OSx mono gtk hello world. An exception was made for Gtk.Container

Question

An attempt to use hello world examples in Mono after a new installation. Tried an example of GTK, as stated in [ http://www.mono-project.com/docs/getting-started/mono-basics/†[1] :

mcs hello.cs -pkg:gtk-sharp-2.0
mono hello.exe

and I get the following:

Any idea what causes it?

Answer 1

Jonathan Prior answered very well on the Xamarin forum . These bits from his answer helped me:

You are not exporting $ DYLD_LIBRARY_PATH or $ DYLD_FALLBACK_LIBRARY_PATH so that it can be found.

...

, libgtk-quartz-2.0.0.dylib , /Library/Frameworks/Mono.framework/Libraries, /usr/lib ( - ).

, mono hello.exe :

export DYLD_FALLBACK_LIBRARY_PATH=/Library/Frameworks/Mono.framework/Versions/Current/lib:/lib:/usr/lib

Answer 2

,

"userSpaceScaleFactor NSView 10.7

GTK. GTK , Apple .

Apple Dev re userSpaceScaleFactor

A script, . chmod + x.

#!/bin/zsh
export DYLD_FALLBACK_LIBRARY_PATH=/Library/Frameworks/Mono.framework/Versions/Current/lib:/lib:/usr/lib

mono $1.exe
