dh_auto_clean tries to use python instead of python3 when --with python3 specified

[Umang Varma]

I'm running debhelper 9.20120115ubuntu3

Here's an snippet from debuild output:

 fakeroot debian/rules clean
dh clean --with python3
   dh_testdir
   dh_auto_clean
  File "setup.py", line 3
SyntaxError: Non-ASCII character '\xc2' in file setup.py on line 3, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

Now, in Python3, UTF-8 is the default encoding. So it looks to me that it uses python2 instead of python3.

Status changed to 'Confirmed' because the bug affects multiple users.

I managed to get my package built from reading http://www.wefearchange.org/2012/01/debian-package-for-python-2-and-3.html. Specifically , I had to add a section to the debian/rules file:

#!/usr/bin/make -f

%:
 dh $@ --with python3

override_dh_auto_clean:
 set -ex; for python in $(shell py3versions -r); do \
  $$python setup.py clean -a; \
 done;

I'm attempting a PPA upload now of this package, so whilst the package built locally, I don't know if it actually works...but at least I don't get the error any more!

There is currently no python3 support in dh_auto_* build machinery. You need to do everything manually with python3. It is a known feature request.
