Re: Catching Glib::FileError when its thrown in a DLL

[Adam Chyła <adam chyla tk>]

Hi,
If you are using gtkmm from this site 
http://ftp.gnome.org/pub/GNOME/binaries/win32/gtkmm/
you have to use MinGW64 compiler
http://mingw-w64.sourceforge.net/

You can also compile Gtkmm by oneself.

Best regards,
Adam
