我无法部署单声道应用程序，因为o DllNotFoundException

Question

When I try to run my mono application using the following command:

mono SimpleBrowser.exe

I get the following error on my Mac:

Unhandled Exception: System.TypeInitializationException: An exception  was thrown by the type initializer for Gtk.Application ---> System.DllNotFoundException: glibsharpglue-2
  at (wrapper managed-to-native) GLib.Thread:glibsharp_g_thread_supported ()

I've tried searching for the missing glibsharpglue-2 library on my Mac but couldn't find it. I'm not sure what the problem is because the application runs when I launch it from Monodevelop.

You need to set this environment variable before executing your app:

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

Since this is a pain to do every time you execute your app, you should create a wrapper script that does it for you:

#!/bin/bash 
export DYLD_FALLBACK_LIBRARY_PATH="/Library/Frameworks/Mono.framework/Versions/Current/lib:/usr/local/lib:/usr/lib"
mono SimpleBrowser.exe "$@"

This is just a minimal sample, here is a bit more advanced:

#!/bin/bash 
MONO_FRAMEWORK=/Library/Frameworks/Mono.framework/Versions/Current/
export DYLD_FALLBACK_LIBRARY_PATH="$MONO_FRAMEWORK/lib:/usr/local/lib:/usr/lib"
EXE_DIR=`dirname $0`
$MONO_FRAMEWORK/mono $MONO_OPTIONS $EXE_DIR/SimpleBrowser.exe "$@"

And all you have to do is make sure the script is in the same directory as the executable to execute it. It allows allows you to pass options to mono (such as --debug for instance). This is usually how mono does it ( cat /usr/bin/mkbundle for an example), and it's in the offical Application Deployment Guidelines .

From a blog entry with a similar problem: http://ngeor.net/blog/post/2012/08/25/Mac-and-Mono.aspx Edit: updated link: http://ngeor.net/2012/08/mac-and-mono/

The problem here was with missing environment variables. I modified /etc/profile like this (the second and third line are supposed to be on the same line without the dots, I only broke it down to fit the page):

export MONO_FRAMEWORK_PATH=/Library/Frameworks/Mono.framework/Versions/Current export DYLD_FALLBACK_LIBRARY_PATH="$MONO_FRAMEWORK_PATH/lib:... ...$DYLD_FALLBACK_LIBRARY_PATH:/usr/local/lib:/lib:/usr/lib"
