Description Narcís Calvet 2013-03-07 03:23:49 UTC
Creating a new empty Gtk# 2.0 application either in latest MonoDevelop or Xamarin.Studio fails to run with MacOSX 10.8.2. It runs fine with 10.7.5. System.Windows.Forms & Microsoft.VisualBasic usage also fails, for more detailed info please read this thread: http://forums.xamarin.com/discussion/1888/interaction-inputbox-crashes-in-mac-osx

Running the generated .exe via command line through mono also fails. As Jonathan Pryor suggests in the thread aobve, this might be another bug so I'll file it in separately.

Comment 2 Mikayla Hutchinson [MSFT] 2013-03-07 20:56:11 UTC
I think the dllmaps should have absolute paths to the libraries so DYLD_FALLBACK_LIBRARY_PATH is not needed?
Comment 3 Narcís Calvet 2013-03-08 03:02:02 UTC
Sorry if I didn't explain the issues correctly. I submitted two of them upon Jonathan Pryor's request at http://forums.xamarin.com/discussion/comment/6749#Comment_6749. IMO one issue is about System.Windows.Forms & Microsoft.VisualBasic and the other one is about Gtk#. Both of them are about not working properly on Mac OSX 10.8.2 though.
Comment 4 Narcís Calvet 2013-03-08 03:03:03 UTC
About comment #2, would you like me to test something at my end? Thanks.
Comment 5 Mikayla Hutchinson [MSFT] 2013-03-08 16:21:33 UTC
I marked it duplicated because both bugs appeared to me to be about the same GTK# issue. If you'd like to open a bug specifically for Windows Forms, please go ahead.

@Duncan: did we lose the code for making dllmaps absolute in the bockbuild migrations?

@Narcís: it's easy to work around this, just 
export DYLD_FALLBACK_LIBRARY_PATH=/Library/Frameworks/Mono.framework/Versions/Current/lib:/lib:/usr/lib:$DYLD_FALLBACK_LIBRARY_PATH
You can do this in you terminal, and also in you app's launch script.
Comment 6 Alexis Christoforides 2015-09-29 11:16:53 UTC
Mono now searches the Mono installation's library path for DllImport/dllmap entries without absolute paths.

https://github.com/mono/mono/commit/a29f5292e61a1f45c0bc6d15ef112fde4cf846b4

GTK# applications should now work without DYLD_FALLBACK_LIBRARY_PATH overrides in the latest packages.
