Gtk error messages

I get the following error messages when using InspectDR:

julia> include("test/plot.jl")
Gtk-Message: 12:00:41.791: Failed to load module "unity-gtk-module"
Gtk-Message: 12:00:41.810: Failed to load module "canberra-gtk-module"
Gtk-Message: 12:00:41.810: Failed to load module "canberra-gtk-module"

when running the script:

using Plots; inspectdr()

x=0:0.05:100
y1=sin.(x)
y2=cos.(x)

p1 = plot(x,y1, size=(640,480), legend=false)
p2 = plot(x,y2, size=(640,480), reuse=false, legend=false)
display(p1); p2

Any idea?

Using Ubuntu 18.04, Julia 1.7.3 and the following environment:

(KiteControllers) pkg> st
     Project KiteControllers v0.1.1
      Status `~/repos/KiteControllers/Project.toml`

I solved the issue by adding this line to .bashrc;

export GTK_PATH="/usr/lib/x86_64-linux-gnu/gtk-3.0:$PATH"

But why is it needed?

Uncertain. I know just about enough about Gtk to get InspectDR working.

Probably the reason Gtk works even this well is because of Julia's excellent BinaryBuilder.jl & Yggdrasil.jl package distribution system. 👍

I suggest you raise an issue with --> https://github.com/JuliaGraphics/Gtk.jl

Their team is much more knowledgeable than I am with respect to these issues.

You should be able to reproduce those error messages with a simple Gtk.jl program (taken from the Gtk docs):

using Gtk

win = GtkWindow("My First Gtk.jl Program", 400, 200)
b = GtkButton("Click Me")
push!(win,b)
showall(win)

Solution works.
