System.DllNotFoundException: libgdk-win32-2.0-0.dll on macOS (El Captain - 10.11.6)

[behrooz shabani]

Hi all,

I am trying to build the HelloWorld based on the instructions that is available in README so far, I have built Xwt:

⋊> ~/w/d/client on master ⨯ gfind -name 'Xwt.dll' | grep Release

./xwt/Xwt/bin/Release/Xwt.dll

./xwt/Xwt/obj/Release/Xwt.dll

./xwt/Xwt.Gtk/bin/Release/Xwt.dll

and I I have added a reference to the first file in that list (README reads "This is the only library that you need to reference at compile time"). However, I get the following exception:

System.TypeInitializationException: The type initializer for 'Xwt.GtkBackend.GtkWorkarounds' threw an exception. ---> System.DllNotFoundException: libgdk-win32-2.0-0.dll

  at client.XwtDemo.Main () [0x0003a] in /Users/behrooz/work/deskbit/client/client/Main.cs:19

The source code:

using System;

using Xwt;

namespace client

{

class XwtDemo

{

[STAThread]

static void Main()

{

Application.Initialize(ToolkitType.Gtk);

var mainWindow = new Window()

{

Title = "Xwt Demo Application",

Width = 500,

Height = 400

};

mainWindow.Show(); // this is line 19

Application.Run();

mainWindow.Dispose();

}

}

}

Any idea what could be the problem and how I can fix it?

P.S. The application that I am trying to make is a webview (https://github.com/mono/xwt/blob/211d0e207fd974962bf69cb68b7214945bc1b4bb/TestApps/Samples/Samples/WebViewSample.cs) with a bunch of methods exposed via JS. So if you have pointers regarding that, I'd appreciate it because I can't find anything related to enabling JS for the webview here: https://github.com/mono/xwt/blob/44b564d92966fbfa789edb3e090609b218fc4529/Xwt/Xwt/WebView.cs.
