OSX M1, .NET Core 6 - Unable to load shared library 'libHarfBuzzSharp'

[jefim]

When trying to use any HardBuzzSharp (version 2.6.1.8) I am getting the following at runtime on my MacBook M1:

Unhandled exception. System.DllNotFoundException: Unable to load shared library 'libHarfBuzzSharp' or one of its dependencies. In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable: dlopen(liblibHarfBuzzSharp, 1): image not found
   at HarfBuzzSharp.HarfBuzzApi.hb_blob_create(Void* data, UInt32 length, MemoryMode mode, Void* user_data, DestroyProxyDelegate destroy)
   at HarfBuzzSharp.Blob.Create(IntPtr data, Int32 length, MemoryMode mode, ReleaseDelegate releaseProc) in HarfBuzzSharp.dll:token 0x600005f+0x10
   at HarfBuzzSharp.Blob..ctor(IntPtr data, Int32 length, MemoryMode mode, ReleaseDelegate releaseDelegate) in HarfBuzzSharp.dll:token 0x6000054+0x0
   at HarfBuzzSharp.Blob..ctor(IntPtr data, Int32 length, MemoryMode mode) in HarfBuzzSharp.dll:token 0x6000053+0x0
   at ConsoleApp1.Program.Main(String[] args) in /.../ConsoleApp1/ConsoleApp1/Program.cs:line 32

The same problem exists in e.g. SkiaSharp 2.80.3, but all works fine in SkiaSharp 2.88.0-preview61. The dlopen(liblibHarfBuzzSharp, 1) part looks fishy, but I have no idea what it could indicate. The lib itself is in the correct place (runtimes/osx/native/libHarfBuzzSharp.dylib).

My test program really does not do much, this is the code that crashes:

var face = new HarfBuzzSharp.Face(new Blob(IntPtr.Zero, 0, MemoryMode.Duplicate), 0);

Am I doing something wrong or is this a known issue? Any pointers appreciated!

2.80.3 has no native bits compiled for that arch so it is expected not to work properly

Is there anything I can do about it? Or is there any schedules or open issues that I can attempt to tackle for resolve this? Also, the 2.88 Skin package is fine for me, it is the HarfBuzzSharp that is causing the problem right now.

Let me have a look. I may not have pushed an update to harfbuzzsharp with the new architecture.

Hello, I have actually resolved this yesterday as I realized with help from others that I should be referencing SkiaSharp.HarfBuzz rather that directly HarfBuzz package. The SkiaSharp one actually does have this arch builtin and things are working. Thanks for the help.

If that is true there is something totally wrong. SkiaSharp.HarfBuzz only provides extension methods for HarfBuzzSharp and has no native assets.

I think I see what happened. I released SkiaSharp v2.80 and HarfBuzzSharp v2.6.1.8. This is the old combo. But, when 2.88 is coming around, the version that goes with that is HarfBuzzSharp v2.6.1.8-preview. I did not bump the HarfBuzzSharp version.

I see a 2.6.1.9 on the preview feed.

Basically, I forgot to bump harfbuzz when I released the preview, and when I did bump, it is still pending a release. I am waiting for the P7 of .NET 6 and .NET Maui.

Pulling in SkiaSharp.HarfBuzz 2.88 actually pulls in an "older" version, but is newer.

Just an FYI, I pushed a new preview of SkiaSharp and HarfBuzz and this should be good: https://www.nuget.org/packages/HarfBuzzSharp/2.6.1.9-preview.120

Also, it will have Mac Catalyst support.

Thanks for the explanations! I think that this is now resolved.
