Re: can't run 0compile on windows .

Hi guys,

the C# solver always tries to find a 64-bit solution first when running on a
64-bit system and only considers 32-bit solutions if that fails.
http://repo.roscidus.com/python/python-gobject only has an i486 build for
Windows. Therefore it cannot be part of a valid 64-bit selection.
http://0install.net/2007/interfaces/ZeroInstall.xml still lists some
versions without a dependency on python-gobject, e.g. 1.14.
Therefore the solver will prefer to use this old version of Zero Install
rather than falling back to i486 for the entire selection and thus end up
still providing a solution leading to "No module named gobject".
Since the C# solver uses simple backtracking rather than a SAT solver, it
takes quite some time to find this solution.

The following works on Windows and only takes a few moments:
> 0install run --cpu=i486 http://0install.net/2006/interfaces/0compile.xml

@Thomas: If you could add the python-gobject dependency to the remaining
implementations in the ZeroInstall feed I believe it would prevent this
issue.
However, the solver would probably still take a long time until it realizes
it has to down 32-bit lane.
In order to speed up the process I suppose we should also add the
python-gobject dependency directly to the 0compile feed.

Further down the road, I have some optimizations for the C# solver planned,
as time permits.

Regards
Bastian

	It is falling back to the ocaml solver according the the -vv logging
Specifying the version selects quite a bit faster

It takes 137 seconds without the version

Even with the version though it still fails the same way
