Similar story to: veldrid/veldrid#24 (comment)

Running with mono on mac, and I'm getting:

Worked around it for now by copying the file manually from
~/.nuget/packages/veldrid.spirv/1.0.7/runtimes/osx-x64/native/libveldrid-spirv.dylib

[mellinoe]

Something like this file is needed for mono to work automatically:

https://github.com/mellinoe/veldrid/blob/master/src/Veldrid.SDL2/build/net40/Veldrid.SDL2.targets

[mellinoe]

I included a build targets file in the latest version (1.0.8) that should fix this.

[tzachshabtay]

@mellinoe this doesn't seem to work. I'm now getting a compile error:

/Library/Frameworks/Mono.framework/Versions/5.16.1/lib/mono/msbuild/15.0/bin/Microsoft.Common.CurrentVersion.targets(5,5): Error MSB3030: Could not copy the file "/Users/zachi/.nuget/packages/veldrid.sdl2/4.5.0/runtimes/osx-x64/native/libveldrid-spirv.dylib" because it was not found. (MSB3030) (MonoQuad)

For some reason it seems to try finding the spirv dylib in the sdl2 directory?

[mellinoe]

It looks like your NuGet package somehow got messed up. Can you delete the /Users/zachi/.nuget/packages/veldrid.sdl2/ folder and then run restore again (it will be downloaded again). If that doesn't help, please share your project so I can repro it.

[tzachshabtay]

Doesn't help.
Try compiling the MonoQuad project in this branch (on mac).

[mellinoe]

@tzachshabtay Sorry about this, there's definitely a problem with how Veldrid.SDL2 and Veldrid.SPIRV interact when they are both referenced from a mono project. Additionally, there's a problem with Veldrid.SDL2 4.5.0 that has been fixed in 4.6.0 that interferes with osx-x64 detection.

The root problem is that both NuGet packages try to define the same _NativeLibName property (and a couple of other "private" properties), and they end up colliding with each other when referenced by the same project. This is why it is seemingly looking for libveldrid-spirv.dylib in the SDL2 package directory. I'll prepare a fix and put out a patch for the NuGet packages so there are no collisions.

[mellinoe]

Veldrid.SDL2 4.6.1 and Veldrid.SPIRV 1.0.9 both include fixes to ensure that they won't cause build property collisions anymore. Upgrading one or both should solve your issue. Sorry for the slow fix here; please let me know if anything else is not working correctly.

[tzachshabtay]

I can confirm that it's working properly now, thank you.

I'm still facing this issue. I'm using Rider on mac.

I worked around by copying the .dylib from the .nuget directory.
