UndefVarError: libwand not defined on Julia 1.7 macOS ARM (M-series Processor) but not earlier Intel versions

[disleyland]

I'm getting this undefvarerror on using ImageMagick, and it is only happening on Julia 1.7 ARM version, not the Julia 1.6.3 Intel version also running on the same computer.

InitError: UndefVarError: libwand not defined

I had the same issue on a Macbook air M1 using Julia 1.7.1 (installed via homebrew). I checked the version of ImageMagick_jll and it was 6.9.10. I checked

https://github.com/JuliaBinaryWrappers/ImageMagick_jll.jl/tree/main/src/wrappers

and it seems that the latest version has wrapped 'aarch64-apple-darwin'. Maybe 6.9.10 didn't have this?

Updating the ImageMagick_jll seems to solve the problem for me. In package mode I ran add ImageMagick_jll@6.9.12.

Updating the ImageMagick_jll seems to solve the problem for me. In package mode I ran add ImageMagick_jll@6.9.12.

Unfortunately, the problem resurfaced and now it fails also with 6.9.12.

I had this problem on:

ImageMagick_jll v6.9.10-12+3
ImageMagick v1.2.2

There are still a few cases that we need ImageMagick.jl, but we might eventually sunset this package in favor of ImageIO; if everything moves smoothly we'll have a GSoC project adding three more formats to ImageIO: JuliaImages/Images.jl#1000

[disleyland]

is a "readblob" implementation one of those few cases where ImageMagick.jl is needed? Or is there an alternative route for saving a blob (in the form of a Vector{UInt8}) as a file via FileIO?

Here is a notebook file to reproduce the problem:

I see this issue is closed, but I'm confused about how to solve this problem. I need ImageMagick to save a vector of plots as a GIF (FileIO asked for QuartzImageIO, which asked for ImageMagick). Is there any way of saving as .gif without having to use ImageMagick?

NB: The error only appears the first time I run using ImageMagick. If I run it again the issue does not appear and everything works... It's just a bit annoying

Let's leave it open until fully resolved.

Fixed in 1.3.1
