init_deps not found when imagemagick is already installed on OSX

[rened]

Using 0.4 and the currently tagged versions of Images and ImageMagick I get the following error at using ImageMagick.

WARNING: Method definition writemime(Base.IO, Base.Multimedia.MIME{:image/png}, Images.AbstractImage) in module Images at /Users/rene/.julia/v0.4/Images/src/io.jl:216 overwritten in module ImageMagick at /Users/rene/.julia/v0.4/ImageMagick/src/ImageMagick.jl:276.

The same happens when using the latest checkouts of both packages.

Note that in both cases I have the imagemagick library already installed through "brew install imagemagick", i.e. outside of Julia.

When I uninstall the package from my homebrew installation and run Pkg.build("ImageMagick"), Homebrew.jl installes the dependencies and from then on Images and ImageMagick work.

init_deps is missing because of the issue, that BinDeps doesn't include the load hooks when the library is already present.
@staticfloat, was there a solution for this?
ImageMagick doesn't go with the currently tagged Images version, if I haven't missed anything ;)
We should have resolved the last issues and @timholy wanted to go tagging after this is resolved:
JuliaMath/FixedPointNumbers.jl#27

[staticfloat]

The Homebrew hook will not be run if the binaries aren't coming from Homebrew.jl (which is the case when you already have binaries available on your system).

I believe to have a preload hook for SystemPaths-satisfied binaries, we are going to need to find some way to attach those preload hooks to the SystemPaths provider via BinDeps. @Keno do you think this is possible via something like provides( SystemPaths, "libwand", preload = ... )?

I also see this issue on Centos 7 with system installed ImageMagick. Is there a short-term fix?

[SimonDanisch]

Can you post the contents of Images/deps/deps.jl?

[SimonDanisch]

thanks! So it does actually have the correct path in there.
I guess I don't really understand the purpose of the hooks and why they're missing in that case.
Maybe we should just stop using the hooks and move them into ImageMagick, since the path is all we need.
You should be able to temporarily fix this by putting this into deps.jl:

function init_deps()
    ccall((:MagickWandGenesis,libwand), Void, ())
end

I'll probably need to wait for a real fix, as I want to use it for doing integration testing on travis. See: JuliaPlots/Plots.jl#38. Though I suppose I could fork, make the change, and point travis to the fork...

I am running into this too on a Centos machine...

julia> BinDeps.debug("ImageMagick")

If someone is watching and wants to quickly test #14, that would be great. But if CI passes I'll merge and tag (hopefully in a few minutes), since it's not good to have the UFixed incompatibility around any longer than necessary.
