[Mono-winforms-list] running winforms application on OS X

[Paul Berry]

HI all, hopefully someone can help with this, I've been googling for
answers to this problem for 2 days now without any luck.

 

Basically, I'm at the stage where my application (originally written in
.Net, ported to mono on linux, now trying to port to OS X) compiles
fine, but running it provokes the error at the bottom of this message.

 

Further testing has revealed that this error occurs for *any* mono
application.  Googling has revealed several cases of this error with
winforms on OS X but no useful solution.  I've tried copying fonts from
my windows machine to ~/fonts and running mkfontdir on that directory
but this results in 'Bus error'.  

 

Please help!

 

Here's the error:
