RE: Getting Gtk3 to work with PAR

Hi there, 

To pack my Gtk2 applications, I set up the following on my Windows box:

- pp -B --lib c:\strawberry\perl\vendor\lib 
-l "C:\strawberry\perl\site\lib\auto\Cairo\Cairo.dll" 
-l "C:\strawberry\perl\site\lib\auto\Pango\Pango.dll" 
-l "C:\strawberry\perl\site\lib\auto\Glib\Glib.dll" 
-l "C:\strawberry\perl\site\lib\auto\Gtk2\Gtk2.dll" 
-o foo.par foo.pl

- unzip the par files

- removed the lib/auto/Gtk2, lib/auto/Cairo lib/auto/Pango from the par unzipped directory

- zipped all the directory tree back into foo.par

- pp -o foo.exe foo.par

I usually run this using a batch file and it works at the end.
