[BUG] Native library missing on Xamarin.Mac Full #913

Closed Odirb closed 5 years ago

Odirb commented 5 years ago

Description

Application crash on SKBitmap creation with a DllNotFoundException in inner exception :

System.TypeInitializationException: The type initializer for 'SkiaSharp.SKImageInfo' threw an exception. ---> System.DllNotFoundException: libSkiaSharp at at (wrapper managed-to-native) SkiaSharp.SkiaApi.sk_colortype_get_default_8888() at SkiaSharp.SKImageInfo..cctor () [0x00000] in :0 --- End of inner exception stack trace --- at at (wrapper managed-to-native) System.Object.__icall_wrapper_mono_generic_class_init(intptr) at SkiaSharp.SKBitmap..ctor (System.Int32 width, System.Int32 height, System.Boolean isOpaque) [0x00000] in :0 at TestSkia.MainClass.Main (System.String[] args) [0x00001] in /Users/christophe/Projects/TestSkia/TestSkia/Main.cs:10

Code `namespace TestSkia { static class MainClass { static void Main(string[] args) { new SKBitmap(10, 10);

        NSApplication.Init();
        NSApplication.Main(args);
    }
}

} `

Expected Behavior

Output directory should contains libSkiaSharp.dylib (native Skia library for OSX)

Actual Behavior

Output directory contains x86/libSkiaSharp.dll and x64/libSkiaSharp.dll, which are native library for Windows and not OSX

I believe this is a duplicate of https://github.com/mono/SkiaSharp/issues/736

You can add <MigrateToNewXMIdentifier>true</MigrateToNewXMIdentifier> in your project.

Odirb commented 5 years ago

Thanks for you response Matthew, But when I add MigrateToNewXMIdentifier to my project it cannot be loaded by Visual Studio (I'm using the latest VS for Mac 2019 - version 8.1.5 build 9).

I have extracted the exception from ~/Library/Logs/VisualStudio/8.0/Ide.2019-07-22__09-01-53.log file :

Since VS for Mac is not ready to target Xamarin.Mac.NET yet, I will use this ugly workaround for now: add the libSkiaSharp.dylib in my main project as "Content". The library will be copy in bundle after compilation in the correct folder to be loaded by SkiaSharp.dll

mattleibow commented 5 years ago

It is a tad bit disappointing. But the workaround to add the .dylib should do it for the time being. I'll have a look at the targets file - I may be able to tweak a few lines to copy this in if it detects the full framework.

Just a link to the info about the support: https://github.com/NuGet/NuGet.Client/pull/2572#issuecomment-514103636
