which exposes the last optimized outs. (There are two optimized out variables left from GTK since I didn't build it with debugging.)
