GIO# FileFactory.NewForCommandlineArgs System.EntryPointNotFoundException

[Dan Saul]

Hi,

I have compiled Mono# from SVN to get access to GIO#. For the most part it works, I have no problem with the code:

base_dir = FileFactory.NewForPath(v);

However if I change it to

base_dir = FileFactory.NewForCommandlineArgs(v);

I would like to change this so that one can enter a URI or a Path on the command line.

I recieve the following exception:

Unhandled Exception: System.EntryPointNotFoundException: g_file_new_for_commandline_args
  at (wrapper managed-to-native) GLib.FileFactory:g_file_new_for_commandline_args (string)

Looking at the source svn://mono/gtk-sharp/gio/FileFactory.cs the two methods are the following:

        [DllImport ("libgio-2.0-0.dll")]
        private static extern IntPtr g_file_new_for_path (string path);
       
        public static File NewForPath (string path)
        {
            return GLib.FileAdapter.GetObject (g_file_new_for_path (path), false) as File;   
        }

        [DllImport ("libgio-2.0-0.dll")]
        private static extern IntPtr g_file_new_for_commandline_args (string args);

        public static File NewForCommandlineArgs (string args)
        {
            return GLib.FileAdapter.GetObject (g_file_new_for_commandline_args (args), false) as File;       
        }

I do not see a difference between them.

I am relatively new to C# so I do not know how to troubleshoot this. Would anyone be able to point me in the right direction?

Dan

Yes, the GIO function is actually called g_file_new_for_commandline_arg
  ;-) . Attached is a simple patch to fix the issue(I think we can break
compatibility here since the old implementation was non-working).
Stephane, could you review? I assume the patch has to go into the
gio-sharp module as well?
