[Mono-winforms-list] libgdiplus.dylib throws TypeInitializationException on Mac OS X (even with macpack)

[Chris Peterson]

I am trying to run a simple "Hello World" WinForms app on Mac OS X using mono 1.2.6, but I get a TypeInitializationException from (or regarding?) libgdiplus.dylib. I suspect libgdiplus.dylib might be trying to using X11 (which I do not have installed), even though I thought mono 1.2.6's WinForms no longer required X11 on Mac OS X.

I tried using macpack ("macpack -m:1 -n:helloworld -o:. -a:helloworld.exe"), but I still get the same TypeInitializationException when running macpack's helloworld.app (according to Mac OS X's Console utility).

If I run "MONO_LOG_LEVEL=info MONO_LOG_MASK=dll mono helloworld.exe", I get tons of DllImport errors/warnings about mono searching for libgdiplus.dylib . When mono finds libgdiplus.dylib, it then reports suspicious errors about X11:

Mono-INFO: DllImport loading: '/Library/Frameworks/Mono.framework/Versions/1.2.6/lib
/libgdiplus.dylib'.
Mono-INFO: DllImport error loading library 'dlopen(/Library/Frameworks/Mono.framework/Versions/1.2.6/lib/libgdiplus.dylib, 9): Library not loaded: /usr/X11R6/lib/libXrender.1.dylib 
  Referenced from: /Library/Frameworks/Mono.framework/Versions/1.2.6/lib/libgdiplus.dylib
  Reason: image not found'.

Any idea what I am doing wrong? Do I need still X11 to run WinForm apps on Mac OS X? Or do I have a lib path problem with mono or macpack? I've seen similar libgdiplus problems by Linux users on this mailing list, but I don't know if they are related to my Mac OS X woes. 


thanks!
