Hi everyone,

I'm trying to compile GPS and link it against GTK-OSX =
(http://live.gnome.org/GTK%2B/OSX/Building), which provides a more =
native interface on MacOSX. So far, I succeeded in compiling the binary, =
but when I try to start it, it always fails to initialize Python (I =
linked against the Python framework that comes with MacOSX Lion). My =
first attempt looked like this:

$ ~/gtk/inst/bin/gps

Gtk-WARNING **: Locale not supported by C library.
	Using the fallback 'C' locale.
ImportError: No module named site

I guess the Gtk-WARNING can be ignored for now. The problem here is that =
Python does not know the directory where its modules are located. So I =
did:

$ export =
PYTHONPATH=3D/System/Library/Frameworks/Python.framework/Versions/2.7/lib/=
python2.7 =20
$ ~/gtk/inst/bin/gps                                                     =
                =20

Gtk-WARNING **: Locale not supported by C library.
	Using the fallback 'C' locale.
Traceback (most recent call last):

  File =
"/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sy=
sconfig.py", line 287, in _init_posix
    raise IOError(msg)
IOError: invalid Python installation: unable to open =
/Users/Felix/gtk/inst/lib/python2.7/config/Makefile (No such file or =
directory)

While Python does find its modules now, it still fails to load its =
configuration files. I tried to set the other python environment =
variables (PYTHONHOME, PYTHONFRAMEWORK, PYTHONBASE) to the corresponding =
places in the framework, but nothing changed. Python looks for its =
configuration in the installation prefix of GTK-OSX, where the GPS =
binary lies, instead of using the system's Python installation. I cannot =
tell whether this problem originates on the Python side or on the GPS =
side. Does anyone have advice?

Btw, I currently use GPS revision 177042, as this is the first revision =
I found that I succeeded to compile (with some modifications to the =
build system). I didn't have luck with the release version 5.0.1, nor =
with newer svn revisions.

Cheers,
Felix=
