[SciPy-Dev] Compiling scipy 0.13.2 with Python 3.4 rc 1

[Stephen Simmons]

Hi all,

In case anyone wants to try scipy with the new Python 3.4, there is a 
problem with importlib in rc1 that results in import errors while 
building scipy. Basically f2py can't do its imports properly and some 
autogenerated code comes out with missing symbols. It can be hard to see 
this amidst the stream of build messages and warnings. They show up 
clearly though when starting python3.4 and running scipy.test(). First 
time through I got 174 failing tests.

If you don't want to wait for Python 3.4 rc2, you can download the fixed 
version of importlib.__init__.py from here (updated on 12 Dec):
http://hg.python.org/cpython/file/c1a7ba57b4ff/Lib/importlib/__init__.py

After doing this, I removed numpy and scipy (sudo pip3.4 uninstall numpy 
etc), recompiled numpy and scipy, and got no test failures (using Linux 
Mint 14).

Stephen
