Re: [gtk-osx-users] PyGTK on Lion

[Shrihari Sankaran <gfxindia gmail com>]

I did that. I edited that file and removed the _gtk.*. Then I ran "make && make install" from pygtk-2.24.0. Now, when I run the application, I get this:

/Users/gtk-osx/gtk/inst/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: RuntimeWarning: tp_compare didn't return -1 or -2 for exception
  from gtk import _gtk
ImportError: could not import pango
ImportError: could not import pango
(process:20928): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.

_RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL.
ImportError: cannot import name MenuShell from gtk
Fatal Python error: can't initialize module gtk_osxapplication:

Did I miss anything here?

Thanks,
Shrihari

Yeah, it's a libtool weirdness in the pygtk tarball that interacts badly with something in the 10.7 linker. It got hashed through last week in the forum [1].

Try this:
Edit pygtk-2.24.0/gtk/Makefile to replace "-export-symbols-regex" with "-export_symbol", delete .../gtk/.libs/_gtk.*, and rerun build.
