[PATCH 1/1] glib-2.0-native: do_compile failed on opensuse 12.2 64bit

[Robert Yang]

The error message:
  File "/path/to/glib-2.34.3/gio/gdbus-2.0/codegen/parser.py", line 25, in <module>
    import xml.parsers.expat

ImportError: No module named xml.parsers.expat
make[2]: *** [gdbus-daemon-generated.h] Error 1

This is because opensuse 12.2 doesn't install the expat.py (one of
python's lib) by default, but our native python provides it, use the
native python would fix the problem.

I don't like this.

xml.parsers.expat is a standard Python library that's been integrated since 2.0:

http://docs.python.org/2/library/pyexpat.html#module-xml.parsers.expat

If we can't assume that a distribution has shipped a working Python
we've got bigger problems.

We could sanity check this in some way, maybe in the recipe's
configure step so we can give a nicer message, but I don't think we
should depend on pythonnative when we're talking about a standard
feature of Python.

Hi Ross,

Thanks for the review, please see more comments:
The glib-2.0-native had already depend on python-native before this patch,
the depends chain is:

glib-2.0-native -> python-argparse-native -> python-native

I inherit the glib-2.0-native is for using the ${PYTHON} variable, it doesn't
change its depends, since we had built python-native already, and it works,
it seems more reasonable to use it rather than show error message and let the
user install other pkgs on the host, I think that this is what our native
recipe for.

That argparse usage was dropped from upstream in 2.30, so we can drop
the dependency.

I still think that we shouldn't have to build a whole python because a
distribution decided to not install fundamental parts of Python out of
the box (python-xml).

We may need to have a mechanism to specific build dependencies for
native depending on host version/distribution.

The situation is that Suse splits the expat parser into a separate
package for some reason, so the "fix" is to actually install the whole
Python core library by installing python-xml if it isn't already
pulled in.  We could add a sanity test that the python available is a
full python and not missing the expat parser (suse without python-xml)
or isn't python-minimal (ubuntu).

Yes; this might be a solution.

OK, got it, I will file a new patch sooner.
