Pkg.test failing about glvisualize.jl HOT 4 CLOSED

This is actually an error in ImageMagick! You can ignore it, if you don't plan to load images.
The error is surprising though, since this was fixed at some point.
Did you already have an ImageMagick installation on your computer, before adding GLVisualize?
Maybe because of earlier versions of Images.jl?

from glvisualize.jl.

Ahh looks to be an error with ImageMagick, I pulled the latest master (I already had ImageMagick installed on my PC in program files folder)

julia> Pkg.build("ImageMagick")

from glvisualize.jl.

Have you tried removing it and then Pkg.add("ImageMagick");Pkg.build("ImageMagick")
So far, I was able to ignore the error above, and it still worked for me.

from glvisualize.jl.

Yes I have, the output of the error is shown above.

I have tested on a new commit on master and on v0.4, in both cases I get the same error, however, I cannot ignore the errors since it basically crashes the script, i.e. no output.

EDIT:

Error identified. First if you already have ImageMagick in path before installing ImageMagick.jl, you have to first make sure you remove it from path (probably also safe to move it to load after julia environment variable is loaded). Then it will work if you call Pkg.build("ImageMagick") despite still showing the error
