Webbrowser and Ubuntu

[chrisjob012]

Hi All,

I am trying to create a desktop application with webbrowser control in it.  I need this application run in ubuntu using mono. When i tried to run the application, an error comes up saying

Thread (nil) may have been prematurely finalized

but the application builds successfully.

I googled around and i came to know about libgluezilla.

I installed libgluzilla by using the command apt-get install libgluezilla.

But still the webbrowser control is not working.

Am I missing something?

Please help.

Regards,
Chris

Obviously, you also need xulrunner package installed -- check this.

It's not working how?  Do you get any error message on the terminal?

I'd go the most straightforward way:

apt-get install xulrunner

Probably.  Don't you think it's time to enlighten us on the subject of
what exactly is the error you get? :)

Hi Alex,

This is my scenario.

I have a C#.Net application that i have developed in Visual studio. This program is intented to run on Ubuntu. This application has a form with a webbrowser control in it. I basically need to display a flash file in the webbrowser control.

I have two Ubuntu machines, 1 is running on Ubuntu 8.10 and the second one is running on 8.04. When I open and run my application in MonoDevelop, I get two different errors.

in the first machine, i get an error -  Thread (nil) may have been prematurely finalized and in the second machine, I get an error - libgluezilla not found. To have webbrowser support, you need libgluezilla installed

I have installed libgluezilla and xulrunner in both machines using the apt command.

Hope you are clear with this.

Thanks
Chris

Hm, I remember a similar problem with gluezilla on my Ubuntu-9.4.  I
don't recall how exactly I solved it but suppose I've compiled mono and
gluezilla myself.

You can try running

MONO_LOG_LEVEL=debug mono myapp.exe | grep gluezilla

on the second machine.  In theory this should reveal which locations did
mono try to find the lib and why it doesn't find one.

About the problem on your first machine I have no idea.  Maybe others
have to say something about it.

What shoul I be doing?

Hi,

> What shoul I be doing?

Okay, this throwback is interesting.

For a start, why are you trying to load Mono 1.0 assemblies - have you
checked what you're referencing in the build file (or if you're using MD
what that shows)?

It looks like you need libgluezilla-devel (this is how it would be
called if it was on a Fedora box) - the .so files live in there.

libgdi32 comes from libgdiplus, again, have you got that installed on
your box (both the main package and the -devel package)?

Carbon is MacOSX - no idea why you're getting this on an Ubuntu box.
Again, check your makefile (or however you build the app)

libuxtheme - no idea what that is!

HTH

TTFN
