cubecamera error

[pbouffard]

Possibly just a beginner's mistake?

Same kind of issue with Makie

julia> Makie.Scene()
ERROR (unhandled task failure): MethodError: no method matching (::GLWindow.##23#24{Reactive.Signal{Tuple{Int64,Int64,Int64}}})(::GLFW.Window, ::Int32, ::GLFW.Action, ::Int32)

[SimonDanisch]

Oh, that happens because I import Base.Iterators: filter which was recommend in some deprecation warning... Jeez, so Base has actually now 2 filter functions, depending on the types?

After upgrade I still have a related (?) issue

julia> using GLVisualize, GeometryTypes
julia> window = GLVisualize.glscreen();
julia> mm = GLNormalMesh(Sphere{Float32}(Point3f0(0), Float32(1.)), 50);
julia> GLVisualize._view(GLVisualize.visualize(mm), window);
julia> GLVisualize.renderloop(window)

The sphere is displayed correctly but when I try to rotate it, the following error comes up

ERROR: MethodError: no method matching (::GLWindow.##23#24{Reactive.Signal{Tuple{Int64,Int64,Int64}}})(::GLFW.Window, ::Int32, ::GLFW.Action, ::Int32)

[SimonDanisch]

I can't reproduce this (as well as the Makie error). Can you give your Julia version + Pkg.status?

[edljk]

julia Version 0.6.2-pre.0, linux ubuntu,

julia> Pkg.status()
...
 - GLAbstraction                 0.6.1              master
 - GLFW                          1.5.0+             master
 - GLVisualize                   0.6.1+             master
 - GLWindow                      0.7.1              master
 - Makie                         0.0.0-             master (unregistered)
...

[SimonDanisch]

I have the same package version. Will try with julia 0.6.2 (I had 0.6.1 so far)

[SimonDanisch]

Ah, I can reproduce it - seems to be about glfw ( I actually wasn't on exactly the same version)

[SimonDanisch]

I get it..For the future, could you open new issues for unrelated problems? Your issue isn't about the filter changes, but since it's under the same issue, I assumed that ;)

GLFW is undergoing quite drastic changes... I'd suggest to just pin it to Pkg.pin("GLFW", v"1.4.1")
