Python 3.5 compatibility of cx_freeze

[Steltek]

Any way you could include this patch in the building to make cx_freeze compatible with Python 3,5?

https://bitbucket.org/anthony_tuininga/cx_freeze/pull-requests/83/python-35-compatibility-for-cx_freeze-4x/diff

Without this, you get this error: ImportError: No module named '_frozen_importlib_external'

What is your target build environment?

I got the error on a Debian testing (stretch) box. (Python 3.5.1+ (default, Jan 13 2016, 15:09:18))

Applying the diff to piaware_builder/package/cx_Freeze-4.3.4/cx_Freeze/finder.py fixed it.

It might make sense to do this as another distribution suite that sensible-build.sh knows about, as I wouldn't be surprised if there are other things that are specifc to stretch. If you want to send a pull request along those lines I can merge it (I don't have an environment to test stretch myself)

I updated sensible-build to use a more recent snapshot of cxfreeze (there is no new release yet), can you check if that fixes it? It fixes it for me on ubuntu xenial, at least, which has 3.5.2

Still getting this:

ah, sorry, did you build from the dev branch? Forgot to mention that

[mutability]

I had to revert this as it broke the Raspbian build; the development version is still not ready for real use by the looks of it.

I guess we are stuck with 4.3.4 for now, so I'll apply the patch you originally suggested
