[Mono-osx] My Project Files Moved & Susan's Xcode Plug-in

Hi Folks,

First off, I've had to move MonoTool & CocoaSharpApplication projects  
from their previous location - Joomla started giving me lot's of  
funny errors. They can now be found by following the links below:
http://people.bath.ac.uk/cs3ms/MonoTool.tgz
http://people.bath.ac.uk/cs3ms/CocoaSharpApplication.tgz

I've also added them to one of my journal entries on .Mac so that  
they don't disappear when I graduate.

I've also been playing with Susan's wonderful Xcode plug-in. Ken  
didn't seem to have much luck with it on his G4 iMac, but I've only  
run in to a few problems on my 12" PB (1GHz G4, 10.4.8, Mono 1.1.18,  
Xcode 2.4).

1. Compiling the default Hello-World! app results in the following  
error:
"[Session started at 2006-10-15 16:51:51 +0100.]

Unhandled Exception: System.TypeInitializationException: An exception  
was thrown by the type initializer for System.Console --->  
System.NullReferenceException: Object reference not set to an  
instance of an object
   at System.TermInfoDriver.Init () [0x00000]
   at System.ConsoleDriver.Init () [0x00000]
   at System.Console..cctor () [0x00000] --- End of inner exception  
stack trace ---

   at <0x00000> <unknown method>
   at InstallTest.InstallTest.Main () [0x00000]
   at InstallTest.InstallTest.Main () [0x00000]

InstallTest has exited with status 1."

By setting the .NET version flag to V1 in the Build tab of the Target  
Info inspector window I got the expected output:
"[Session started at 2006-10-15 16:54:05 +0100.]
Goodbye, Forever!

InstallTest has exited with status 0."

What is interesting though is that if you run the V2 compiled program  
from Terminal (or WidgetTerm) it works perfectly. After some poking  
around in the project file, plug-in code and various templates I  
can't see what's going wrong. Could it be a bug in GMCS/Mono on PPC  
or in Xcode on PPC with regards to Xcode's Pseudo Terminal?

2. Adding C Sharp/Executable targets doesn't really work. Adding an  
executable generates the target & it appears OK, but the associated  
Executable is not configured to run /usr/bin/Mono. Also, changing the  
build setting to Release and pressing Build does not actually build  
anything. Haven't checked into this to see what's really going on, so  
it could very well be something I'm doing wrong.

Finally, if you would like me too I'll make the time to make the  
CocoaSharpApplication a proper project template and then someone can  
add it to the files distributed with the plug-in.

Frankly I'm really impressed with the work Susan has put into this  
plug-in as it does seem to work reasonably well most of the time.  
When I get my new Macbook Pro (sometime in the next week) I'll try  
comparing Intel/PPC in the (probably vain) hope that it might  
illuminate some of the odd behaviour on PPC. I spent most of the  
summer working in Objective-C and Cocoa, though I would not claim to  
be any kind of expert, so I should be able to track down at least  
some of the bugs. Of course my doing this shouldn't stop the more  
experienced programmers out there from having a go.

Thanks Susan!

Mark
