Description Michael Terry 2011-11-10 19:07:17 UTC

Description of problem:
When building on a 64-bit system against Python 3.x, hivex issues warnings like:
../../../python/hivex-py.c:810:3: warning: implicit declaration of
function 'Py_InitModule' [-Wimplicit-function-declaration]

This is almost certainly a bug.  The problem seems to be the use of PyString_* instead of PyBytes_*.  PyString_* is no longer available on Python 3.x.

How reproducible:
Always

Steps to Reproduce:
1. Build on amd64 with Python 3.x

Additional info:
See Debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=646383

Comment 1 Richard W.M. Jones 2011-11-10 19:50:54 UTC

We don't yet support python 3 in hivex, but ought to.

Comment 3 Richard W.M. Jones 2011-11-19 17:03:01 UTC

In case it's not clear, you can select which Python to use
by exporting the PYTHON environment variable before ./configure,
eg:

  PYTHON=python3 ./configure
