Hi, I’m trying to build a gui using julia.  
I am running this on ubuntu 20.04

I have a module called TEST  
TEST/src/TEST.jl code:

```julia
module TEST
using Gtk

export real_main, julia_main

const win = Ref{GtkWindow}()
const img = Ref{GtkImage}()

function julia_main()::Cint
    try
        real_main()
    catch
        Base.invokelatest(Base.display_error, Base.catch_stack())
        return 1
    end
    return 0
end

function real_main()
    cd(@ __DIR__ )
    println(abspath("../data/logo.png"))

    win[] = GtkWindow("Crystal Chess", 800, 800)
    img[] = GtkImage(abspath("../data/logo.png"))

    push!(win[], img[])
    showall(win[])

    readline()
end
end # module

```

I got this error after running the compiled file

```julia

This should be reported as an issue at some of the packages. What do you think @giordano is that a PackageCompiler.jl issue, a Gtk.jl issue or an issue with BB?

I’d first try to asses whether this works without PackageCompiler.

Sorry for replying so late!  
I forgot to add that I get this warning no matter if I compiled it or not:

```julia
Gtk-Message: 21:10:46.965: Failed to load module "canberra-gtk-module"
Gtk-Message: 21:10:46.968: Failed to load module "canberra-gtk-module"

```

This works when not compiled but doesn’t work when it is.

Those warnings are totally harmless, you can ignore them

Maybe @kristoffer.carlsson has some ideas?

Those are harmless but still annoying. If you search it online you’ll see how to fix it. It just means you are missing some gtk pieces that it wants.

Can you tell us how to fix the warnings? That would be awesome, there is also an issue open in Gtk.jl

Like I said, I just googled the error message. For the error message above, it seems that doing

```bash
sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

```

might fix the issue. When I got the error messages, it was actually complaining about a different module, so I think there must be something related to the system installation which likely differs across distros.
