imshow() Gtk/.../GLib.jl:29 cfunction_ could not load library "libjulia"

[radonnachie]

Hello. A minimal example of: using Images, TestImages, ImageView; rgb_image = testimage("lighthouse"); imshow(rgb_image);

produces an error:

ERROR: error compiling cfunction: could not load library "libjulia" libjulia.so: cannot open shared object file: No such file or directory Stacktrace: [1] cfunction at /.julia/packages/Gtk/mVhmL/src/GLib/GLib.jl:29 [inlined] [2] signal_connect_generic(::Function, ::Gtk.GtkCanvas, ::String, ::Type{Nothing}, ::Tuple{}, ::Bool, ::Gtk.GtkCanvas) at /.julia/packages/Gtk/mVhmL/src/GLib/signals.jl:11 [3] signal_connect at /.julia/packages/Gtk/mVhmL/src/GLib/signals.jl:6 [inlined] (repeats 2 times) [4] Gtk.GtkCanvas(::Int64, ::Int64) at /.julia/packages/Gtk/mVhmL/src/cairo.jl:20 [5] (::getfield(GtkReactive, Symbol("##call#157#158")))(::Bool, ::Type{GtkReactive.Canvas{GtkReactive.UserUnit}}, ::Int64, ::Int64) at /.julia/packages/GtkReactive/YcoHq/src/graphics_interaction.jl:235 [6] Type at /.julia/packages/GtkReactive/YcoHq/src/graphics_interaction.jl:235 [inlined] [7] canvas at /.julia/packages/GtkReactive/YcoHq/src/graphics_interaction.jl:259 [inlined] (repeats 2 times) [8] frame_canvas at /.julia/packages/ImageView/Pi4jH/src/ImageView.jl:374 [inlined] [9] #imshow_gui#26(::String, ::Symbol, ::ImageView.SliceData{false,0,Tuple{}}, ::Function, ::Tuple{Int64,Int64}, ::Tuple{Int64,Int64}) at /.julia/packages/ImageView/Pi4jH/src/ImageView.jl:316 [10] #imshow_gui#31 at ./none:0 [inlined] [11] (::getfield(ImageView, Symbol("#kw##imshow_gui")))(::NamedTuple{(:name, :aspect),Tuple{String,Symbol}}, ::typeof(imshow_gui), ::Tuple{Int64,Int64}, ::ImageView.SliceData{false,0,Tuple{}}) at ./none:0 [12] #imshow#17(::Any, ::Any, ::Any, ::AbstractArray, ::Any, ::Reactive.Signal{GtkReactive.ZoomRegion{RoundingIntegers.RInt64}}, ::ImageView.SliceData, ::Any) at /.julia/packages/ImageView/Pi4jH/src/ImageView.jl:204 [13] #imshow at ./none:0 [inlined] (repeats 2 times) [14] #imshow#13(::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::AbstractArray) at /.julia/packages/ImageView/Pi4jH/src/ImageView.jl:179 [15] imshow(::AbstractArray) at /.julia/packages/ImageView/Pi4jH/src/ImageView.jl:176 [16] top-level scope at none:0

The 'libjulia' files were found: /usr/lib/x86_64-linux-gnu/libjulia.so.1 /usr/lib/x86_64-linux-gnu/julia /usr/lib/x86_64-linux-gnu/libjulia.so.1.0

As a temporary measure I tried creating some symlinks to the /usr/lib folder, but to no avail.

Any suggestions/queries?

Edited: provided further information on my amateurish attempts at resolving this.

How is Julia installed, via apt-get or by downloading julia binaries? Installing Julia using the system package manager is not very reliable and could cause similar issues

Can you verify that the same issue happens on Julia 1.3? There were some issues for Windows and MacOS for julia < 1.3, but it's still worth a try to see if it works for your situation.

I installed via apt-get.

I'll target the julia binaries (1.3) and respond.

Thanks

I installed via apt-get.

If you find installing Julia manually troublesome, you can try https://github.com/johnnychen94/jill.py

Working on Julia Version 1.3.1 (2019-12-30), and on Julia Version 1.0.5 (2019-09-09) when run from binary downloads (https://julialang.org/downloads/).

Thanks again

Edit: Confirmed v1.0.5 result.

Great, I'm closing it as it's not an ImageView issue.
