Magick.NET does not copy libraries to the correct location on macOS (or Linux)

See original GitHub issue

Magick.NET version

10.1.0

Environment (Operating system, version and so on)

macOS Big Sur 11.6.3

Description

Magick.NET does not copy libraries to the correct location on macOS (or Linux).

When running I get the following error:

Magick.NET-Q8-AnyCPU: The type initializer for 'ImageMagick.MagickFormatInfo' threw an exception.
Magick.NET-Q8-AnyCPU: The type initializer for 'NativeMagickFormatInfo' threw an exception.
Magick.NET-Q8-AnyCPU: Unable to load shared library 'Magick.Native-Q8-x64.dll' or one of its dependencies. 
In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable: dlopen(libMagick.Native-Q8-x64.dll, 1): image not found.

It can be solved by (with the output directory as current directory) copying runtimes/osx-x64/native/Magick.Native-Q8-x64.dll.dylib to bin/Magick.Native-Q8-x64.dll.

In my Azure Function Dockerfile that uses this library I have the following in the runtime image which solves the problem there:

RUN cp /home/site/wwwroot/bin/runtimes/linux-x64/native/Magick.Native-Q8-x64.dll.so \
	/home/site/wwwroot/bin/Magick.Native-Q8-x64.dll

This has been an issue for years now, it would be great if a real fix could be implemented. If the project maintainers do not wish to do this, please give me some pointers on where the logic that fixes this should be introduced and I’ll give it a whack.

Steps to Reproduce

Use the Magick.NET package on anything that isn’t Windows.

I should add an explanation about this to the documentation. You can now do the following in your .csproj file:

<Project>
  <PropertyGroup>
    <MagickCopyNativeLinux>true<MagickCopyNativeLinux>
  </PropertyGroup>
</Project>

And then it should copy the binaries.

Well I have issues on my Mac. I use this package in a subproject to an Azure Function, whenever I try to debug the Azure function using the Azure Functions runtime utilities I have to quickly copy the bin/output/runtimes/osx-x64/native/Magick.Native-Q8-x64.dll.dylib to the bin/output/ directory otherwise .NET doesn’t find it.
