[Gtk-sharp-list] Error running test app on Windows (was: Gtk# 2.99.3 released)

Sun Jun 15 18:29:26 UTC 2014

Hello Betrand,

thanks for looking ;). On Point 4 you mentioned, that running the FileChooserDialog failed, that's what I also got (I also tried with commenting out gstreamer stuff). So is this a bug of Gtk# 2.99.3 for Windows?

As you guessed, gstreamer for windows ships along with libpixman-1.0.dll, so what can I do now? I'm a bit confused :(.

Thanks for helping me :).

Greetings
Sven

Hi,

Thanks for the code.
I've played around with it, and here's what I saw:

1/ On Windows with Xamarin Studio 5.0 I had to add a reference to gio-sharp.dll to build successfully. That's because Gtk.Application derives from GLib.Application, which is in gio-sharp.
This is probably Xamarin Studio/MonoDevelop being more strict in version 5.0, so unrelated with your error.

2/ You should not have to install GTK+ itself, all the necessary native binaries should be in the Gtk# installer.

3/ I commented out the GStreamer stuff, because I don't have it on my Windows machine.

4/ After that, I was able to run the app, but opening the FileChooserDialog failed with an error about missing GSettings schema.
The GSettings schemas are installed by the MSI, so I'll have to look into what's wrong here.

Now I've just got an idea:
Your app uses GStreamer 1.0 through GStreamer#. Where did you get the Windows binaries for GStreamer 1.0 ?
I'm thinking maybe they have their own copy of libpixman-1-0.dll, which clashes with the one provided by Gtk# and causes the error you have ?

I hope this helps.
