Hi,

Solution (WorkAround) doesn't Work for me unfortunately.....

Still get

I posted this and Miguel answered previously with a workaround (I don't know about a fix). I put Miguel's answer below.

I had the exact same issue, I had to edit my LD_LIBRARY_PATH to point to /usr/X11R6/lib to make it work.

Am not sure why this is happening, I think the intention was to not depend on the "-devel" packages which are the ones that ship the version-less .so

In this process, someone forgot to test the code.

Subject: [Mono-winforms-list] An annoying problem

Hi,

Whenever I try to run a program compiled against MWF, I keep getting the same error

Unhandled Exception: System.TypeInitializationException: An exception was thrown by the initializer for System.Windows.Forms.XplatUI --->
System.DllNotFoundException: libX11.so.6.2

I know this has come up before and from what I remember when Miguel flagged it up was that there was a problem within XplatUI.

Is there a work around or will XplatUI be getting fixed sometime in the not too distant future?

TTFN

Hi,

I managed to reproduce the Problem on another machine...I had Mono 1.1.7 running on Suse 9.2, upgraded to SVN almost the same error occurred...except that the System.DllNotFoundException was stating libX11.so.6.2 was missing, which it is definitely not, and also the proper symlinks are there. Downgradeed to 1.1.7 Release...Everything is working again...

If I only substitute the System.Windows.Forms.dll in 1.1.7 with SVN Version, System.Windows.Forms Applications still run....Problem appears to be deeper...

Code, that causes the Problem (any SWF App, but also as simple code as following):

using System;
using System.Windows.Forms;

namespace WelcomeGUI
{
   class Welcome
   {
      public static void Main( string[] args )
      {
         MessageBox.Show( "Welcome\nto\nC#\nprogramming!" );
      }
   }
}


Thanks

What code caused the error to be generated?

That's quite old. Have you done a fresh checkout and build and seen if the problem still exists?
