[QUESTION] How to correctly package SkiaSharp for Installer on Windows VS #2463

Open erebuswolf opened 1 year ago

erebuswolf commented 1 year ago

I have a WPF app that I added a SkiaSharp control to for high performance drawing. It works great. Runs fine in Visual Studio. It runs fine when I build and open the exe in the build output folder. But when I package an installer and try running the installed application, I get this error:

I've been searching trying to determine the source of the issue. I installed Skia vis the NuGet installer for the project. The following dlls are included as dependencies in the installer:

I can see the dlls are in the application directory for the installed application.

The dlls have the following attributes for the installer: DLL config

Any help is appreciated. I put a lot of work rewriting my applicaiton to use SkiaSharp and it works great. Hitting this roadblock is very frustrating.

Edit: When building the installer I found I have these error messages: WARNING: Unable to find dependency 'GLIB-SHARP' (Signature='35E10195DAB3C99F' Version='2.12.0.0') of assembly 'SkiaSharp.Views.Gtk.dll' WARNING: Unable to find dependency 'GTK-SHARP' (Signature='35E10195DAB3C99F' Version='2.12.0.0') of assembly 'SkiaSharp.Views.Gtk.dll' WARNING: Unable to find dependency 'GDK-SHARP' (Signature='35E10195DAB3C99F' Version='2.12.0.0') of assembly 'SkiaSharp.Views.Gtk.dll'

Looking into them further.

After a good deal of trial and error I copied libSkiaSharp.dll and libSkiaSharp.dylib from my build output directory to my installed application folder and it was able to load the DLL for SkiaSharp. I am trying to figure out how to include those files implicitly through assembly dependencies, but I can't figure it out currently.

erebuswolf commented 1 year ago

Right now I just explicitly add the files to the installer "application folder" from the release bin directory. This feels like a really bad solution as it will be pulling from release even if I want to make a debug build. If there is a better cleaner way to do this please let me know.

I would guess your installer is missing the contents of the runtimes directory which is where the platform-specific libSkiaSharp.dll can be found?

Thank you for the reply. After adding the runtime libs, I now am getting this from my installer log

DEBUG: Error 2727: The directory entry '_412412F434E7471BB49E4F29D2448DDD' does not exist in the Directory table

I'm not sure if this director is needed by skia or something else but it is a weird directory to require for my application. Do you have any clue why it would need this to exist?

Edit: The directory changes names every build, so it must be some auto-generated parth. I'm stumped again.

In our old project, has same error. copy nuget packages file "libSkiaSharp.dll" to bin path fixed this problem. It looks sime strange, why not auto copy libSkiaSharp.dll to bin path. .net framework is 4.6.2, platform is anycpu.
