Setting up Makie on Mac

I had the same problem as this guy (https://discourse.julialang.org/t/no-backend-available-glmakie-cairomakie-wglmakie/62984) with Makie, so I decided to try just GLMakie to figure out what’s going on.

These are my steps, and relevant outputs in the order I performed those. (I’m on a 2016 MBP, with macOS Catalina)

  1. pkg> add GLMakie
    Precompiles successfully.

  2. pkg> test Makie

  2. pkg> st ReferenceTests

At this point, I’m not sure what to do next

  1. However I ran the following code segment on Juno (Atom)
using GLMakie

inline!(false)

scene = Scene()


points = [Point2f0(cos(t), sin(t)) for t in LinRange(0, 2pi, 20)]
colors = 1:20
scatter!(scene, points, color = colors, markersize = 15)

everything ran without any issues, however, the output is only a white canvas (displayed at the line scene = Scene() ).

  1. I read somewhere that I may need to build GLMakie, so I did that by pkg> build GLMakie
    Building ModernGL → `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/326957556e9cc9253615114c04bb0096a2a69bb8/build.log`
Precompiling project...
  2 dependencies successfully precompiled in 9 seconds (155 already precompiled)
  1. Trying code in (7) again. - same result.

I should note that scatter!(...) returns Scatter{Tuple{Vector{Point{2, Float32}}}}, while the documentation at https://juliahub.com/docs/AbstractPlotting/6fydZ/0.14.1/basic-tutorial.html states the following:

Scene (960px, 540px):
  2 Plots:
    ├ Combined{AbstractPlotting.axis2d,Tuple{Tuple{Tuple{Float32,Float32},Tuple{Float32,Float32}}}}
    └ Combined{AbstractPlotting.scatter,Tuple{Array{Point{2,Float32},1}}}
  1 Child Scene:
    └ Scene (960px, 540px)

which I do not get.

I’m unsure how to proceed from here. Could someone please give a hint on what I can try next.

Thank you!

you are not up to date with the syntax. Plus, the documentation link that your are using is outdated. You should use this one.
