Re: compiling pygtk against gtk+ frameworks on osx

Hi, 
thanks for the response.

> the said framework on the site: http://www.gtk-osx.org/

here's the info from the installer window:

---------------------------------------
GTK+ 2.14

This package contains three frameworks needed for developing GTK+ applications natively on Mac OS X: GLib, Cairo and GTK+.

The frameworks contain the following components:

GLib:

  glib 2.18.1
  gettext 0.16
  intltool 0.40.4

Cairo:

  cairo 1.7.6
  pixman 0.12
  libpng 1.2.29

GTK+:

  gtk+ 2.14.3
  pango 1.22.0
  atk 1.24.0
  ige-mac-integration 0.8.2
  gnome-icon-theme 2.24.0
  hicolor-icon-theme 0.10
  gtk-engines 2.16.0 (only Clearlooks)
  libpng 1.2.29
  tiff 3.8.2
  jpeg 6b


The frameworks are developer versions with debugging symbols and the necessary setup for building both Xcode projects and "autotools" projects against them. Note that Xcode 2.5 or later is needed. See:

  http://developer.imendio.com/projects/gtk-osx for more information.

Note that this package is still in a beta phase, in particular, the exact selection of libraries and tools included in the frameworks might change in the next version. Therefore it is best not to distribute the frameworks as standalone frameworks, but only included inside application bundles for now. Tools to produce standalone app bundles using those frameworks will be provided later.

---------------------------------------

the provided link is dead.  the frameworks install dirs are:

/Library/Frameworks/Cairo.framework
/Library/Frameworks/GLib.framework
/Library/Frameworks/Gtk.framework

you're referring to the --prefix=/System/Library/Frameworks/Python.framework/Versions/2.6/ that i have set, i imagine.   you're right, that's probably not a fantastic idea.  i know that the installer looks for site-packages in ${prefix}/lib/python2.6/site-packages.  this exists for the system path, but not for the proper local path, which is /Library/Python/2.6/site-packages. i should probably just compile to a separate location.

this is the kind of info i was hoping for.  now that i know to look, i see that the frameworks do in fact come with .pc files:

gio-2.0.pc
gio-unix-2.0.pc
glib-2.0.pc
gmodule-2.0.pc
gmodule-export-2.0.pc
gmodule-no-export-2.0.pc
gobject-2.0.pc
gthread-2.0.pc

i know that the versions say 2.0, but i think this is a common framework practice to truncate all but the primary version.  the installer says the version is of glib is 2.18.1

so, after exporting the PKG_CONFIG_PATH env var to the appropriate dir, configure still cannot find glib.

$chad> export PKG_CONFIG_PATH=/Library/Frameworks/GLib.framework/Resources/dev/lib/pkgconfig
$chad> ./configure --prefix=/usr/local/pygtk
[...]
checking whether to enable threading in pygtk... yes
./configure: line 11833: ./libtool: No such file or directory

checking for GLIB - version >= 2.8.0... no

*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GLIB is incorrectly installed.
configure: error: gobject is required to build pygtk?

also, i'm not sure if i should be concerned about the ./libtool error....

yeah, i've used darwinports and compiled from scratch, but there's always a hiccup along the way that leaves me stumped. these frameworks are perfect, i'm ready to compile apps in xcode after a 30 second install.... pygtk is the only hiccup now.

thanks for the help. it is greatly appreciated.
